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 reducing valves.
CONSTITUTION: When tilting a lever 12 in the A direction the secondary pressure of a reducing valve 8 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 freely be controlled by operating the lever. When returning the lever 12 to a neutral location, check valves 41, 42, 43, 44 become free, the motor 3 continuously rotates by the inertia force of a body of revolution and so-called flowing operation in the turning of a crane can be performed. When tilting the lever 12 in the B direction,the secondary pressure of a reducing valve 11 rises, the check valves 41, 43 are pushed, fluid returned from the motor 3 is blocked and said revolution stops.
