ACCELERATION SENSITIVE TYPE PRESSURE CONTROL VALVE

Japanese Patent JP3353389

B2

PURPOSE: To quickly control the internal pressure corresponding to acceleration in a supplied body by providing a weight displaced according to the acceleration and a poppet interlocked with the weight so that a supply path between an exhaust port and outlet port and an exhaust path between the exhaust port and outlet port are opened and closed.
CONSTITUTION: A weight 9 displaced according to acceleration and poppets 7, 8 interlocked with the weight are provided. A supply path between an inlet port 10 connected to a high pressure gas source 4 by poppets 7, 8 and an outlet port 11 connected to a body 3 supplied with high pressure gas is opened, and an exhaust path between an exhaust port 12 and the outlet port 11 is closed in the increase of acceleration. In the reduction of acceleration, the action of opening and closing the inlet and outlet ports are inversed. In the supply of high pressure gas to the supplied body, the gas pressure acting on pressure receiving parts 21, 22 is increased in proportion to the increase of an acceleration increasing rate to enlarge the opening of the supply paths of the poppets 7, 8 interlocked with the pressure receiving parts 21, 22, so that the internal pressure in the supplied body is quickly increased.
