Title:
FLUID PUMP STRUCTURE OF TRANSMISSION
Document Type and Number:
Japanese Patent JP2017161049
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a structure which inhibits hydraulic pulsation to reduce the possibility of erosion caused by cavitation.SOLUTION: A fluid pump structure is formed into a structure where a regulator valve (20) is disposed closely contacting with an oil pump (OP), a discharge port (OUT) of the oil pump is directly connected with a pressure oil inlet (P2) of the regulator valve, and recirculation oil outlets (P4, P6) of the regulator valve is directly connected with a suction port (IN) of the oil pump. Specifically, the fluid pump structure is formed so that a sleeve (21) of the regulator valve is integrally formed with the interior of a pump housing (10), the pump discharge port (OUT) forms a common space with the pressure oil inlet (P2) of a valve, and the pump suction port (IN) forms a common space with the recirculation oil outlets (P4, P6) of the valve.SELECTED DRAWING: Figure 3
