Title: PRESSURE-DAMPENING DEVICE FOR A FLUID PUMP, IN PARTICULAR FOR A HIGH-PRESSURE PUMP OF A FUEL INJECTION SYSTEM
Abstract:
The invention relates to a pressure damping device (20) for a fluid pump (10), in particular for a high-pressure pump of a fuel injection system, said device comprising at least one damping element (30) which is arranged in the fluid chamber (15). The fluid chamber (15) is associated with a housing (11) of the fluid pump (10) and comprises a housing cover (21). The housing (11) of the fluid pump (10) comprises a cavity (14) which essentially forms the fluid chamber (15) and in which the at least one damping element (30) is essentially lowered.
