    摘要： An apparatus for controlling gas exchange valves of an internal combustion engine having hydraulic valve actuators each assigned to one gas exchange valve, with one adjusting piston acting on the gas exchange valve and two hydraulic work chambers defined by the adjusting piston the first work chamber acting on the gas exchange valve in the closing direction being constantly filled with fluid that is under pressure, and the second work chamber acting on the gas exchange valve in the opening direction can be filled with and relieved of fluid that is under pressure in alternation via a first and second electrical control valve. Two valve actuators are each triggered in alternation by the same first and the same second control valve, and the switchover of the control valves is performed during the closing state of the two gas exchange valves actuated by these valve actuators.

    摘要： A hydraulically controlled actuator for actuation of an exhaust-side gas exchange valve of an internal combustion engine, containing a control piston that is displaceable within a cylinder and, with piston sides facing away from one another, delimits pressure chambers, of which the one pressure chamber impinges upon the gas exchange valve in the closing direction and the other pressure chamber impinges upon the gas exchange valve in the opening direction. In the actuator is provided at least one spring element, which can be brought into a preloaded state by the control piston moving in the closing direction of the gas exchange valve, and whose stored potential energy accelerates the gas exchange valve in the opening direction at least at the beginning of an opening phase, is provided. This results in a reduction in the energy expended in the context of valve actuation.

    摘要： In a method and a circuit system for operating a solenoid valve, particularly for actuating an electrohydraulic gas-exchange valve control, an injection valve, or an intake or exhaust valve of an internal combustion engine, to permit the simplest possible driving of the solenoid valve, the solenoid valve is acted upon in a controlled manner in a cycle including three phases, in which in a pull-up phase, the solenoid valve is connected for a predefined time duration to a first voltage of predetermined magnitude for generating a pull-up current, in a holding phase is connected to a second voltage of predetermined magnitude for generating a holding current, and in a de-energize phase is separated from both voltages.
