Abstract

671,675. Gear pumps. THOMAS HYDRAULIC SPEED CONTROLS, Inc. April 27, 1949 [Nov. 16, 1948], No. 11214/49. Class 110(ii) [Also in Group XXIX] In a gear pump which forms part of an hydraulic variable speed coupling (See also Group XXIX) the ends 40b of the inlet channels 40 of the pump and the ends 41b of the discharge channels 41 of the pump are enlarged to substantially the full width of the pump body. The series of inlet openings 40a for the intake ports 40 and the series of outlet openings 41a for the discharge ports 41 are located on opposite ends of the pump body and the inlet opening 40a of an intake port 40 for each planet gear cavity 38 is axially aligned with an outlet opening 41a of a discharge port 41 of an adjacent one of the planet gear cavities and such axially aligned intake and discharge openings are located midway between and communicate with opposite sides of cavities for two of the planet gears.
