Abstract

PURPOSE: To widely improve a controllability and workability of the turn unit when operated, by controlling a main control valve of compound check valve type with a variable pressure reducing valve in which the set pressure can be varied by an operation of lever.
CONSTITUTION: A main control valve 2 of compound check valve type and a variable pressure reducing valve 8, 9, in which the set pressure can be varied by operation of a lever 10, are combined. In this way, with the lever 10 operated in the direction, for instance, of an arrow mark A, as shown in the drawing, a feed pressure, from a second port 21b to a motor 4, can be adjusted in accordance with an operating angle of the lever 10, causing this lever operation to freely enable a control of rotary torque and accelerating speed and time of a turn unit 5, further to transmit the torque of the turn unit 5 directly to a feeling of the operator's hand through the lever 10 from the first variable pressure reducing valve 8. Accordingly, controllability and workability of the turn unit 5 can be widely improved when operated.
