Abstract

PURPOSE: To set the characteristic of attraction force acted on the armature of the electromagnetic solenoid by an arrangement wherein the position of the armature is detected by a magnetoelectric converter and a control circuit to be controlled based on output signals from the converter is provided in a current supplying circuit for the coil of the electromagnetic solenoid.
CONSTITUTION: An electromagnetic solenoid 10 consists of an armature 1, a magnetic path 3 and a coil 4, and a magnetic gap S is provided at one portion of the magnetic path 3. A magnetic path changing member X made of ferromagnetic materials is provided in relation to the armature 1 to be inserted into or removed from the gap S with the movement of the armature 1. A magnetoelectric converter 7 is provided near the gap S. A control circuit 9, which controls the level of drive current to be passed through the coil 4 of the electromagnetic solenoid 10 to keep the relation between the position of the armature 1 and the attraction fore acted on the armature 1 at the predetermine condition in response to control signals produced based on the quantity of electricity corresponding to the leaked quantity of magnetic flux through the gap S detected by the converter 7, is provided in a current supplying circuit for the solenoid 10.
