摘要

The control device of pressu00e7o and alimentau00c7u00e7o fuel. A control device enabling the easy setting of a pressure opening pressure of vu00e1lvulo and having a pressure gradient is small when a flow is small.A pressure regulator (10) includes a ball (31), a part of the seal (35) closing a passage of the flow when the ball (31) for the part of the seal (35), and a retainer (33) allowing the other end of the spring valve (32) to contact it and capable of changing a force of energizing by mol The valve (32).The retainer (33) is arranged in a valve chamber (34) to form movable along the direction of flow passage. The force of energizing the spring valve (32) can be accurately adjusted by moving the retainer (33) to change the setting of alura spring valve (32).Since a part with spring property in the device only is the spring of the valve (32), the opening pressure of the valve can be adjusted easily and its dispersion can be suppressed.
