Abstract

PURPOSE: To reduce override pressure in a direct-acting relief value by a method wherein an outer collar is provided on the valve body so as to induce and transform the fluid jetted through an open valve almost into the outer diametrical direction.
CONSTITUTION: When the pressure of a main circuit 4 reaches a set value, the pressure is transferred from a main passage 5 to lift the valve body 10 which separates from a valve seat part 9 against the resilient force of a member 11. As the result of it, a circular clearance part 22 is formed and fluid is jetted in the inclined direction to the axis as indicated by the arrow C. Said jetted fluid is induced and the flow is transformed by the outer collar 16 to the outer diametrical direction as shown by the arrow E and then is returned from a release passage 8 and a release circuit 7 to a tank 6. When the outer collar 16 is provided on the valve body 10 in this manner, the jetted fluid is induced and the flow is transformed into the outer diametrical direction E.
