Abstract

534,937. Hydraulic machines, reducing- valves. TOWLER, J. M., and TOWLER, F. H. Sept. 20, 1939, Nos. 26244 and 31364. [Classes 69 (ii) and 135] A piston b effects the traverse of a machine tool or of its work, and itself receives motion from liquid supplied through a pipe e to a branch pipe d leading to one side, and through a valve f and pipe g to the other side in one position of the. valve, while in the other position the pipe g is connected to an exhaust pipe i leading to a meter or choke such as a helical passage of adjustable length. Between the pipe i and the choke a pressure-regulating valve j is provided comprising a hollow ported piston coacting with an inlet annulus q and adjustable by a spring l. Specifications 534,943 and 536,654 are referred to.
