Abstract:
A high-pressure pump arrangement (1) which can be especially used for a common rail injection system and has a pump member (2) that contains a low-pressure inlet (8) and a high-pressure outlet (9). A pressurization chamber (12) is provided, within which a plunger (3) is movably mounted and which is connected to the high-pressure outlet via a high-pressure valve (7). Furthermore, a suction chamber (6) that is fitted with a suction valve (5) is provided within the pump member. In addition, an intake duct (13) which extends between the low-pressure inlet and the suction chamber is provided within the pump member. The low-pressure inlet is connected to an electrically regulated pre-supply pump (10) which is permanently operated such that a low pressure is sure to be maintained in the suction chamber (6) of the pump.
