Abstract

548,029. Valves. E. M. B. CO., Ltd., and CATLIN, L. A. July 28, 1941, No. 9544. [Class 135] [Also in Group XXII] In a die-casting machine having an injection plunger operated pneumatically, the movement of the plunger is controlled, during the injection stroke and, if desired, during the return stroke, by means of a piston g connected by its rod h, to the plunger and having one or each end of its cylinder connected to a liquid reservoir 3 by a passage k having an adjustable valve n and a non-return valve w as described in Specification 541,083, [Group XXVI]. The passage u of the valve has a groove 2, Fig. 3, and at the other end a tapering groove 4 to prevent it from being choked and is adjusted by a handle r.
