Abstract

PURPOSE: To select brake power optionally in a brake circuit of an actuator adequate to drive various parts of construction machinery by using a pressure control valve which starts to operate at a hig pressure set value and finishes the operation at a low pressure set value.
CONSTITUTION: A fluid circuit provided with a fluid pressure motor 6 is composed of a switching valve unit II and a brake circuit I. The brake circuit I is composed of the first brake circuit 7a which gives a braking work when the regularly operating motor 6 is stopped and the second brake circuit 7b which gives a braking work when the reversely operating motor 6 is stopped. In this case, the brake circuit 7a (the same for 7b), can be constructed by forming parallel connection of the first pressure control valve 8a which starts its operation at a high pressure set value and finishes the operation at a low pressure set value, the second pressure control valve 9a provided with a higher set value than the above-said high pressure set value, and a nonreturn valve 10a, and discharge sides of these valves 8a and 9a are connected to the inlet side of the nonreturn value 10a via a circuit 13.
