Abstract

A conveniently assembled positive connection of a magnetically operated valve with a housing block which will withstand high stresses. The housing block has a stepped locating bore which, as the bore depth increases, leads into an undercut. A valve body section has a smaller diameter than the bore in the housing and has a shape which is adapted to the locating bore which leaves a gap between the bore and the valve body section. A sleeve is pressed into the gap which fills the gap, and which engages in the region of the undercut. The sleeve which is subjected to a deforming action, fixes the magnetically operated valve and can withstand high stresses.
