Abstract

PURPOSE: To damper a shock caused by backlash by operating a releaf valve at a low pressure at start to run or at a high pressure in the other operating range.
CONSTITUTION: When a switch valve is turned to start a hydraulic motor, pressurized oil is fed in a branch passage 14 which communicates with a port M1. Passing through a spring room 18 and a communication hole 28, the oil operates a piston 24 to move. Accompanied with the movement, a cound convex 30 passes on a round concave 34. At the time, an orifice 32 is actually cut off and the piston 24 comes in contact with one end of a regulation chamber 22 to stop. Under movement of the piston, the releaf valve 2 decreases in working pressure and after the piston is stopped, the releaf valve 2 functions as a high-pressure releaf valve.
