摘要: An automotive radiator cooling system has a radiator cooling fan driven by a hydraulic motor actuated by a pressurized fluid fed through a hydraulic circuit from an engine-driven hydraulic pump. A bypass line extends in bypassing relationship to the hydraulic motor and has ends connected to the circuit upstream and downstream of the hydraulic motor, respectively. A check valve is provided in the bypass line and is operative to allow a flow of the fluid from a reservoir through the bypass line back into a part of the circuit upstream of the motor only when a pressure drop takes place in that part of the circuit due to free rotation of the cooling fan, and thus of the motor, independently of the drive by the hydraulic pump. The backward flow of the fluid is operative to compensate for the pressure drop to prevent the occurrence of cavitation in the circuit upstream of the motor. Desirably, the bypass line is incorporated into the housing of the hydraulic motor.

摘要: A viscous liquid heater is composed of a housing having a heat chamber filled with viscous liquid, a rotor disposed in the heat chamber and a rotary plate movable to change volume of the heat chamber. The rotor rotates in the heat chamber and shears the viscous liquid to generate heat. The temperature of the heat chamber is controlled by changing volume of the heat chamber.
