Definitions

  • the present invention relates to the field of valves, and more specifically, to valve for preventing backflow from an air bag having an actuating mechanism that includes a moveable plug and a valve body and a massaging system using the same.
  • a valve is a device that regulates the flow of fluids (gases, fluidized solids, slurries or liquids) through the opening, closing, or partially obstructing of various passageways.
  • Valves are made up of a valve body with two or more openings, which are often called the ports of a valve, and an actuation mechanism. Through the ports, fluid can enter or leave the valve as the actuation mechanism acts to open and/or close particular ports of the valve body.
  • valve ports are often connected to piping or tubing.
  • an actuation mechanism may be taken to a solenoid.
  • a “solenoid” generally refers to a device that converts electromagnetic energy into kinetic energy such as linear motion, for example.
  • the term “solenoid valve” therefore refers to an integrated device having an electromechanical solenoid and a valve body.
  • the solenoid consists of a balanced or easily moveable core (or plunger), which channels the fluid into or from the appropriate port by opening or closing channels and passageways in the valve body.
  • solenoid valve In the regulation of fluidic (pneumatic and hydraulic) systems, the use of such a solenoid valve typically allows a small electric current (continuous or pulse) to be applied to the solenoid to control fluids at pressures of about 12OkPa or 1.2bar, for example.
  • the assembly includes an inlet channel through which air is passed through and several sequential or consecutive openings in fluid connection with the inlet channel,
  • the air flow into the sequential or consecutive openings is governed by a solenoid at each of the openings wherein said solenoid has a further fluid connection to an air bag. Accordingly, if it is desired to inflate a particular air bag, the solenoid governing the opening associated with said air bag is actuated to allow air to flow into said opening and then on to the air bag.
  • a second air bag in sequential fluid connection with the first, i.e. the two air bags share a common fluid source
  • commence inflation concurrently after the first air bag is partially (or substantially) inflated
  • the air of the first air bag tends to rush from the first air bag into the second air bag thereby creating a sudden loss of pressure in the first air bag.
  • the flow of air against its intended path (or in this case out from the first air bag and into the second air bag) is known as "backflow".
  • Backflow results in a loss of pressure, which may be substantial and typically lasts in the first air bag until the pressure In the first air bag and the second air bag equalizes. Only after the pressure equalizes can the first air bag resume inflation.
  • the valve body includes an inlet channel and an outlet channel in fluid communication with each other via at least one feed channel.
  • the fluid feed channel extends from an inlet channel - feed channel junction to a feed channel - outlet channel junction.
  • the feed channel comprises at least one feed port adapted to be connected to an air bag and at least two valve seats.
  • One valve seat is located proximate to the inlet channel - feed channel junction and the other valve seat is located proximate to the feed channel - outlet channel junction.
  • Each valve seat is adapted to accommodate the moveable plug such that the fluid flow from the inlet channel into the feed channel, and from the feed channel into the outlet channel, is regulated by the respective plugs.
  • the valve seats in combination with the respective plugs, operate as valves.
  • the feed channel also includes a check valve located between the feed port and the inlet channel - feed channel junction such that fluid flow from the feed port into the inlet channel is prevented.
  • the valve body may include a plurality of feed channels wherein the fluid flow across each of the plurality of feed channels originates from the inlet channel and terminates in the outlet channel.
  • such an arrangement of the feed channels results in the fluid flow across one feed channel being parallel with respect to the fluid flow across another feed channel.
  • the check valve may be located between the feed port and the valve seat, proximate to the feed port.
  • the check valve is physically located nearer to the feed port.
  • the feed channel may include a second check valve located between the feed port and the feed channel - outlet channel junction such that fluid flow from the outlet to the feed port is prevented. More specifically, the second check valve may be located between the feed port and the other valve seat, but proximate to the feed port.
  • the check valve may be any suitable valve that allows a uni-directional flow.
  • valves include, but are not limited to, a ball check valve, a single disc swing check valve or a double swing disc check valve.
  • the ball check valve may be complemented with at least one return spring.
  • the return spring is located within the feed channel and is arranged such that it is biased to return a ball of the ball check valve to its initial position between the feed port and the inlet channel - feed channel junction or feed channel - outlet junction, respectively. Furthermore, the return spring also prevents the ball from blocking the feed port entrance (during inflow) and also the feed channel (during and after any back flow).
  • each valve seat may be adapted to accommodate a plunger of a solenoid, where said plunger essentially functions as the plug.
  • the valve seats in combination with the respective plungers, operate as valves.
  • the adaptation of the valve seat to accommodate a plunger of a solenoid may be in the form of a mechanical coupling (e.g. screws) between the valve seat and the plunger of the solenoid. As such, the valve seat is opened and closed by the movement of the plunger of the solenoid.
  • valve seat is typically adapted to form an air-tight seal with the plunger of the solenoid when the plunger closes the valve seat. This is necessary in order to prevent a loss of fluid via leaks, for example.
  • An example of a typical air-tight seal is a rubber oil ring to seal up two opposing surfaces between the valve seat and valve body.
  • the spatial arrangement of the inlet channel and outlet channel may be such that the two channels run at least substantially parallel to each other.
  • the feed channel extends from the inlet channel to the outlet channel in an at least substantially perpendicular manner.

