Abstract

618,104. Check valves. FINNEY PRESSES, Ltd., and MOORE, G. E. Oct. 19, 1946, No. 31141. [Class 135] A pre-filler valve for hydraulic presses comprises a non-return valve 5 having a seat in the form of a spring-loaded slidable sleeve 4 having a shoulder 8 which with the surrounding valve casing 1 defines an annular chamber 9 containing a spring 11 and connected by ports 10 with the inside of the sleeve. The valve may also be operated manually at any time by a handle on a spring-loaded stem 15 attached to a piston 12 bearing another stem 7 which engages a recess 5a in the valve 5. The sleeve 4 which has packing rings 4a prevents chatter or hammer of the valve by cushioning its return movement. The valve head 5 has guide fins 6.
