Electromagnetic operating device for IC engine gas changing valve has carrier for actuator provided with ferromagnetic component acting as stop for opening magnet

摘要

The operating device has an actuator (2) with an opening magnet (9) and a closing magnet (10) cooperating with a sliding armature (19) acting on the valve shaft (4) of the gas changing valve (1), with closing and opening springs (22,23) holding the valve in a neutral position when neither magnet is energized. The carrier (3) for the actuator has an annular ferromagnetic component (33) positioned coaxial to the valve shaft and acts as a stop for the opening magnet.
