통합 펌프장치는, 모터(10)와, 모터(10)의 구동력에 의해 회전하는 오일펌프(30)와, 오일펌프(30)로부터 공급되는 유압에 의해 작동하는 유압 액추에이터(60)가 일체로 구성된 모듈을 이루고 있다. 유압 액추에이터(60)는, 하나 이상의 베인실(621-624)을 가지는 하우징(61)과, 하우징(61)에 수용되어, 베인실에 대응하는 하나 이상의 베인(641-644)이 설치된 베인 로터(63)를 구비한다. 베인실에서의 베인의 원주방향의 한쪽에 전진측 유압실(651-654)이 형성되고, 베인의 원주방향의 다른 쪽에 리턴측 유압실(661-664)이 형성된다. 전진측 유압실(651-654)로 유압이 공급되었을 때, 베인 로터(63)가 일방향으로 회전하여 전진 상태로 되고, 리턴측 유압실(661-664)로 유압이 공급되었을 때, 베인 로터(63)가 타방향으로 회전하여 리턴 상태로 된다. An integrated pump device is a module in which a motor (10), an oil pump (30) rotated by a driving force of the motor (10), and a hydraulic actuator (60) operated by hydraulic pressure supplied from the oil pump (30) are integrated. The hydraulic actuator (60) includes a housing (61) having one or more vane chambers (621 to 624), and a vane rotor (63) housed in the housing (61) and including one or more vanes (641 to 644) corresponding to the vane chambers. An advance chamber (651 to 654) is provided in an area of the vane chamber in a circumferential direction of the vane, and a retard chamber (661 to 664) is provided in an another area of the vane chamber in the circumferential direction. When the hydraulic pressure is supplied to the advance chamber (651 to 654), the vane rotor (63) rotates in one direction to enter the advance state; and when the hydraulic pressure is supplied to the retard chamber (661 to 664), the vane rotor (63) rotates in the other direction to enter the retard state.
