Abstract
Es wird eine Vorrichtung zur Beeinflussung, insbesondere Verringerung von Druckpulsationen in einem hydraulischen System, vorgeschlagen, die ein vom im hydraulischen System herrschenden Druck beaufschlagtes Element (56) aufweist, das abhängig vom im hydraulischen System herrschenden Druck bewegbar ist. Die Vorrichtung weist eine Sensoreinrichtung (52) auf, durch die der im hydraulischen System herrschende Druck erfasst wird. Die Sensoreinrichtung (52) ist mit einer elektronischen Steuereinrichtung (54) verbunden, durch die Änderungen des im hydraulischen System herrschenden Drucks ausgewertet werden. Zur Bewegung des druckbeaufschlagten Elements (56) ist ein Aktor (60) vorgesehen, der durch die Steuereinrichtung (54) derart angesteuert wird, dass durch das druckbeaufschlagte Element (56) den ermittelten Druckänderungen im hydraulischen System sich überlagernde, insbesondere entgegenwirkende Druckänderungen im hydraulischen System bewirkt werden. Das hydraulische System ist vorzugsweise ein Niederdruckbereich einer Kraftstoffhochdruckpumpe. A device for influencing, in particular reducing, pressure pulsations in a hydraulic system is proposed which has an element (56) which is acted upon by the pressure prevailing in the hydraulic system and which can be moved as a function of the pressure prevailing in the hydraulic system. The device has a sensor device (52) by means of which the pressure prevailing in the hydraulic system is detected. The sensor device (52) is connected to an electronic control device (54), by means of which changes in the pressure prevailing in the hydraulic system are evaluated. An actuator (60) is provided for moving the pressurized element (56), which is controlled by the control device (54) in such a way that the pressurized element (56) overlaps, in particular counteracts, pressure changes in the hydraulic system that overlap the determined pressure changes in the hydraulic system be effected. The hydraulic system is preferably a low pressure area of a high pressure fuel pump.
