Electromagnetic valve unit for I.C. engine

摘要

The drive includes two electromagnets, whose pole surface areas face each other at least partially, and a movable armature arranged reciprocating between these pole surface areas. The armature is held in an intermediate position using spring while the electromagnets are turned off. The armature is brought, at switching on of one of the magnets, into one of two end positions, at least nearby the pole surface areas of the corresponding electro-magnet. The armature is connected with the part to be driven. Two such drives (2, 3, 10) are combined to a building unit, whereby both drives are preferably assembled on a common main body (1).
