Title:
INTEGRATED PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/130672
Kind Code:
A1
Abstract:
This integrated pump device constitutes a module formed by integrating two pumps (20, 30), one motor (10), and hydraulic actuators (60, 70). The two pumps (20, 30) are constituted of an oil pump (30), which is one open flow path pump (a rotary pump that ejects fluid into an open space via any flow path), and a water pump (20), which is one non-open flow path pump (a rotary pump that pumps fluid in a closed flow path). The motor (10) drives both of the two pumps (20, 30). The hydraulic actuator (60) operates so as to switch between a forward state and a return state via hydraulic pressure supplied from the oil pump (30).
