ABSTRACT:
A high pressure pump draws fluid from a fluid inlet into a compression chamber through an inlet chamber. The high pressure pump has a fluid chamber that communicates with the fluid inlet via the inlet chamber. The high pressure pump includes a plunger and a cylinder. The plunger draws fluid from the inlet chamber into the compression chamber when the plunger moves in a drawing direction. The plunger is capable of pressurizing fluid in the compression chamber when the plunger moves in a pressurizing direction. The cylinder movably supports the plunger therein. When the plunger moves in the drawing direction, fluid in the inlet chamber is drawn into the compression chamber, so that fluid flows from the fluid chamber into the inlet chamber.
