Problems solved by technology

In this case, in particularly unfavorable operating states of the valve device, for example, the pressure spring can be displaced from its seat on the valve body, so that a force component acting on the valve tappet and in the opening direction of the valve seat leads to a Undesirable influence on valve function

Embodiment Construction

[0019] figure 1 A part of a solenoid-actuated valve arrangement is shown in a schematic longitudinal section. The valve device 1 has a valve element 5 which is arranged longitudinally movable in a valve housing 2 and cooperates with a valve seat 4 formed in a valve body 3 .

[0020] The area of ​​the valve element 5 facing the valve seat 4 is arranged in a valve chamber 7 defined by the valve housing 2 in the area of ​​the valve seat 4, the dimensions of which are determined by figure 1 The rectangle drawn by the dotted line in the middle shows in detail, wherein the area of ​​the valve element 5 assigned to the valve chamber 7 has a first cylindrical area 5A, a second cylindrical area 5B with a smaller diameter following the cylindrical area 5A, a subsequent A frustoconical region 5C of the second cylindrical region 5B, a third cylindrical region 5D following the frustoconical region 5C and a spherical arch region 5E following the third cylindrical region 5D. The spherical ...

Abstract

The present invention relates to a valve device(1), which has a valve unit (5) longitudinally movable in a valve insert (2) and cooperating with a valve seat (4) formed in a valve body (3). An electromagnetic actuator stresses the unit (5) in closing direction of the seat(4). At least a part of the unit (5)is in a valve chamber (7) delimited by the insert (2) at the seat(4). According to the invention, the valve has a retention device (15) that cooperates with a valve unit (5) and holds the unit in a position equivalent to an open position of a valve seat (4) before control of the unit by an actuator. The actuator acts in closing direction of the seat and the operation of the retention device is neutralized after the control of the unit by the actuator.

Description

technical field [0001] The invention relates to a valve device having a valve element disposed longitudinally displaceably in a valve housing and cooperating with a valve seat formed in a valve body, the valve element passing through the An electromagnetic driver is operable in the closing direction of the valve seat, wherein at least a part of the valve element is arranged in a valve chamber defined by the valve box in the area of ​​the valve seat, a retaining mechanism cooperating with the valve element is provided so that the valve The element is held by the retaining mechanism in a position corresponding to an open state of the valve seat prior to a first operation on the part of the driver. Background technique [0002] DE 100 36 576 A1 discloses a valve arrangement, or rather a solenoid-actuated valve, which can also be used in a hydraulic brake system of a motor vehicle. The valve arrangement is realized with a valve housing, which has an elongated hole. In addition...
