PUMP UNIT

摘要

PROBLEM TO BE SOLVED: To provide a pump unit capable of reducing a cost and capable of improving assembling efficiency in the pump unit having a charge mechanism for replenishing pressure oil. SOLUTION: This pump unit having a pump case for housing a hydraulic pump and a center section connected so as to block up an opening of the pump case, has a first oil feeding valve for allowing the inflow of oil to a pair of suction/delivery passages from a first charge oil passage and preventing the outflow of inverse directional oil, and is constituted so that the first oil feeding valve can be installed from an abutting surface of the center section or an abutting surface with the center section in the pump case.
