Abstract
An integrated pump device forms a module in which a motor, an oil pump rotated by a driving force of the motor, and a hydraulic parking lock actuator are integrally constructed. The hydraulic parking lock actuator operates to switch between an advance state and a retard state by hydraulic pressure supplied from the oil pump, and locks a parking lock mechanism of an automobile in the advance state and unlocks the parking lock mechanism in the retard state. The oil pump can supply oil for cooling or lubrication to an oil consumer via the hydraulic parking lock actuator.
Claims11
An integrated pump device, comprising:
- a motor;
- an oil pump rotated by a driving force of the motor and configured to discharge oil drawn from an oil pan;
- and
- a hydraulic parking lock actuator that operates to switch between an advance state and a retard state by hydraulic pressure supplied from the oil pump, and that locks a parking lock mechanism of an automobile in the advance state and unlocks the parking lock mechanism in the retard state;
- wherein
- the motor, the oil pump and the hydraulic parking lock actuator are integrated to configure an integrated module,
- the hydraulic parking lock actuator is connected to an oil consumer via an indirect supply oil passage, and
- the oil pump is configured to supply oil for cooling or lubrication to the oil consumer via the hydraulic parking lock actuator.
