Abstract
300,443. Hildebrand, W. Feb. 16, 1928. Addition to 247,535. Fluid - pressure. - The connection of the train-pipe to a venting chamber is effected by the graduating valve of the main control valve or of a separate easily movable slide valve operated by the piston of the main valve which also controls the outlet from the chamber to atmosphere, the operation being such that the train-pipe is connected to the chamber by the initial movement of the valve piston and before the closing of the outlet of the chamber by the main valve. As shown in Fig. 1, the venting chamber connected to the port u is normally connected by a passage m in the main valve b to a throttled port o leading to the atmosphere. The initial movement of the piston p of the valve moves the graduating valve a to connect the train-pipe port l to the chamber by the. ports l<1>, n, m. The subsequent movement of the main valve b closes the exhaust port o while leaving open the connection of the train-pipe to the chamber. In a modification, the connection of the train-pipe to the chamber is effected by a separate small slide valve connected to the piston p and disposed on the other side thereof to that of the valves a, b.
