Device for operating an internal combustion engine gas exchange valve with an electromagnetic actuator incorporates an electromagnetic unit with electromagnetic opening and closing magnets surrounding a sliding rotor

摘要

An electromagnetic unit (3) has electromagnetic opening (13) and closing (14) magnets, between which a rotor (6) slides coaxially. Guided by a rotor shank guide (15) in the opening magnet, the rotor uses a rotor shank (16) and a hydraulic play-balancing element (5) to affect a valve shank (17) guided by a shank guide (18) in a cylinder head (19). The hydraulic play-balancing element connects to an oil-hydraulic connection via the rotor shank and a long channel in it.
