ABSTRACT:
A pressure regulator includes a case having a fuel inlet port for receiving fuel from a fuel pump, a fuel outlet port for delivering fuel to an internal combustion engine, and an opening. A valve element is attached to an elastic diaphragm that closes the opening. The valve element has a discharge passage for discharging excess fuel by allowing the interior and the exterior of the case partitioned by the elastic diaphram to communicate with each other. A spring seat is provided in the case in face-to-face relation to the valve element in such a manner as to close the discharge passage of the valve element during pressure contact. A spring is also provided for bringing the valve element into pressure contact with the valve seat with a predetermined pressure.
