Embodiment Construction

[0019] figure 1A solenoid valve 1 is shown with a valve housing 2 which is closed on the upper side by a housing cap 3 and on the lower side by a sealing body 4 in a sealing manner. A valve lifter 5 is supported longitudinally displaceably in the interior of the valve housing 2 , the valve lifter is connected to an armature 6 axially in the direction of the housing cap 3 and a helical compression spring enclosing the valve lifter 5 7, wherein the helical compression spring 7 is supported on the one side on the armature 6 and on the other side on the valve body 9 axially adjacent to the valve tappet 5, said valve body There is a valve seat 8 for opening and closing by the valve lifter 5 . The valve housing 2 is substantially configured as a hollow cylinder for accommodating an armature 6, a valve tappet 5 connected to the armature, a valve body 9 with a valve seat 8 connected to the valve tappet and a valve body 9 connected to the valve tappet. The position of the tappet 5 i...

Abstract

The invention relates to a magnet valve, having a valve housing in which a valve body provided with a valve seat is at least partly disposed. A valve tappet is supported longitudinally displaceably in the valve housing and cooperates with the valve seat. A sealing body is provided so as to sealingly close off the valve housing on one of its ends. According to the invention the valve housing has an axial ring rib, which sealingly axially engages an annular groove of the sealing body.

Description

technical field [0001] The invention relates to a solenoid valve with a valve housing in which a valve body with a valve seat is at least partially arranged; A cooperating valve tappet and a sealing body sealingly close one end of the valve housing. Background technique [0002] Solenoid valves are known for isolating hydraulic circuits and for controlling and switching media in hydraulic circuits. The solenoid valve is designed as a de-energized open inlet valve with a valve housing (also known as a valve insert) in which a valve body with a sealing seat is controlled by a valve housing A movable valve tappet assigned to the armature and held open by a helical pressure spring through the application of force opens, or is closed by longitudinal movement of the armature and the valve tappet assigned to the armature when energized. The valve housing is closed and sealed at the ends by a closure cap which surrounds the pole core and which is itself surrounded by electromagnet...
