The present invention relates to apparatus for changing the direction of flow of fluids. Apparatus in which this change of direction is extensively practised is that in which textile materials are to be dyed by dye liquor by means of a pump which passes the dye liquor in two directions alternately through the goods, with any desired steam, gas, and water treatment.

In known apparatus for the change of direction as indicated, multi-way cocks are usually employed, the valve being a rotatable body within a casing, this body having axial and radial openings to correspond with various outlets in the casing as the member is moved. This form of distributor presents disadvantages which restrict its use. In the paths for the fluids sharp bends occur, as also variations in the cross sectional areas of such paths, with loss of power and force through friction'and reaction. Further the frictional surfaces are large and this with the form of valve tends to seizing. This danger is enhanced by the pressure and suction action of the pump or other fluid circulating medium, as well as by the flow of the fluid itself, which gives unequalreaction within the valve, thus increasing the difliculty of operating it: if indeed it does not cause it to seize altogether. Corrosion also occurs and, with iron valves working with acid liquids, at an early stage, with the resultant necessity of frequently disassembling and cleaning of the parts. Also the complicated form of the valve body favours the alternate expansion and contraction of the parts under the varying temperatures of boiling and cold water. employed 35 in the treatment of textile materials, with deformation of the parts and a still further addition to the danger of seizing.

A still further disadvantage with this form of distributor or valve is that on a sudden change 40 of direction of flow of liquid therethrough the sudden closing of the opening through which the liquid has been passing under pressure causes reaction in the current with consequent knocking in the pipe.

The object of the present invention is to provide a multi-way valve in which all these disadvantages will be eliminated, and-for this purpose the invention consists in a valve casing, openings and pipe connections in and upon such casing, and a combined plate and pipe rotatable within the casing, these two being at an angle to each other so that by their movement together given pipe connections and openings may be put into communication with each other or obturated. Such a form of valve gives the greatest simplicity -to the outer side of this container.

whilst affording two or more directions of flow; a minimum area of frictional surface, free flow of the liquid without sharp bends and changes of cross-sectional areas of liquid passages; and immunity from seizing as a result of changes of 5 temperature of liquids employed.

The invention in a practical construction will now be described by way of example as shown in the drawing annexed. In this drawing:

Figure 1 is a sectional view of an apparatus for the treatment of textile materials. the valve which is the object of the invention being incorporated therewith;

Figures 2 to 5 inclusive are section views similar to that of Figure 1, with different positions of the valve;

Figure 6 is a cross section of the valve itself;

Figure 7 is a vertical section of the valve body according to Figure 6 and a side view of the sectioned rotary body.

On the container I of the treatment apparatus a casing 2 is cast or bolted. The valve, Figures 6 and 7, consists of a curved surface 4 and the curved pipe 5 which passes therethrough and is combined therewith. The plate is journalled in bearings 6 and I and a handwheel 8 is provided, which passes through a stufiing box 9. The pipe blocks and openings in the casing 2 are perpendicular to the axis and arranged in a radial plane. The opening l0 leads to the inside of the container or goods carrier as shown; the opening II On the block 12 is a pump connection I3 with valve or cook I4 closing this to the fluid tank l5.

0n the block I6 is secured a bent suction pipe l'l, into which an overflow and additional supply pipe 18 opens and on which is a water supply pipe 20 with valve IS. The pump 2| is connected to the block 22. The block 23 serves for access of a steam, compressed air, gas and air suction pipe with the valves 24, 25, and 26, as well as a connection to an outlet 21. The overflow with valve 28, on the closable cover 29, completes the apparatus.

After the goods have been charged in the container and the cover 29 closed, valve II is opened and liquid enters the container from tank l5. If the latter is under the floor, the pump 2| draws it as seen in the position of Figure 1 through the pipe IS, the opened valve ll, block l2 and suction pipe I! and forces it through the block 22 round the circular bent pipe 5 the cross sectional surface on both sides of the pipe being approximately the same as the cross sectional surface of the block 22. The liquid is forced through opening In into the interior of the goods carrier,

and passes from the inside to the outside of the same. This continues until it is seen that full overflow is taking place through 28. Valve I4 is then closed and the valve adjusted according to Figure 2. The liquid is now pressed through the material from the outside to the inside thereof, as indicated by the arrows. After a determined period the valve is adjusted either by hand or by any known automatic means, according to Figure 3. The duration of pressure in either direction can be so arranged that the treatment from inside to outside of the goods, and vice versa, is equal. As a result of the formation of the valve 45 with a very narrow frictional edge there is no blocking of liquid or knocking; the stream of liquid from the block 22 finds no resistance in its path and is smooth and even without loss of force, as the cross sectional area of the path of flow is equal at all times. After treatment as described is completed the liquid is run off to storage tank or pumped to a tank as seen in Figure 4 wherein, as indicated by the arrows, the liquid is drawn from the interior and the exterior of the goods simultaneously, with simultaneous sinking of the liquor levels.

After this textile goods are generally treated by suction to remove superfluous liquid therefrom. For this purpose the valve stands in the position indicated in Figure 5. Through opening of the valve 26 air passes to force by cover 30 the liquid from outside to inside of the material.

The valve is in a similar position if the goods before the begirming of liquid treatment are to be wetted out or moistened by steam, or treated with compressed air or gas for the purpose for example of oxidation. The directions of flow for these purposes are exactly reversed as indicated. After the removal of the superfluous liquid for the purpose of re-use the rest is rinsed out. The valve for this purpose is in the same position as in Figure 1. Rinsing water valve I 9 and outlet valve 21 are opened and the pump forces water from the interior through In and through the material. the water passing through block I21 to 24 and through the outlet 21 into drain.

After rinsing further suction will generally take The position according to Figure 1 permits also that with developing dyestuifs the developing fluid may be supplied by suction and passed speedily by the pump through the material by pressure, whereby the free colloidal compounds of this with the overplus of the dyeing liquor is passed through 21 to drain. When it is een by the outrunning liquid that these are nearly all run out, the valve is quickly adjusted to supply dye liquor from inside to outside and the valve 21 closed.

Only one example is hereinbefore described, but it will be obvious that the principle can be carried out in other ways. The number of connections served by the valve can be more, or less, than that given. Also, by the combination of two valves with appropriate combinations, it will be seen that very many different directions of flow can be obtained.
