Abstract

796,254. Multiple gear pumps. BORGWARNER CORPORATION. July 19, 1956 [July 22, 1955], No. 22401/56. Class 110 (2). In a multiple gear pump at least one of the bushings of each of the driven gears or the adjacent face of each of said gears is provided with a relief recess such as 65 which communicates with a low-pressure zone through a pair of channels 76. Specification 572,967 is referred to.
