Abstract
A hydraulic system comprising a receiving body with electrohydraulic valve, with at least one hydraulic pump, and with channels for connecting the pump to at least one hydraulic load. A pulsation situation arises as a result of the delivery of a pressure medium by the pump and/or as a result of pressure medium being withdrawn by the load. At least one damping unit is provided, having a plurality of pulsation damping means such as, in particular, a damping chamber, and orifice. The hydraulic system provides a uniform and cost-effective solution for different operating situations and prevents a decrease in comfort. The damping unit has at least one switching means for adjusting the action of said damping unit to a varied pulsation situation by connecting or disconnecting one or more damping means.
