Abstract
PURPOSE: To simply control the direction, speed, etc. of an actuator by operating a lever at a time and to easily operate a crane in a turning flowing condition, by combining check valves and variable relief valves.
CONSTITUTION: When tilting a lever 9 in the A direction, the set pressure of a relief valve 5 rises in response to the operating angle, pushing force to check valves 42, 44 rises and pressure discharged from a port 22 rises in response to the rise of pushing force. Thus, the speed of the revolution and acceleration of a motor 3 can be controlled by operating the lever 9. When returning the lever 9 to a neutral location, check valves 41, 42, 43, 44 become free, the motor 3 continuously turns by the inertia force of a body of revolution 4 and so-called flowing operation in the turning of a crane can be performed. When tilting the lever 9 in the B direction, the set pressure of a relief valve 6 rises, the check valves 41, 43 are pushed, fluid returned from the motor 3 is blocked and said revolution stops.
