Abstract

647,259. Distributing valves. JOY MANUFACTURING CO. Aug. 8,1947, No. 22056. Convention date, Jan. 26, 1940. [Class 122(ii)] A hammer piston fluid pressure motor has its distributing valve in two parts 29, 30 which control fluid supply to the rear and front ends of the cylinder respectively through ports 44 and 42. The valve parts are moved by cushioning and live air admitted to act on the valves by the passage 47. The two parts of the valve contact one another during part of the working cycle ; and control air flow by flanges 39, 40 and restricted passages 60, 61. In the form shown, Fig. 6, the two parts of the valve are telescopic one in the other but are of overall sizes such that operation is equally maintained if inserted end for end during assembly. In a modification the two valve parts are identical and contact end to end. In further modifications throwing passages from each end of the cylinder are separate.
