摘要：
A high pressure fuel pump unit includes a pump head where an inlet channel opens into a low-pressure chamber itself in fluid communication with a compression chamber. A valve is arranged so that when it is closed the fuel fills the low-pressure chamber and when the valve opens the fuel flows from the low-pressure chamber into the compression chamber. The pump head also includes a resilient member arranged so that when the valve is closed, the resilient member deforms to increase the volume of the low pressure chamber. When the valve opens, the fuel flows into the compression chamber, pushed by the resilient member which takes back its original shape.
摘要（中）：
高压燃料泵单元包括泵头，其中入口通道自身与压缩室流体连通地通向低压室。 阀被布置成使得当其被关闭时，燃料填充低压室，并且当阀打开时，燃料从低压室流入压缩室。 泵头还包括弹性构件，其布置成使得当阀关闭时，弹性构件变形以增加低压室的体积。 当阀打开时，燃料流入压缩室，由弹性构件推动，该弹性构件回收其原始形状。
