摘要： A high-pressure piston pump with a plurality of pump elements is connected on the intake side to a pump that pumps fuel at low pressure in a regulated quantity. Each pump element is preceded on the intake side by a first and a second check valve in series. The first check valve opens counter to spring force in the intake phase of the pump element and closes in the pumping phase. The second check valve opens counter to spring force and closes, reinforced by spring force, at pressures of the fuel supplied by the pump that are higher than the negative pressure generated in a cylinder chamber of the pump element. The second check valve takes on the metering of the fuel supplied to the pump element; the first check valve blocks off the cylinder chamber counter to the check valve in the pumping phase, whereby the piston pump serves to supply fuel at high pressure in fuel injection systems of internal combustion engines, especially in a common rail injection system.

摘要： A check valve assembly comprising a housing having a fluid inlet (112) arranged to be fluidly connected, in use, to a source of hydraulic fluid, a first stage body (122) having a first stage fluid outlet (128) and a second stage body (124) having a second stage fluid outlet (228) and a flow passage (126) between the first stage body and the second stage body, wherein the first stage body is a hollow body having a first end in fluid communication with the fluid inlet (112) and housing a hollow first stage retainer (140) around which is mounted a first stage spring (142) that biases a first stage ball (150), and wherein the second stage body is a hollow body housing a second stage retainer (130) around which is mounted a second stage spring (132) that biases a second stage ball (160), and wherein a first stage pressure differential between the first stage fluid outlet and the fluid inlet creates a fluid flow path from the inlet to the first stage fluid outlet and causes the first stage ball to press against the bias of the first stage spring to close the flow passage between the first stage body and the second stage body, and wherein removal of the first stage pressure differential causes the first stage spring to return the first stage ball to its biased position to close the flow path from the fluid inlet to the first stage fluid outlet and to open the fluid passage between the first stage body and the second stage body and a second stage differential pressure between the fluid passage and the second stage outlet presses the second stage ball against the bias of the second stage spring to open a second stage fluid flow path between the fluid passage and the second stage fluid outlet.