  • the three parts are subsequently joined together by ultra sonic welding.
  • the fabrication of the valve body is further described in Figures 6 and 7 later on.

  • a ball check valve typically includes a restriction in the cross-sectional area of a tube and a ball of diameter greater than that of the restriction situated on one side of that restriction.
  • the ball valve 204A is situated between the valve seat 224 and the feed port 106 with proximity towards the feed port 106.
  • ball valve 204A is provided to prevent fluid from flowing from the feed port 106 into the inlet channel 102 when the valve seat 224 (inlet valve seat) is open.
  • ball valve 204B is situated between the valve seat 228 (outlet valve seat) and the feed port 106 with proximity towards the feed port 106.
  • Ball valve 204B is provided to prevent fluid from flowing from the outlet channel 104 into the feed port 106. The detailed functioning of the ball valves 204A and 204B will be further explained below.
  • the feed channel 202 also includes valve seats 228 and 224.
  • Valve seat 224 is located proximate to the inlet channel - feed channel junction 226 while the valve seat 228 is located proximate to the feed channel - outlet channel junction 222.
  • the valve seats 224 and 228 accommodate the moveable plungers 210 therein.
  • the moveable plungers 210 rest on springs 214, which are in turn supported by plunger bases 216. Surrounding each plunger 210, spring 214 and plunger base 216 is a wire coil 212. Also surrounding each plunger 210 is a magnet 208. In a default state, the magnet 208 holds the plunger 210 in a position such that the spring 214 is compressed and the valve seat 224, 228 is open, i.e. for example, fluid from the inlet channel 102 may flow into the feed channel 202 and to the feed port via the valve seat 224. In order to actuate the plunger to close the valve seat 224, an electric current may be passed through the wire coil 212 thereby causing the wire coil 212 to generate a magnetic field.
  • the plunger 210 On generating the magnetic field, the plunger 210 is pushed forward by said magnetic field and coupled with the spring force from the now released spring 214, the magnetic force holding the plunger 210 in its default state from the magnet 208 is overcome and the plunger moves vertically upwards thereby closing the valve seat 224. Electric current may be cut off at this time and the plunger 210, which sealed the valve seat 224, is maintained at the position by the spring 214.
  • the plunger includes a rubber seal 206 that forms an air tight seal on contact with the valve seat 224 thereby preventing any fluid from flowing from in the inlet channel 102 into the feed port 106.
  • this arrangement of the solenoid and plunger 210 having a magnet 208 is known as a "KEEP solenoid". Accordingly, when the electric current is passed through the coil 212 a mere pulse is sufficient to cause the positioning of the plunger 210 to change.
  • the use of this type of solenoid permits the amount of current supplied, and therefore the amount of heat generated by the solenoid, to be kept to a minimum. This is especially important in the case where the valve mechanism is employed in direct contact or in close proximity to a user. It should also be noted that although the workings of the keep solenoid have only been described with respect to the valve seat 224, the same working principle applies to the other valve seat 228 and its corresponding solenoid and plunger 210 as well.
  • Figure 3 shows a cross sectional view of the valve mechanism about the line A-A of Figure 1 during an inflation sequence.
  • the plunger 210 associated with the inlet channel 102 moves vertically downwards thereby opening its corresponding valve seat 224. Fluid from the inlet channel 102 flows into the feed channel 220 and displaces the ball valve 204A from the restriction. Said fluids continue to flow into the feed port 106 as indicated by the arrow.
  • the valve seat 228 may be either open or close, though it is preferable that it be closed since any leak from the feed channel 202 into the outlet channel 206 should be avoided.
  • FIG 4 shows a cross sectional view of the valve mechanism about the line A-A of Figure 1 during a holding sequence.
  • the fluid is to be held within the feed channel 202.
  • the fluid is to be contained within the boundaries of the ball valve 204A, feed port 106 and valve seat 220.
  • both valve seats 224 and 220 are closed by their respective plungers 210.
  • the fluid may attempt to flow out from the feed port 106 and thus pushes the ball valve 204A close and is maintained in the feed channel 202 by the closed valve seat 220 as well.
  • the valve seat 224 may be open, as the ball valve 204A already prevents the flow of the fluid from the feed port 106 into the inlet channel 102, as a precaution, it is best to have said valve seat 224 closed as well.
  • Figure 5 shows a cross sectional view of the valve mechanism about the line A-A of Figure 1 during a deflation sequence. During this sequence, the valve seat 224 remains closed while the valve seat 220 is open. Due to the open valve seat 220, the fluid flows from feed port 106 into the outlet channel
