摘要： A hydraulic power transmission is provided with a frictional engagement element as a lock-up clutch between a hydraulic power transmission chamber, housing a pump impeller and a turbine runner, and a servo oil chamber of the lock-up clutch. A lock-up oil passage that supplies lock-up hydraulic pressure to the servo oil chamber is connected to a hydraulic pressure supply circuit that is used in common with a circulation oil passage that supplies hydraulic pressure for circulation to the hydraulic power transmission chamber. An orifice is disposed in the circulation oil passage. It is thus possible to perform lock-up with different supply pressures. A common oil supply for the lock-up oil passage and the circulation oil passage is provided, for example, by disposing a converting circuit that adapts an oil passage connection to hydraulic transmissions with different types of lock-up clutches.
