Abstract

A magnet valve has a core sleeve in which a valve element is longitudinally movably arranged and has at least one housing sleeve overlaying the core sleeve which is connected to the core sleeve by welding from the outside. The weld is designed via a circumferential section or a plurality of circumferential sections of the housing sleeve forming at least one weld-free zone. A method for welding such a core sleeve of a magnet valve to the housing sleeve is also disclosed. The weld is made via a circumferential section or a plurality of circumferential sections of the housing sleeve, leaving at least one weld-free zone.
