May 11, 1943. H. ,w. GOETZ VALVE Filed Oct. 12, 1940 Patented May 11, 1943 VALVE Herbert W. Goctz, Alhambra, Calif., assignor to Patent Royalties, Inc., Huntington Park, Calif., a corporation of California Application October 12, 1940, Serial No. 360,932
4 Claims.
My invention relates to a valve assembly of the type in which the valve member is capable of circumferential shifting and rotating so that at each closing of the valve a different contacting surface of the valve will engage the seat. Such type :of valve is shown in the patent to Gerhard Meyer, entitled Pump valve, No. 1,939,- 128, issued December 12, 1933, the patent to John J. Ferlin and Herbert W. Goetz for Valve, No. 1,940,999, issued December 26, 1933, and the patent to John J. Ferlin and Herbert W. Goetz for Valve, No. 1,942,417, issued January 9, 1934.
It is an object of my invention to provide a valve assembly of the general character disclosed in the patents mentioned above in which the guiding and centralizing mean for the valve cooperates between the valve and the seat so that it is unnecessary to have any parts of the pump in which my invention is installed, specially designed or prepared for the reception of the valve of my invention.
It is a further object of my invention to pro- Vide a valve structure in which the valve is provided with a guide sleeve which is closed at the top and opens downwardly through the bottom of the valve and in which there is positioned within the guide sleeve a centralizing ball which is carried by a support which-extends upwardly into the guide sleeve. In the preferred form of my invention, the centralizing ball is supported on a stem which is carried by a spider formed on the seat.
It is a further object of my invention to provide a valve assembly having the features and advantages set forth above, which is of simple and sturdy construction, which i economical to construct, and which may be easily installed in a pump without danger of misplacement .or misalignment of any of the parts.
-Other objects and advantages of my invention are contained in the details of construction of the preferred form of my invention and will be pointed out during the course of the following detailed description.
Referring to the accompanying drawing in which the preferred form of my invention is illustrated:
Fig. 1 is a sectional view through the valve of my invention, the valve being illustrated in position within a pump.
Fig. 2 is a fragmentary view partly in section taken on theline 2-2 of Fig. 1.
Referring to the drawing in detail, Fig. 1 shows a valve chest having a wall II which supports a seat l2, the seat I2 being threa'dedly or otherwise secured in place. In an outer wall Id of the pump there is an entrance opening !5 through which the valve assembly may be inserted and removed, this opening [5 being closed by a suitable cover I6.
Referring now more particularly to the valve assembly of my invention, the seat 42 is provided with an arcua-te seat surface 26 which is preferably semi-spherical and i preferably generated around a point 2| which in turn is preferably located on the axis A-A of the seat opening 22. Supported in the seat 12 is a spider consisting of arms 23 and a central hub 2t. Carried by the hub 26 is a stem or support 25 having a centralizing ball or spherical guide element 26 supported at its upper end. The stem 25 is preferably removably supported by the hub 24 by threaded engagement 2?, as illustrated. The centralizing ball 26 has an arcuate surface 29 which is preferably semi-spherical in shape and is preferably generated around the point 2! The ball 26 is provided with drainage slots 38.
The valve 32 of my invention has a valve part 33 which provides an arcuate valve surface E l which is preferably semi-spherical and is preferably formed on a radius of the same length as the radius on which the valve surface it: is formed, so that when the valve 32 is in seated position with the valve surface 3 2, contacting the seat surface 20, as shown in Fig. l, the point around which the valve surface it is formed will coincide with the point 2|. When the valve is in a seated position as shown, the radiuses B, C, and D all project from the point 2i.
The valve 32 provides a guide means in the form of a sleeve 36 closed at its top by an end wall 31. The inside of the sleeve 36 provides a cavity which is closed at its top but whichcpens downwardly through the bottom of the valve part 34. The sleeve 35 provides an inner guide sur-- face 39 which is preferably cylindrical and is preferably of a diameter twice the radiu C so that there will be a relatively accurate aligning cooperation between the 'ball 25 and sleeve 35. It is possible to make the cross-sectional shape of the sleeve 36 other than cylindrical and still obtain the action between the sleeve and ball which. will be pointed out hereinafter. It appears desirable under such alternative construction to have opposing walls parallel to each other and spaced equally on opposite sides of the center line of the valve 32.
In operation the valve engages the seat when in closed position with the arcuate surfaces 20 and 34 in contact with each other. When the valve is opened, the valve moves upwardly and the upper end of the sleeve 36 or the end wall 31 may engage a wall 40 of the cover l6, thus limiting the upward movement of the valve. It will be seen that the cooperation between the sleeve and ball allows the valve to move upwardly or downwardly along the axis A-A, allows the valve to rotate, and, furthermore, allows the valve to oscillate or shift circumferentially. The arrangement provided permits gyratory motion of the valve but the parts are so constructed and arranged that regardless of the shifted position of the valve when the valve moves downwardly and is in a position to engage the seat l2, the center of the arcuate surface 34 will be on the axis A-A and the point around which the surface 34 is generated will coincide with the point 2| around which the surface 20 is generated.
In installing the valve assembly of my invention the valve and seat and guide means constitute a unitary structure which is entirely independent of all other parts of the pump structure in which the valve may be employed. Obviously, if desired, only the valve need be replaced or if the ball 26 has become worn it can be replaced by unscrewing it from the hub 24.
In the foregoing description I have described the preferred form of my invention. It should be understood, however, that various alterations and modifications may be made without departing from the spirit and scope of my invention, as set' forth in the statement of invention and appended claims.
I claim as my invention:
