cH Ecx VALVE TRUcTuRE Filed April 14. 1930 Patented June 23, 1931 UNITED STATES PATENT OFFICE FAR-NHAM YARDLEY, OF WEST ORANGE, NEW JERSEY, ASSIGNOR TO JENKINS BROS.
'OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY 7 CHECK VALVE STRUCTURE Application filed April 14,
The invention relates to check valves of the'general type shown in my prior application Serial No. 397,685, filed October 5, 1929, in which the valve disk is associated with a floating guide, vwhich is traversed by the stem on the back of the valve disk and is held in engagement with an abutment on the valve casing by the usual valve spring, the present invention having for its object the adaptation of the same general structural and operative principles to a valve in which the inlet and outlet openings are angularly disposed.
The invent-ion is illustrated in the accompanying drawings, in which 2 Fig. 1 is a sectional elevation of the complete check valve structure.
Fig. 2 is a horizontal section on line 2-2 of Fig. 1.
Referring to the drawings, 1 indicates the valve casing having an inlet opening 2 and an outlet opening 3 disposed at right angles to the inlet. The portion of the casing in axial alignment with the inlet opening 2 is provided with an opening at internally threaded, so that, in its general form, the valve casing is much the same as a T-coupling.
Formed integrally with the casing is a partition 5 extending transversely of the inlet and provided with the usual port having a beveled valve seat 6, with which cooperates the valve disk 7 having the guide lugs or feathers 8 on its face, which engage the walls of the port or opening and serve to guide the disk in its movements to and from its seat. The back of the disk is provided with a stem 9 surrounded by a helical spring 10, which latter serves to force the disk to its seat and to maintain a fluid-tight seal between the disk and the seat, when the valve is closed.
Fitted in the threaded opening 4 is a cap or closure 12, which includes a rim 13 eX- tending within the valve casing and constitutes an abutment for a floating guide plate 15, which is centrally perforated to receive the stem 9 of the valve disk and is held in engagement with the rim 13 by the helical spring 10. The rim 13 is spaced from the body of the cap 12 by means of lugs 14, which 1930. Serial No. 444,318.
provide openings to permit the ready circulation of fluid about the rim 13 and prevent the formation of a pocket in the cap structure.
It will be noted that the guide plate 15 is capable of limited lateral movement with respect to the annular rim 13, which it abuts, but will serve to guide the valve disk in its movements and permit the disk to adjust itself to any necessary position to insure a sealing fit with its seat.
WVhat I claim is:
1. A check valve structure, comprising a V casing having angularly disposed inlet and outlet openings, an intermediate valve seat, and a third opening parallel with the valve seat, a valve disk having guide members on its face cooperating with the seat and a stem on its back, a screw cap closing the third opening and having a rim extending within the casing, a floating guide plate slidably en-v gaging said rim and traversed by the valve stem, and a spring surrounding the stem and engaging said guide plate.
2. A check valve structure, comprising a casing having angularly disposed inlet and outlet openings, an intermediate valve seat, and a third opening parallel with the'valve seat, a valve disk having guide members on its face cooperating with the seat and a stem on its back, a screw cap closing the third opening and having a circular rim supported by spaced lugs extending within the casing, a floating'guide plate engaging said rim and traversed by the valve stem, and a spring surrounding the stem and engaging saidguide plate.
In testimony whereof I affix my signature.
FARNHAM YARDLEY.
