Abstract

22,598. Attwood, W. W. Oct. 20. Drawings to Specification. Steam pumps. - Relates to a valve gear for direct-acting pumping-engines, and consists in providing the steam cylinder with primary and secondary valve-chests within each of which work fluid-actuated slide valves, the primary valve having the usual function of controlling the supply of steam to the cylinder while the secondary valve, which is controlled directly from the main cylinder, regulates the working of the primary valve.
