Embodiment Construction

[0027] figure 1 and 2 A first embodiment of a valve 1 for controlling fluids according to the invention is shown in a side sectional view. The valve 1 comprises a housing 2 and an actuation unit 7 . The actuating unit 7 comprises a coil housing 3 connected to the housing 2 via 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 a core 16 which is connected to the core housing 3 . The armature 14 is disk-shaped and has a circular projection 6 , wherein a cone is formed on the circular projection 6 at its jacket inner surface 24 .

[0028] The core 16 has a cone 27 at the end facing the armature 14 .

[0029] Arranged between housing 2 , flange 19 and core 16 are O-rings 15 which statically seal coil 13 from cavity 10 formed in housing 2 . This offers the advantage tha...

Abstract

A valve (1, 28, 36, 51), comprising a housing (2, 38, 52) with an inlet (11, 40) and an outlet (12, 29, 41), a closure (9, 30, 47, 53), which is displaceable between a first position and a second position, wherein in the first position, a flow path (26, 34, 35, 50, 57) from the inlet (11, 40) to the outlet (12, 29, 41) is formed or interrupted, and wherein the flow path (26, 34, 35, 50, 57) is interrupted or formed in the second position, and an actuation unit (7) having a coil (13) and an armature (14, 37). The armature displaces the closure between the two positions subject to a current applied to the coil (13), wherein the armature (14, 37) has a cone, wherein a force on the armature (14, 37) is modifiable via an ascent of the cone.

Description

technical field [0001] The invention relates to a valve for controlling a fluid, which has the features of the preamble of claim 1 . Background technique [0002] Utility model DE 20 2010 004 556 U1 discloses a valve for controlling fluids, comprising a housing with a tubular cavity to which three connecting pieces are connected. Inside the tubular cavity there is a cylindrical closure with several grooves and displaceable between a first position and a second position. In the first position of the closure there is a flow path between two of the three connections and in the second position between the other two of the three connections, while in each case Both of them prevent fluid from flowing to the remaining third connector. Furthermore, the valve has an actuation unit comprising a stationary coil with a housing and a movable armature. The armature is flat, is coupled to the closure, and is arranged on the surface of the coil within the cavity, the armature being surro...
