Definitions

  • the present invention relates generally to an improved fluid connection connecting a fluid inlet and a fluid outlet.
  • the invention has particular application in respect of an oxy-acetylene cutter and will be generally described in that context. However, it is to be understood that the invention can have a broader application and can be used in a variety of applications where it is desirable to move an inlet relative to an outlet while maintaining fluid communication between the inlet and outlet.
  • Oxy-acetylene cutters have been traditionally manufactured with a handpiece having a gas/flame outlet nozzle which directs a flame a fixed 90° relative to the long axis of the handpiece. While this particular fixed orientation of the flame to the handpiece is suitable for a variety of applications, it has been found that the existing configuration can be confining, uncomfortable and potentially unsafe when used in a limited space, overhead or when cutting material in certain orientations.
  • the orientation of the flame nozzle requires a user to hold the handpiece angled with the long axis at a generally parallel orientation to the roof. This results in the flame being directed in a substantially vertical position, close to the head of the user. Such an orientation is dangerous as it can result in a shower of sparks and metal showering down on the user. Furthermore, it is uncomfortable for a user to maintain the handpiece in this position for an extended length of time due to the angle the user must hold the handpiece to accurately aim the flame at the roof.
  • a pivotable fluid connector including;
  • a first section mounted about a pivot axis, the first section having a fluid inlet in fluid communication with a linking outlet;
  • a second section mounted in engagement with the first section about the pivot axis, the second section having a linking inlet in fluid communication with a fluid outlet, the first section and second section being movable relative to one another about the pivot axis from a first position in which the fluid inlet is orientated in a first orientation relative to the fluid outlet to a second position in which the fluid inlet is orientated in a second orientation relative to the fluid outlet; wherein the linking outlet and the linking inlet are in fluid communication in both the first position and second position thereby allowing fluid to flow through the connector between the fluid inlet and fluid outlet in each of the first position and second position.
  • the fluid connector of the present invention therefore allows the fluid inlet of the first section to move a selected angle away from the fluid outlet of the second section about the pivot axis while maintaining a fluid connection between the fluid inlet and fluid outlet. Accordingly, if the connector is used in a handpiece of an oxy-acetylene cutter, the fluid inlet of the connector can be connected in a section of the gas feeder pipes leading to the flame nozzle, so that a first portion of the gas pipes are fixed to the fluid inlet of the connector and the remaining portion including the flame nozzle is connected to the fluid outlet of the connector.
  • the connector will allow the flame nozzle to be rotated a selected angle relative to the rest of the handpiece while still allowing gas flow to be maintained to the flame nozzle in each of these positions.
  • the degree of freedom of the connector is dependent on the desired positions that the fluid inlet is to be located relative to the fluid outlet for a certain application.
  • the configuration of the each of the linking inlet and linking outlet is selected to provide a fluid connection between the fluid inlet and fluid outlet of the connector over this entire angular range.
  • the angular range can be any angle greater than 0°, though is typically between 45° to 360°.
  • the fluid link between the fluid inlet and fluid outlet of the connector is formed through the interaction of the linking inlet and linking outlet.
  • Each of the linking inlets and linking outlets is preferably located proximate to the intersection of the first and section sections of the connector. More preferably, each of the linking inlets and linking outlets is formed between a portion of the first section and portion of the second section which are in engagement. Typically, the portion of the first section is in engagement with a portion of the second section forms a fluid tight seal.
  • the linking inlets, linking outlets or combination comprises a recessed section formed in either the first or second section of the connector.
  • the recessed section can take the form of a cavity, trench, groove or the like.
  • the connector includes two or more fluid conduits, each fluid conduit having a fluid inlet, fluid outlet, linking
  • each conduit defines separate fluid connections between a fluid inlet, fluid outlet.
  • some or all of the individual fluid conduits are linked in some manner within the connector.
  • each linking inlet, linking outlet or combination have individual inlet(s) and/or fluid outlet(s).
  • each linking inlet, linking outlet or combination have shared fluid inlet(s) and/or fluid outlet(s).
  • the pivotable fluid connector of the present invention can also act as a mixer of different fluids being fed into the connector.
  • a linking outlet of the connector could be in fluid communication with more than one fluid inlet.
  • a linking inlet of the connector could be in fluid communication with more than one fluid outlet.
  • a pair of linking inlet and linking outlet about the pivot axis provides the flexibility in positioning of the fluid inlet relative to the fluid outlet while maintaining fluid flow.
  • at least one of the linking inlet or linking outlet has an annular configuration having a centre about the pivot axis.
  • the annular configuration is advantageous as each of the sets of linking inlets and linking outlets can be concentrically arranged about the pivot axis.
  • An annular configuration can comprise a full 360° circumference about the pivot axis or part thereof.
  • two or more individual sets of linking inlets and linking outlets could be spaced apart around a circumference about the pivot axis.
  • two or more circular trenches could be arrange concentrically within either the first section, second section or combination thereof of the connector to form the various sets of linking inlets and linking outlets of the connector.
  • the fluid inlet and fluid outlet of the connector can be positioned at any desired location on the first section and second section respectively.
  • the location of each of the fluid outlet and fluid inlet on the respective sections will influence the configuration of the linking inlet and linking outlet of the connector.
  • the fluid inlet and corresponding linking outlet is positioned on the first section parallel to the pivot axis at a radius V away from the pivot axis.
  • This fluid outlet orientation dictates that the corresponding linking inlet is configured to follow the path of an arc of radius Y centred about the pivot axis so to allow a fluid connection to be maintained between the linking inlet and linking outlet at all the positions that the fluid inlet must be located relative to the fluid outlet.
  • the fluid inlet be rotatable a full 360° about the pivot axis relative to the fluid outlet, then the corresponding linking inlet (and/or linking outlet) would follow a circular path of radius V having a centre at the pivot axis.
  • the fluid inlet and/or fluid outlet could be position perpendicular to the pivot axis or any angle therebetween.
  • a fluid tight seal can be maintained between the two sections of the connector by forming a tight seal between these sections. This can be achieved by using a fastener to secure and seal the two sections together.
  • the fastener is located along the pivot axis of the connector.
  • a sealing body such as a sealing washer or the like is included between the first section and second section to enhance the seal between these two sections.
  • the connector can be used for any application where it is desirable to rotate a fluid inlet a selected angle away from a fluid outlet while maintaining a fluid connection between a fluid inlet and fluid outlet.
  • the fluid connector of the present invention is incorporated into a handpiece of an oxy-acetylene cutter.
  • the fluid connector is used to connect the gas supply to the flame fluid outlet of the cutter through a handpiece, thereby allowing the flame fluid outlet of the cutter to be positioned at a desired angle relative to an axis of the handpiece of the cutter while maintaining gas supply to the flame.
  • the fluid connector is used for angled adjustment of water conduits, gas conduits and other such fluid conduits.
