A gear pump assembly includes a drive gear having a plurality of circumferentially spaced teeth, and a driven gear likewise having a plurality of circumferentially spaced teeth positioned for intermeshing engagement between the drive and driven gears via the teeth. A bleed mechanism directs carryover fluid from a discharge side of a bearing dam to an inlet side of the bearing dam in order to supply the carryover fluid to a carryover volume disposed between mating drive gear teeth and driven gear teeth. The bleed mechanism including a passage communicating with at least one of (i) a gear face of the drive gear, (ii) a gear face of the driven gear; or (iii) a bottom of a gear tooth profile adjacent a root region between adjacent gear teeth.

Pump with bleed mechanism for reducing cavitation

A radial piston device includes a housing, a pintle attached to the housing and having a pintle shaft, a rotor rotatably mounted on the pintle shaft and having cylinders, pistons displaceably received in the cylinders, and a drive shaft coupled to the rotor and rotatably supported within the housing. The radial piston device includes mechanisms for reducing a pressure loss of hydraulic fluid flowing into the pintle shaft.
