Abstract

A hydraulic part of a magnet valve is received in a bore of a valve block. The hydraulic part is secured to the valve block with a calked heel of a securing bush that is slipped onto a guide sleeve of the hydraulic part. The securing bush rests on an annular shoulder of the guide sleeve and engages a jacket wall of the guide sleeve with a press fit, and one edge of the securing bush is adapted to a rounded-out throat between the jacket wall and an end wall of the annular shoulder by means of plastic deformation. A valve sleeve engages a portion of the bore of the valve block with a press fit. The calked heel, the plastically deformed edge of the securing bush, and the press fit of the valve bush seals that seal off against fluid are achieved without using additional rubber-elastic sealing means.
