Embodiment Construction

[0025] FIG. 1 shows an electromagnetically actuated valve arrangement 1 with a valve element 5 arranged so as to be movable longitudinally in the valve housing 2 and cooperating with a valve seat 4 formed on the valve body 3 . The valve element 5 is loaded in the installed position by a force component acting in the opening direction of the valve seat 4, and is driven in the closing direction of the valve seat 4 by the electromagnetic excitation device or the electrical assembly 1B.

[0026] The spring device 6 is arranged between the valve body 5 and the valve body 3, wherein the spring device 6 formed by the coil spring 6A is installed between the valve body 3 and the valve body 5 without pretension when the electrical component 1B is not energized, The valve member 5 is in a position corresponding to the state in which the valve seat 4 is opened as shown in FIG. 1 .

[0027] The part of the valve member 5 facing the valve seat 4 is arranged in the valve chamber 7 defined by...

Abstract

The present invention provides a solenoid actuating valve device (1), comprising a spring mean (6) acting in the opening direction. The limit of tolerance of the length of the spring mean (6) and the axial length of the spring mean (6) mounting chamber are compatible, the valve (5) is raised at least minimum stroke to the evacuated needed valve base (4) by the spring mean under the condition of the power-off of the actuator (1B), the spring mean (6) locates in unbounded prestressed state when the valve base (4) is completely opened.

Description

technical field [0001] The invention relates to a valve device as defined in the preamble of claim 1, having a valve member arranged longitudinally movable in a valve housing and cooperating with a valve seat formed on the valve body. Background technique [0002] Known valve arrangements of this type consisting of solenoid-actuated valves have hydraulic components and solenoid components or solenoid actuators for controlling the valve arrangement, in particular for pressure brake regulation such as ABS systems (anti-lock brake systems). system, TCS system (traction-control-system) or ESP system (electronic stability program). [0003] A valve device of this type comprises a valve housing with a longitudinal bore, a valve housing connected to the valve housing, an armature arranged so as to be movable longitudinally in the valve housing, and a valve stem or valve element. The valve element and the armature are connected to each other so that a movement of the armature in th...
