摘要： A device 1 for controlling a gas exchange valve 2 for an internal combustion engine comprises: an electro-hydraulic valve actuator 36, means 13, 14 for influencing the valve actuator 36 in the opening direction of the gas exchange valve 2 by means of a fluid which is subjected to actuation pressure, and means 20 for the controlled discharge of the fluid out of the valve actuator 36. In order to be able to reliably and precisely adjust the closing speed of the gas exchange valve 2 and thus the speed at which a valve disc 5 of the gas exchange valve 2 impinges upon the valve seat ring 6, there is included a means 20 for the controlled discharge of the fluid comprising a pressure-controlled restrictor clement 22 which can be influenced by a control pressure and the device 1 further comprises means 24, 25, 26 to regulate the control pressure to a predeterminable pressure value.

摘要： A device for controlling gas-exchange valves of an internal combustion engine is provided, which device has hydraulic valve actuators each allocated to one gas-exchange valve. Each valve actuator has an actuating piston acting on the gas-exchange valve, and two hydraulic working chambers delimited by the actuating piston, of which the first working chamber acting upon the gas-exchange valve in the closing direction is constantly filled with fluid under pressure, and the second working chamber acting upon the gas-exchange valve in the opening direction is able to be alternately filled with fluid under pressure and relieved via two electric control valves. For the purpose of cost reduction, provided for each valve-actuator pair is a single first electric control valve that is acted upon with the fluid pressure on the intake side, and is connected on the outlet side to the second working chamber of one valve actuator. The second working chamber of the other valve actuator is filled with fluid with the aid of a switchover valve and the fluid pressure in the second working chamber of the one valve actuator.

摘要： The invention relates to a connection (24) between a stem end (20) on a gas exchange valve (1) in an internal combustion engine and a sleeve-like actuator body (2) of a valve actuator (4), which may be axially displaced within a pressure region (58) pressurised with a pressure agent in the valve actuator (4) and which at least partially encloses the stem end (20). According to the invention, the connection is formed outside the pressure region (58) and arranged in the region of an opening (16) which is preferably coaxial with the stem end (20) and formed on the side of the valve actuator (4) away from the combustion chamber.

摘要： Die Erfindung betrifft Einspritzsysteme für Verbrennungsmaschinen mit einem gemeinsamen Hochdruckspeicher für mehrere Zylinder. Das Einspritzsystem (200) umfasst weiterhin eine Hochdruckpumpe (202); ein Druckregelventil (208); und ein Steuergerät (214) zur Ansteuerung des Druckregelventils (208), um im Normalbetrieb einen Systemdruck im Speicher (204) aufrecht zu erhalten. Das Druckregelventil (208) gibt ohne Ansteuerung den Ablauf in eine Niederdruckleitung (210) mindestens teilweise frei. Mit einer Drosselkomponente (218) ist ein Kraftstofffluss aus dem Hochdruckspeicher (204) in die Niederdruckleitung (210) so beschränkbar, dass wenigstens ein für den Betrieb der Verbrennungsmaschine erforderlicher Mindestdruck im Hochdruckspeicher (204) gewährleistet ist. Die Drosselkomponente (218) ist unabhängig von der Ansteuerung (220) des Druckregelventils (208) betätigbar.

摘要： Disclosed is a simple, easy-to-produce, and reliable connection between a shaft of a gas exchange valve and an actuator. This connection is detachable and, as a result, can be connected and disconnected multiple times. It is also possible to dispose the coupling piece on the shaft of the gas exchange valve and provide circumferential grooves on the control element of the actuator.

摘要： A pressure-supply device for an electrohydraulic valve control of gas-exchange valves in internal combustion engines which has a fluid reservoir, a fluid output for the connection of the valve control, and a high-pressure pump which removes fluid from the fluid reservoir and delivers it under high pressure to the fluid output. To attain high pump efficiency and high system dynamics, the high-pressure pump is constructed as constant-displacement pump having a pump inlet and a pump outlet, and the pump outlet is connectible by a switchover valve alternately to the fluid output and, accompanied by blocking of the fluid output, to the fluid reservoir.

摘要： The invention relates to a device for controlling gas exchange valves in an internal combustion engine, said device having hydraulic valve actuators (17, 18) comprising actuating plungers (26) acting upon a gas exchange valve (12, 13) and working chambers (27, 28) defined by the actuating plunger (26). The first working chamber (27) for closing the gas exchange valve (12, 13) is permanently under fluid pressure and the second working chamber (28) for opening the gas exchange valve (10) is alternately filled with and emptied of a pressurized fluid by means of a first and a second electrical control valve (34, 35). In order to reduce the number of required control valves, the second working chamber (28) of the second valve actuator (18) in a pair of valves is filled through the second working chamber (28) of the first valve actuator (17) that is connected to the first control valve (34) once a given stroke of the actuating plunger (26) of the first valve actuator (17) is carried out so as to open the assigned gas exchange valve (12).
