Valve device

The current invention relates to a valve device (1), in particular for tank ventilation in motor vehicles, having a valve housing (6, 7, 8) with an inlet fitting (10) and an outlet fitting (11), having an armature (26) that is provided inside the valve housing (6, 7, 8) and can be moved by means of an electromagnet (22), having a closing body (40) that is connected to the armature (26) and closes a sealing seat (13) of the outlet fitting (11) when the electromagnet (22) is without power and opens it when the electromagnet (22) is supplied with power wherein the free cross sectional area between the inlet fitting (10) and the outlet fitting (11) can be continuously changed, and having a spring element (50) which presses the closing body (40) with a slight pressure against the sealing seat (13). In order to assure a reliable seal of the sealing seat (13) in a simple manner, according to a first embodiment according to the invention, the spring element (50) is comprised of a leaf spring (48) which is connected on the one end to the armature (26) and on the other end to the closing body (40) and furthermore, is pre-stressed against the closing body (40). As an alternative embodiment possibility, a spring element (50) with a spiral spring (49) is proposed, which deforms exclusively in the direction of its longitudinal axis even during the stroke motion of the valve device (1).

Magnetic trigger mechanism

ActiveCN102549683AAttenuation of magnetic holding forceArmature AccelerationProtective switch operating/release mechanismsElectromagnets with armaturesSpring forceMagnetic flux
The invention relates to a magnetic trigger mechanism at least comprising a yoke having an armature opening, in which yoke an armature is placed, which armature is coaxially surrounded by at least one section of the coil body having at least one excitation coil and which is acted on by the force of a preloaded spring element and which remains in a first end position due to the magnetic retaining force of a permanent magnet when current is not flowing through the excitation coil, the permanent magnet being arranged in the area of the first end of the armature together with a base extending between the armature and the permanent magnet, and the second end position of the armature being achieved by means of a brief flow of current through the excitation coil together with the accompanying lowering of the magnetic retaining force and the spring force, which is effective then. The invention is characterized in that the first end of the armature, which first end faces away from the armature opening, is guided in the coil body in a centered manner, and the second of the armature, which second end faces the armature opening, is likewise guided in a centered manner by means of a centering ring centered in the coil body, the highly permeable centering ring lies against the yoke at the armature opening and can move radially relative to the yoke, the base is centered in the coil body, the centering ring together with the coil body ensuring that the armature lies flat in the area of the first end without tipping and always guaranteeing maximum retaining forces due to the armature lying flat, the spring element having a larger diameter than the armature, and the magnetic flux commutating upon triggering from a series connection to a parallel connection.

Assembly comprising at least two components that are fixed together

The invention relates to an assembly for a motor vehicle, comprising at least a first component (T, FA, FB) and a second component (FS, G), for example a carrier and a guide rail of a window lifter which are fixed together by means of at least one fastening element, in this case by a plurality of rivets (N1-N4). A fastening element (N1-N4) engages in two openings (72, 82, 92; 62; 62'), of which one opening respectively is formed in a receiving portion (7.1-7.4; 8.3, 8.3*, 8.4; 9.3, 9.4) of the first component (T; FA; FB) and one on a protrusion (6.1-6.4; 6.3', 6.4') of the second component (FS; G), wherein a protrusion (6.1-6.4; 6.3', 6.4') respectively protrudes in an associated receiving portion (7.1-7.4; 8.3, 8.3*, 8.4; 9.3, 9.4) and a flexible or elastic edge section (70, 80, 90) of a receiving portion (7.1, 7.3, 7.4; 8.3, 8.3*, 8.4, 9.3, 9.4) can be shifted in the direction of the associated protrusion (6.1-6.4; 6.3', 6.4'). The at least one edge section (70, 80, 90) that can be shifted in a flexible manner is designed and provided for compensating manufacturing tolerances, such that the two components (T, FS; FA, G; FB, G) automatically align to one another in the area of the flexible edge section (70, 80, 90) during the fastening process and can form a solid connection as intended, wherein the protruding section (6.1-6.4; 6.3', 6.4') is locked in the receiving portion by the edge section (70, 80, 90) which is shifted and pushed against the protruding section (6.1-6.4; 6.3', 6.4').
