PURPOSE:To control the transmission torque finely and widely by providing a relief valve or a pressure regulation valve in the way of a loop for returning the operational liquid delivered from the high pressure side space in the casing to the low pressure side. CONSTITUTION:The secondary pressure of a pressure regulation valve 36 is varied properly to regulate the transmission torque from a motor A to an agitator to desired level. When operating said valve 36 in correspondense to the required capacity of the agitator (c) to control the transmission torque from the motor A to the agitator (c) while slipping the casing and shaft relatively, the loss work can be prevented effectively resulting in the energy save effect. |
