Beschreibung
Zusammenfassung:	PURPOSE: An oil pressure feeding device for a vehicle is provided to minimize a load due to a variable displacement pressure pump when starting an engine. CONSTITUTION: An oil pressure feeding device for a vehicle includes a variable displacement pressure pump (100), a cut-off control valve (200), a first oil pressure pipe line (310), a second oil pressure pipe line (320), a third oil pressure pipe line (330), and a switch valve (400). The pump is driven by the engine or motor of the vehicle, and feeds a working fluid to multiple required regions inside the corresponding vehicle. The pump has a swash plate (110), a first moving cylinder (120) connected to one end of the swash plate, and a second moving cylinder adjusting the tilt angle of the swash plate. The pump is actuated by oil pressure. The cut-off control valve is selectively manipulated according to the pressure of the working fluid from the pump, and controls the second moving cylinder to move. The first oil pressure pipe line feeds the working fluid from the pump to the cut-off control valve. The second oil pressure pipe line feeds the working fluid from the cu-off control valve to the second moving cylinder.
