Abstract

The present invention relates to a high-pressure fuel supplying pump, 5 comprising: a barrel formed with a fuel feeding port, a plunger hole and a receiving chamber which communicate with each other; and a plunger which is able to reciprocate in the plunger hole, wherein installed in the receiving chamber are an inlet valve body and an valve holder which abut hermetically against each other, an input fuel passage is formed in the inlet valve body so as to communicate the fuel 10 feeding port with the plunger hole, a pressure chamber communicating with the plunger hole is formed at an end of the valve holder contacting with the inlet valve body, an inlet valve core is disposed in the pressure chamber, the inlet valve core is matable with the inlet valve body so as to define a first sealing interface therebetween, and the first sealing interface is openable or closable such that it 15 allows the input fuel passage selectively to communicate with the pressure chamber or to isolate from the pressure chamber, and wherein an output fuel passage is formed in the valve holder to communicate with the pressure chamber, and the valve holder is provided in such a way that it allows the output fuel passage selectively to communicate with the pressure chamber or to isolate from the 20 pressure chamber.
