摘要：
A pump inlet valve includes a valve body and a plunger assembly. The valve body includes a valve body cavity. The plunger assembly is arranged within the valve body cavity and includes a plunger body, a plunger barrel formed at the plunger body so as to form a plunger barrel volume, and a plunger. The plunger is configured to move within the plunger barrel to thereby allow a fluid to flow past the plunger assembly when the plunger is in an open position and to inhibit the fluid from flowing past the plunger assembly when the plunger is in a closed position. The plunger is configured to allow continuous fluid communication between the plunger barrel volume and a supply inlet, through which fluid is supplied to the pump inlet valve.
