Abstract
PURPOSE: To automatically raise the temperature of oil, by providing an oil temperature detector to decrease the discharge of a hydraulic pump only when the oil temperature is low.
CONSTITUTION: The temperature of working oil and the degree of opening of a variable throttle valve 8 are proportional to each other. When the temperature of the working oil has reached a prescribed level, the variable throttle valve 8 stops performing the restriction of flow. When the temperature of the oil is low, the degree of opening of the variable throttle valve 8 is also low. At that time, the discharge of the oil from a hydraulic pump 2 is automatically restricted by the valve 8 so that the temperature of the oil rises. When the oil temperature has risen to the prescribed level, the variable throttle valve 8 stops performing the restriction. Therefore, the oil temperature can be automatically heightened.
