FIELD: motors and pumps.
SUBSTANCE: invention relates to vehicles, and more particularly to hydraulic clutches. Clutch hydraulic system for vehicle comprises mechanical oil pump (17), electrically driven oil pump (18), forward clutch (14), and control valve unit (19). Main pump oil passage (26) leading from mechanical oil pump (17) is connected to control valve unit (19). Sub-pump oil passage (27) leading from electrically driven oil pump (18) is connected to forward clutch oil passage (29), into which oil passage outlet (29a) opens at an inside location closer to the clutch rotation axis CL than clutch oil chamber (28) of forward clutch (14).
EFFECT: simplified design is achieved.
