Abstract
A hydraulic pump is configured to mount within an internal receptacle defined by a housing of a hydraulically-powered component of a work vehicle. The pump has a housing defining one or more pump chambers. Each pump chamber communicates with a suction port and an outlet pressure port. Each pump chamber contains a pump assembly having a drive member at a fluid interface between the suction port and the outlet pressure port. The drive member is arranged for co-rotation with at least one power input component extending into the housing through each pump chamber. Rotation of each drive member displaces and pressurizes hydraulic fluid through the pump housing, and, when the pump is mounted within the internal receptacle, through internally ported passages routed through walls of the hydraulically-powered component housing.
