Abstract
284,347. Chicago Pneumatic Tool Co., (Assignees of Moody, J. C.). Jan. 28, 1927, [Convention date]. Check lift valves; seats; buffers. - In non-return valve units of the spring- loaded plate type for pumps, compressors, &c. comprising a seat 5, a guide keeper 15, and a loading spring 17, the opening movement of the valve is cushioned by buffer means in the form of a concentric heavy coil spring 18 enclosing the loading spring 17 and normally out of contact with the valve, as shown. The spring buffer is frictionally supported within fingers 15e depending from the radial head 15b of the keeper. The valve unit is held yieldingly in place by a heavy spring 13 enclosed by a cover 7 which carries a. central set screw 11 which may also be used to clamp the valve unit in position.
