Abstract

PURPOSE:To simplify structure, and to shorten working hours and to facilitate maintenance and supervision by providing rubberlike elastic bodies in containers wherein the elastic bodies are used as buffer, return spring, and stopper means. CONSTITUTION:Containers 7 opened at back end sides are arranged on the back end sides of fixed cores 1 and rubberlike elastic bodies 8 consisting of rubber or an equivalent material are accommodated in the containers 7. The elastic bodies 8 are pressed from the back end sides at suction operation by pressing arms 9 installed at the back end section of a plunger shaft 6. A rubberlike elastic body 11 for returning is intervened and inserted between the arms 9 and a stopper 10 opposing to the back end sides of the arms 9 by fixing through the plunger 6, the back end sides of the arms 9, and the fixed cores 1. When coils 4 are not excited, an interval lg is provided between fixed and moving coils 1, 3 to form intervals ls between the side walls of the containers 7 and the elastic bodies 8. In this way, structure and operating time become simple and short respectively and maintenance and supervision will be facilitated.
