Title:
INTEGRATED PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/130671
Kind Code:
A1
Abstract:
This integrated pump device constitutes a module in which a motor (10), an oil pump (30) that rotates due to drive force of the motor (10), and a hydraulic actuator (60) actuated by hydraulic pressure supplied from the oil pump (30) are integrally configured. The hydraulic actuator (60) is provided with a housing (61) having one or more vane chambers (621–624), and a vane rotor (63) housed in the housing (61) and provided with one or more vanes (641–644) corresponding to the vane chambers. Advancing-side hydraulic chambers (651–654) are formed on one circumferential-direction side of the vanes in the vane chambers, and returning-side hydraulic chambers (661–664) are formed on the other circumferential-direction side of the vanes. The vane rotor (63) rotates in one direction and goes into an advancing state when hydraulic pressure is supplied to the advancing-side hydraulic chambers (651–654), and the vane rotor (63) rotates in the other direction and goes into a returning state when hydraulic pressure is supplied to the returning-side hydraulic chambers (661–664).
