Control device for gas valves already caught on throughout this country

摘要

"Control device for gas valves already caught on throughout this country.The present invention relates to a device for the control of valves already caught on throughout this country gas of an internal combustion engine.Having respectively valve actuators (11) coupled to a hydraulic valve respectively swing gas that respectively have a plunger for adjustment (13) acting on the valve t.Rocadora gas, and two working chambers (121, 122) bounded by hydraulic adjustment piston (13).Of which the first working chamber (121) which urges the valve swing gas (10) in the direction of the closure is permanently filled with a fluid under pressure.And the second working chamber (122) which urges the valve swing gas (10) in the direction of the opening can be filled and discharged selectively with a fluid under pressure through aA first and a second electric control valve (24, 25, 26, 27).Aiming at cost reduction, respectively two valve actuators (11) are activated alternately by first and second by the same control valve (24 or 26, 25 or 27),And the switching of switching valves (24, 25, 26, 27) is made during the state of closing the two valves already caught on throughout this country gas (10) operated by the actuator valve (11).
