Abstract
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.
