Claims

[Scope of utility model registration request]

A valve body with two input/output ports, a pair of glue tongue seals arranged symmetrically on the same axis inside this body, a plunger that abuts the valve head against these seals to reduce pressure, and a plunger inside the valve body. It consists of a piston that is inserted into the cylinder and fluid-tightly guides the rear end of the plunger, and a set spring that is interposed between the retainer that engages the moxibustion plunger and biases each plunger in opposite directions. In the event of a failure in the hydraulic circuit, the piston is deflected to the failed side and the movement is transmitted to the plunger in the normal circuit, allowing the valve head of the plunger to pass through the lip seal. In the regulating valve, fix the spring retainer to the plunger,
A two-system controlled dynamic hydraulic pressure regulating valve characterized in that the movement of the piston is transmitted to the plunger via the retainer.
