Abstract
PURPOSE: To improve the throttling characteristics of a joining hydraulic circuit capable of switching a plurality of directional control valves by one operating lever by enabling to switch the valves by means of small operating force.
CONSTITUTION: In a joining hydraulic circuit incorporating, for example, two hydraulic pumps 1, 2, an actuator 3 operated by the joined hydraulic oil of the pumps 1, 2, and directional control valves 4, 5 for switching the exhausted hydraulic oil from the pumps 1, 2 to switch the valves 4, 5 by operating a manipulating lever 6, there are constructed a throttle 12 fromed between the valve 5 and the hydraulic motor 3 in the circuit 11 for coupling therebetween to introduce the hydraulic pressures at the front and rear of the throttle 12 through conducts 13, 14 into left and right pressure reciving chambers A, B of the valve 4 to thus switch the valve 4 by means of the different pressure between the front and the rear pressure at the throttle 12.
