Abstract

885,802. Reciprocating pumps. CINCINNATI MILLING MACHINE CO. Jan. 11, 1960 [July 2, 1959] No. 896/60. Class 102(1). [Also in Group XXIX] A pump piston 25 is directly connected to hydraulic motor pistons 17, 18. The pump may be double acting or may draw through separate inlet valves from separate sources each connected to one end of the pump cylinder.
