Embodiment Construction
[0040] figure 1 and 2 A first embodiment of a valve 1 for controlling fluids according to the invention is shown in a sectional side view. The valve 1 comprises a housing 2 and an actuating unit 7 . The actuating unit 7 comprises a coil housing 3 connected to the housing 2 by means of a flange 19 , a coil 13 arranged in the coil housing 3 , a coil body 17 , an iron core 16 , a sliding sleeve 20 and an armature 14 . The coil 13 is surrounded by a coil body 17 and can be connected to a power source by a cable not shown. The coil 13 surrounds the iron core 16 which is connected to the coil case 3 . The armature 14 is disc-shaped and has a circular projection 6 , wherein, at its jacket inner surface 24 , a cone is formed at the circular projection 6 .
[0041] The iron core 16 has a cone 27 at the end facing the armature 14 .
[0042] O-rings 15 are arranged between the housing 2 , the flange 19 and the iron core 16 , these O-rings statically seal the coil 13 from the cavity ...

Abstract
A valve (1, 28, 36, 51) comprising: a housing (2, 38, 52) having an inlet (11, 40) and an outlet (12, 29, 41); a closure (9, 30, 47 , 53), which are displaceable between a first position and a second position, wherein in the first position, a flow path (26, 34, 35, 50, 57), and wherein in the second position, the flow path (26, 34, 35, 50, 57) is interrupted or formed; and the actuation unit (7) has a coil (13) and an armature ( 14, 37). Subject to the current applied to the coil (13), the armature (14, 37) displaces the closure (9, 30, 47, 53) between two positions, wherein the armature (14, 37) has a cone, Wherein the force on the armature (14, 37) can be changed by the inclination of the cone.
Description
technical field [0001] The present invention relates to a valve for controlling a fluid, the valve comprising: a housing having a cavity with at least one flow opening, at least one inlet and at least one outlet connected to the cavity; at least one closure, which Displaceable between a first position and a second position, wherein in the first position a flow path is formed from the at least one inlet through the cavity to the at least one outlet via the at least one flow opening, wherein in the second position, At least one closure closes the at least one flow opening such that the flow path is interrupted; and an actuation unit having a coil, a coil housing, a core at least partially surrounded by the coil, and an armature coupled to the at least one closure and in the A cavity is disposed on the surface of the iron core, wherein fluid flowing through the cavity flows around the armature, and wherein is subjected to current applied to the coil, the armature holds the at lea...
