Abstract

745,600. Reciprocating pumps. DOWTY HYDRAULIC UNITS, Ltd. Nov. 17, 1954 [Nov. 17, 1953], No. 31871/53. Class 102(1). [Also in Group XXIX] Two plunger pumps each draw liquid from a reservoir 13 and are selectively operated according as a hand lever 24 is rocked in one direction or the other from its mid-position. In the mid-position of lever 24 the plungers 18 are spring-urged to a central position in which their cylinders communicate with the reservoir through bores 25, 27 in the plungers.
