Abstract
PURPOSE: To effectively cool oil and to effectively prevent inertial revolution by providing a switching valve and a high pressure relief valve in parallel between the oil hydraulic pressure pump and the cooler which are connected to the transmission rod, and also by providing a low pressure relief valve on the downstream side of the high pressure relief valve.
CONSTITUTION: The oil hydraulic pressure pump 14 which is connected with the cooler 16 is coupled with the transmitting rod, and the switching valve 19, which is closed when the main clutch 9 is broken away, and the high pressure relief valve 21 are provided between the oil hydraulic prssure pump 14 and the cooler 16 in parallel, and at the same time, the low pressure relief valve 22 is fitted on te downstrem side of the high pressure relief valve 21. By this constitution, oil can be constantly circulated to the cooler at the appropriate oil feeding pressure which is determined at the low pressure relief valve 22 no matter what the condition of the switching valve 19 is, and constant and smooth cooling of oil becomes possible. Also, as high oil hydraulic pressure is applied to the oil hydraulic pressure pump 14 when the main clutch is broked away, the transmitting rod can be stopped suddenly and inertial revolution can be effectively prevented.
