A solenoid valve comprising:
- a drive solenoid including a drive element;
- and
- a valve part, at least a portion of which is contained within a housing, the valve part comprising:
- a valve block contained within the housing and comprising a substantially cylindrical portion having at least one outlet opening,
- a widening portion of increased volume and outside of the housing, and
- a connecting ring formed between the cylindrical portion of the valve block and the widening portion and in contact with an end of an inside of the housing;
- and
- a movable tappet in operative connection with the drive element of the drive solenoid, the tappet structured and arranged to open and close the at least one outlet opening depending on a position of the tappet, and
- a spring arranged between the valve block and the tappet,
- the drive element angling the tappet against a return force of the spring,
- the tappet including a pot-like area having:
- a bottom,
- a positioning pin for guiding the spring, and
- a terminal face disposed about at least a portion of the valve block and having at least one of a slide surface and a guide surface for sliding the tappet on the valve block and
