Patent ID: 7275372

Claim:
Pressurized hydraulic fluid feeding structure, which is applied to a working vehicle including an HST interposed in a transmission path from a drive power source to a driving axle, comprising: a charge pump having a charge pump body operatively connected to a pump shaft of the HST; and a plate interposed between the charge pump and the HST; wherein the plate is provide with an inlet line that receives pressurized hydraulic fluid from the charge pump body, a pressurized line for replenishment and a pressurized line for hydraulic device that are branched from the inlet line via a branching portion, and a valve for setting the pressure of the pressurized line for replenishment; and wherein the pressurized line for replenishment opens to a contact surface with the HST so as to fluidly communicate with a charge line of the HST, and the pressurized line for hydraulic device opens to an outer surface so as to supply operational fluid to a hydraulic device provided at the working vehicle.
