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： A high pressure container arrangement includes a reservoir having an outer wall and an over pressure relief orifice through which high pressure fluid may flow when the fluid pressure inside the reservoir exceeds a predetermined pressure threshold. The high pressure container arrangement also includes a pressure limiting valve having a housing in which is arranged a closing member permanently biased by a spring toward a closed position and, when the pressure in the reservoir exceeds the predetermined threshold the closing member is pushed in an open position. The housing of the pressure limiting valve is integral to the wall of the reservoir.
