Abstract
The invention relates to a magnet valve, in particular for a slip-controlled hydraulic vehicle brake system, having a valve carrier bush and a guide sleeve, extending through an opening of the valve carrier bush and joined thereto by positive engagement by means of a caulked feature, in which sleeve an armature and a valve closing body are received displaceably relative to a magnet core and a valve seat, and having an electrical coil surrounding the guide sleeve in the region of the magnet core. The invention proposes that a flange, embodied as a radially outward-pointing crease is formed onto the guide sleeve and is braced in fluid- and pressure-tight fashion by the caulked feature against a radially inner, steplike shoulder of the valve carrier bush, and the flange has flat end portions, extending transversely to a magnet valve axis, which rest on one another substantially without any space between them.
