Abstract:
1. A solenoid valve comprising a valve housing with a valve passage; a valve closing member arranged in the valve housing and configured to open or close the valve passage; an electromagnet armature for actuating the valve closing member, the electromagnet armature being configured for relative movement in a range of a defined working stroke; a return spring acting on the electromagnet armature and having a spring end remote from the electromagnet armature and supported on a magnetic core in the valve housing, the valve housing comprising a thick-walled tubular body for fixing in a valve seating bore, the tubular body being connected to a thin-walled sleeve having a radially circumferential flange, the circumferential flange being in contact with an internal step in the tubular body, the tubular body having an axial annular groove with a groove bottom, the groove having a width continuously diminishing toward the groove bottom and a radially inner groove wall forming an acute angle with a cylindrical axis of the tubular body, the annular groove separating an axial radially outer end face from an axial radially inner end face at a radial distance from the internal step, at least the radially inner end face extending in a radial plane, the radial distance being dimensioned to leave a stay collar forming the radially inner end face between the internal step and the axial annular groove on the tubular body, the stay collar connecting the tubular body to the sleeve, wherein the radially inner end face is axially offset from the from the radially outer end face, and wherein the stay collar is axially positioned between the circumferential flange of the sleeve and the valve closing member.
