Abstract

345,203. Regulating hydraulicallyactuated mechanism. SOC. ANON. DES ETABLISSEMENTS CUTTAT, 53, Rue Servan, Paris. Dec. 4, 1929, No. 37145. Convention date, July 17. [Classes 69 (ii) and 135.] In order to keep the speed of a piston Q, Fig. 1, constant despite variations in the load, the exhaust conduit is throttled at 11, and the inlet conduit 5 controlled by a valve 1 acted on by a counterweight or spring 2 and at 9 by the exhaust pressure. Bypass and reversing valves 13, 15 may be provided. In a modification, liquid may be supplied when necessary through a pipe 19, Fig. 2, and valve 18, and the exhaust conduit is throttled by a series of perforated discs 14, and by a groove 20 in the valve 1.
