Title:
OIL PRESSURE MULTIIPROCESSING CIRCUIT
Document Type and Number:
Japanese Patent JPS5493777
Kind Code:
A
Abstract:
PURPOSE:To reduce the number of hoses between the operating part and the actuating part, by means of feeding oil pressure signal for operation different in turn stepweisely in a single hose. CONSTITUTION:If a control valve 4 is changed over to c position, the exhausted pressure from a pump 14 is regulated at 80 Kg/cm<2> by a regulating valve 18, thereby a cylinder 1 actuates by means of being changed over by a pressure actuating valve 21. Then when a control valve 5 is changed over to c position, the control valve 4 is allowed to be returned automatically to a neutral position b and the exhausted pressure from a pump 14 is regulated at 100 Kg/cm<2> by a regulating valve 17, thereby a cylinder 2 actuates by means of being changed over by a pressure actuating valve 22. In this case, the actuation of the cylinder 1 is continuously effected. Next, when a control valve 6 is changed over to c position, the control valve 5 is returned automatically and the exhausted pressure from the pump 14 is sent as it is (120 Kg/cm<2>) and a pressure actuating valve 23 is changed over, and a cylinder 3 is actuated. The actuation of cylinders 1, 2 is continued.
