ELECTROMAGNETIC VALVE ACTUATOR FOR STOP-FREE ELECTROMAGNETICALLY ACTUATED VALVE, VALVE AND RECIPROCATING PISTON INTERNAL COMBUSTION ENGINE WITH VALVE

摘要

An electromagnetic valve actuator (4) is specified for an electrically actuated valve (E-OCV=electronically operated control valve or electronic open close valve) that has a solenoid coil (10) fixed to a housing, two permanent magnets (12, 16) fixed to the housing and a third permanent magnet (18) that can be moved together with a valve body and for which, when no voltage is present at the solenoid coil (10), a repelling position of equilibrium between the permanent magnets is set in which the third permanent magnet is held in a magnetically repelling manner between the permanent magnets fixed to the housing. As a result of the electromagnetic valve actuator, the electromagnetically actuated valve is fast-switching and can be freely set and operates preferably in a stop-free manner. A reciprocating piston internal combustion engine having such a valve is also specified.
