Abstract

PURPOSE: To have an accurate and secure sensing of load and enhance reliability by actuate a plunger with the load spring effect when the load is over a certain value and by driving the poppet of a valve through this action of plunger.
CONSTITUTION: A shutoff valve 10 is composed of a valve chamber 14 and a plunger chamber 15. In the chamber 14 an air intake 16 and an air outlet 17 are provided, and a valve port 18 is provided between the intake 16 and outlet 17. A bleed poppet 19 to open and close this port 18 is so installed as to be placed on the port 18 with a spring 20. A plunger 21 is installed in the chamber 15 to drive this poppet 19, where one end extends to outside the housing 11 penetrating the poppet 19. The plunger 21 is energized leftward by a spring 25 which shall be deflected when the load exceeds a certain value. When load is applied to one end of the plunger 21 directed to the right and exceeds said specified value, the plunger 21 will move to the right to drive the poppet 19, and the intake 16 and outlet 17 are thus put into communication.
