Problems solved by technology

[0008] However, there is also the disadvantage here that when the valve device is in operation, there can be axial and radial relative movements between the armature and the valve element, so that the position of the valve element with respect to the position of the armature cannot be precisely determined for the entire operating range of the valve device , and when the valve device is in operation, the valve element generates vibrations and other highly dynamic movements due to its small mass, which negatively affects the operating and adjustment characteristics of the valve device

Embodiment Construction

[0016] The figure shows a part of the electromagnetically operable valve device 1 in a simplified longitudinal section. The valve device 1 has a valve element 5 that can move longitudinally in the valve bushing 2 and cooperates with a valve seat 4 formed in the valve body 3.

[0017] The area of ​​the valve element 5 facing the valve seat 4 is located in the valve cavity 7 defined by the valve bushing 2 in the area of ​​the valve seat 4, wherein the outline size of the valve cavity is further shown by the rectangle drawn with a dashed line in FIG. 1. The area of ​​the valve element 5 facing the valve cavity 7 has a first cylindrical area 5A, a second cylindrical area 5B resting on the cylindrical area 5A and having a reduced diameter, and a conical area 5C connected to the second cylindrical area 5B , The third cylindrical area 5C connected to the conical area 5C and the dome-shaped area 5E connected to the third cylindrical area 5D.

[0018] The dome-shaped area 5E of the valve e...

Abstract

The valve device (1) has a valve element (5) which is movable longitudinally in the valve bushing (2) and cooperates with a valve seat (4) formed in the valve body (3). It can be operated in the closing direction of the valve seat (4) by an electromagnetic actuator. At least a part of the valve element (5) is arranged in a valve chamber (7) delimited by the valve bushing (2) in the region of the valve seat (4). Furthermore, the end of the valve element (5) facing away from the valve chamber (7) is operatively connected to the armature (10). The valve element (5) is effectively connected with the armature (10) through the connection device (16), so that in the abutment area between the armature (10) and the valve element (5), the armature (10) and the valve element ( 5) There is basically no relative movement in the axial and radial directions of the valve element (5).

Description

Technical field [0001] The invention relates to a valve device of the type further defined in the preamble of claim 1. Background technique [0002] From DE 100 36 576 A1, a solenoid valve or an electromagnetically controllable valve device is known, which can be used in a hydraulic brake device of a motor vehicle. The valve device has a valve bush with a longitudinal hole, which is connected to the valve cover. An armature that can move longitudinally in the axial direction of the valve device is arranged in the valve cover, and the armature is effectively connected to a valve push rod that can also move longitudinally in the axial direction in the valve bushing. [0003] The armature and the valve push rod or valve element are connected here so that the movement of the armature in the closing direction of the valve seat is transmitted to the valve push rod with the closing member, and the seat valve is abutted on the valve seat at the closing member Case closed. [0004] The va...
