a valve part having a tappet that can be moved by a drive, wherein the tappet opens or closes the outlet opening depending on its position; and a spring that is disposed between the valve block and the tappet. ## Claims ### Claim 1 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 a sealing section covering the at least one outlet opening upon movement of the tappet, the positioning pin surrounded by an annular groove provided in the bottom of the pot-like area. ### Claim 2 (depends on 1) The valve according to claim 1, wherein the pot-like area of the tappet is at an end of the tappet facing the valve block, and is guided on the valve block. ### Claim 3 (depends on 1) The valve according to claim 1, wherein the tappet is configured pin-like at its end facing the drive element. ### Claim 4 (depends on 1) The valve according to claim 1, wherein the tappet and the drive element are manufactured independently from each other and connected to each other rigidly. ### Claim 5 (depends on 1) The valve according to claim 1, wherein the drive element and the tappet comprise a single part. ### Claim 6 (depends on 1) The valve according to claim 1, wherein the pot-like area of the tappet is at an end of the tappet facing the valve block and the pot-like area has at least one ventilation opening, with the tappet featuring the sealing section at its pot-like area at an end opposite the drive element, and the at least one ventilation opening spaced from the sealing section. ### Claim 7 (depends on 6) The valve according to claim 6, wherein the at least one ventilation opening includes a longitudinal extension that is orientated at an angle from a drive direction. ### Claim 8 (depends on 1) The valve according to claim 1, wherein the tappet is configured in at least one part. ### Claim 9 (depends on 1) The valve according to claim 1, wherein at least a portion of the tappet is manufactured by at least one of a punching process and a pressing process. ### Claim 10 (depends on 1) The valve according to claim 1, further comprising at least one of a slideway and a hardening of interacting surfaces of the tappet. ### Claim 11 (depends on 1) The valve according to claim 1, wherein the drive element comprises an armature supported movably in an armature space, such that when a magnetic coil carrying windings of current-conducting wire is electrified, the armature is moved to reduce or close a gap of working air. ### Claim 12 (depends on 11) The valve according to claim 11, wherein the solenoid comprises a magnetic core having an opening for translation of the tappet within the magnetic core, wherein the armature space is limited by the magnetic core. ### Claim 13 (depends on 11) The valve according to claim 11, wherein the solenoid comprises a magnetic core, and the gap of working air is located annularly about the armature, between the magnetic core and the armature. ### Claim 14 (depends on 9) The valve according to claim 9, wherein at least a portion of the tappet is manufactured in a cold forming process. ### Claim 15 (depends on 10) The valve according to claim 10, wherein the slideway comprises at least one of a sliding coating and a film bearing of the tappet on the valve block. ### Claim 16 (depends on 12) The valve according to claim 12, wherein the magnetic core has a recessed opening for receiving the pin-like area of the tappet. ### Claim 17 (depends on 1) The valve according to claim 1, wherein the spring is contained within the pot-like area of the tappet. ### Claim 18 (depends on 1) The valve of claim 1, wherein the spring is provided outside of an armature space into which the drive element comprising an armature is operatively disposed. ### Claim 19 (depends on 1) The valve of claim 1, wherein an upper side of the cylindrical valve part comprises: a positioning pin for guiding the spring, and an annular groove surrounding the positioning pin for retaining the spring. ### Claim 20 A solenoid valve comprising: a drive part having a drive element that is drivable by a drive solenoid; and a valve part, at least a portion of which is contained within a housing, the valve part comprising: a cylindrical-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; a movable tappet having a pot-like area, the tappet in operative connection with the drive part to open or close the at least one outlet opening depending on a position or the tappet; and a spring disposed between the valve block and the tappet, such that the drive element angles the tappet against a return force of the spring, wherein the pot-like area of the tappet includes a sealing section that surrounds a cylindrical-shaped portion of the valve block and that covers and uncovers the at least one outlet opening upon movement of the tappet.
