DEVICE FOR CONTROLLING THE PASSAGE OF A FLUID Filed June 5, 1947 I closing member.

Patented Aug. 18, 1953 DEVICE FOR CONTROLLING THE PASSAGE OF A FLUID Pierre P. Honegger, Geneva, Switzerland Application June 3, 1947, Serial No. 752,077 In Switzerland June 13, 1946 14 Claims. 1

The present invention relates to a device for controlling the passage of a fluid of the type comprising a member presenting a passage and a member for closing this passage.

The device according to the invention is characterized in that at least one of these two members is grooved in the direction of the flow of the fluid.

The annexed drawing represents, in the way of examples, various embodiments of the device to which the present invention relates.

Figure 1 is a large-scale axial section of a first embodiment;

Figure 2 is a plan of the seat of the same embodiment;

Figure 3 is an axial section of the second embodiment;

Figure 4 is a plan of the seat of the second embodiment;

Figure 5 is an axial section of an alternative form of closing member; and

the member I presents at the outlet end of the passage 2.

As is seen in the drawing, the surface of the passage 2 is grooved, the rectilinear grooves 6, extending from the inlet end I of the passage 2 v right to its outlet end 8 against which the closing member 3, 4 comes to bear for closing the passage. As is seen, the outlet end of the passage 2 constitutes a surface forming a seat for the This surface presents a fiat annular portion 9 in which the grooves termi nate, the width of this portion 9 being equal to the depth of these grooves, as Figure 2 shows. This width may be slightly larger than the said depth. The circular ridge marking the intersection of the flat annular surface 9 and the truncated-cone-shaped surface 5 is indicated at III.

In the embodiment according to Figure 3, the closing member 3 also presents a joint 4, but it is further fitted with a, shaped teat I I which fits into the passage 2 when the latter is being closed. The member I consists, in this second embodiment, of a piece which screws on to the body (not shown) of the device. The passage 2 includes an inlet part I2 which gradually tapers a 2 and a narrowed cylindrical part It extending from the neck M to the outlet end 8 of the passage 2.

In this second example, the grooves 6, which are rectilinear, begin beyond the entry neck I I of the passage; they extend, as in the first embodiment, right to the outlet 8. The outlet end of the passage terminates in a face forming a seat for the closing member, this face consisting of two truncated-cone-shaped surfaces, the outer one 5 being convex and the inner one I5 being concave. The circular ridge of intersection of these two surfaces 5 and I5 is indicated at IIS. The bottom of every groove terminates flush with the intersection I 6 of the outlet end B.

It has been observed that, by providing grooves running in the direction of the flow of the fluid, as has been described with reference to the previous two embodiments, the whistling noise which is generally produced when ordinary similar devices are functioning and the fluid is flowing through the passage 2 is practically completely eliminated. The flow of fluid is divided by the grooves into fine streams and the vibrations, if any, of these streams are out of phase so that any noise due to these vibrations is effectively minimized and practically prevented.

In Figure 5, a closing member similar to the one shown in Figure 3 has been represented but it difiers from the latter in that the teat II presents grooves I'I running in the direction of the flow of the fluid.

The closing member according to Figure 5 may, in a variant of the examples previously described, be employed with the member I according to Figure l or in conjunction with the member I according to Figure 3.

It will be observed that, in the example ac cording to Figure 5, the grooves extend from the base I8 of the teat II to close to its top I9.

As shown in Figure 6, it may further be provided that the grooves in the passage and the grooves in the teat be helically inclined in opposite directions to one another.

Although the invention has been described for the case Where the seat with which the closing member co-operates presents a conical surface 5 allowing of terminating at the line of closing and to have nevertheless a good closing, the invention is not limited to this case and could also be applied to diiferent types of construction.
