  • Power driving device
    Patent number: 6460669
    Abstract: A power driving device comprises a fluid coupling operated by an engine, a wet-type friction clutch disposed between said fluid coupling and a transmission, and a fluid operation means for circulating the operation fluid through said fluid coupling and for feeding the operation fluid to the wet-type friction clutch. In the pump housing of the fluid operation means, there is disposed a hydraulic pump that works as a source of hydraulic pressure, there are formed passages for communicating said hydraulic pump with said fluid coupling and with said wet-type friction clutch, and there are disposed a relief valve for adjusting the pressure of the operation fluid blown out from the hydraulic pump, a control valve for changing over the passage communicated with the fluid coupling and a control valve for changing over the passage communicated with the wet-type friction clutch.
