HYDRAULIC CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/004407
Kind Code:
A1
Abstract:
The present invention addresses the problem of suppressing an increase in pressure in a hydraulic circuit. In order to solve this problem, this hydraulic circuit has: a first oil path that links to a discharge port of a first oil pump; a second oil path that links to a discharge port of a second oil pump; a hydraulic control circuit in which a first regulator valve is disposed downstream of a confluence point of the first oil path and the second oil path; a third oil path that connects a suction port of the first oil pump and a strainer; a check valve that is provided to the third oil path and restricts movement of oil toward the strainer side; and a relief valve that is provided to the third oil path and discharges oil in the third oil path to the outside when the pressure in the third oil path exceeds a reference pressure.
