Title:
OPERATING OIL CONTROL SYSTEM FOR VARIABLE SPEED FLUID JOINT
Document Type and Number:
Japanese Patent JPS57167532
Kind Code:
A
Abstract:
PURPOSE:To improve an efficiency and prevent the operating oil from the deterioration thereof by a method wherein the amount of the operating oil is controlled in accordance with the revolving number of an output shaft and the air content of the operating oil. CONSTITUTION:A control mechanism 9 for the amount of the operating oil is consisting of a specific gravity meter 10, detecting the specific gravity of the operating oil discharged from an oil feeding pump 8, a revolving number detector 11, detecting the revolving numbe of the output shaft 4, a flow meter 12, detecting the flow amount of the operating oil containing the air, and a control section 14, equipped with a control valve 13 controlling the amount of the operating oil, a computor or the like. A detecting signal A corresponding to the value of the specific gravity of the operating oil detected by the specific gravity meter 10, a detecting signal B in accordance with the revolving number detected by the revolving number detector 11 and a detecting signal C in accordance with the flow amount detected by the flow meter 12 are inputted into the control section 14, whereby, the control section 14 operates a power loss and an apparent amount of the operating oil containing the air and outputs a control signal D in accordance with the amount of the operating oil to the control valve 13.
