Abstract
PURPOSE: To control two pressure reduction valve independant from each other by including a decelerated speed detecting element only in a fluid pressure circuit of one system.
CONSTITUTION: Controlled medium coming from an input entrance 100 of the primary circuit runs into an inertial valve box 101, presses a decelerated speed correction piston 14 to turn a ball cage 12, and inclines a guide face 13. As deceleration ratio increases, the ball seats on a seat 11 to choke a seal room 102 and the inertia valve box 101 so that the control pressure generates in the seal room 102. The pressure coming from the pressure room 201 on the right side and the other pressure 109 coming form the left side are balanced in a cylinder of a valve body 30 of a following valve part and at the center portion of it, pressures left from the pressure room 106 and right from the pressure room 202 are balanced. Right action of the valve body 30 depending on the output of the primary circuit increases the pressure of the secondary circuit a little and the other hand, left action of it generates the pressure at the output exit 203 of the secondary circuit, which follows the pressure of the primary circuit. Then the secondary circuit pressure can be controlled.
