Abstract: The invention relates to a solenoid valve, particularly for controlling the brake pressure of a wheel brake of a slip-controllable hydraulic brake system of a motor vehicle. In known solenoid valves, there is a first hydraulically effective connection of an armature chamber of the solenoid valve to an outlet through the guide of a tappet in a valve insert. The first hydraulically effective connection ends in the form of a blind hole and thus does not permit flushing out gas bubbles which possibly have accumulated in the armature chamber. In order to solve this problem, the invention proposes a second hydraulically effective connection which is arranged away from the guide of the tappet, uncoupled from the first hydraulically effective connection. Thus, a closed pressure medium path is effected within a valve cartridge of the solenoid valve, the closed pressure medium path making possible an effective flushing of the armature chamber and thus a flushing out of gas bubbles.

Abstract: A solenoid valve includes a housing which extends in the axial direction and has at least one axial section which is embodied as a circular hollow cylinder, and a solenoid armature which is removably guided in the housing along a cylinder inner wall in an axial direction along the longitudinal axis of said housing and the solenoid armature having a solenoid armature casing wall. At least one axial flow duct for a medium is located in the housing and is provided to permit a flow around the solenoid armature. The flow duct has a first and a second duct wall region, and the first duct wall region is formed by a section of the cylinder inner wall and the second duct wall region is formed by a section of the solenoid armature casing wall. The second duct wall region is embodied as a planar second duct wall region.

Abstract: A solenoid valve for controlling fluids includes a pole core, an armature which is connected to a closing element, and a spring element which is arranged in a working gap between the pole core and the armature. The spring element includes a shaped spring of substantially disk-shaped design. The shaped spring has a curvature with at least one flank region and one dome region, a tangent to the dome region being parallel to an end surface of the pole core.

Abstract: A solenoid valve for controlling a fluid includes an armature having a base region, a lateral region and a head region. The solenoid valve includes a valve member connected to the armature. The solenoid valve further includes an armature casing component in which the armature is positioned. A flow path is formed between the armature and the armature casing component, the flow path extending from a lower armature space to an upper armature space and back to the lower armature space. A junction region is arranged between the head region and the lateral region. The junction region has at least one groove formed therein to facilitate an overflow between the lateral region and the head region.

Abstract: The invention relates to a solenoid valve with a magnet assembly and a valve cartridge having a pole core, a valve insert connected to the pole core, an armature which is guided within the valve insert in an axially movable manner between a closed position and an open position and is coupled to a closing element, and a valve body which is connected to the valve insert and has a main valve seat which is arranged between at least one first flow opening and a second flow opening. The axially movable armature, when the magnet assembly is energized, is moved by a generated magnetic force within the valve insert in the direction of the pole core counter to a spring force of a resetting spring and counter to a fluid force in order to lift the closing element out of the main valve seat; and to permit a flow of fluid between the at least one first flow opening and the second flow opening.

Abstract: An electromagnetically actuatable valve for brake systems in motor vehicles, comprises a hydraulic part and an electric part. The valve is partially placed inside a valve block, in which an inlet borehole and an outlet borehole for a hydraulic fluid are made. The hydraulic part comprises a valve element inside of which a transversal borehole is made that communicates with the inlet borehole. In addition, a number of longitudinal boreholes, which are connected to the outlet borehole, are made in the valve element. The transversal borehole and the longitudinal boreholes are connected via a closing element. The valve enables a controlled opening and closing of the closing element thereby making a low-noise switching of the valve possible.

Abstract: An electromagnetic valve arrangement with a valve element having least one part disposed in a valve chamber defined by a valve insert in the region of a valve seat. An end facing away from the valve chamber of the valve element is operatively connected to an armature and end face of the armature facing toward the valve insert and/or an end face of the valve insert facing toward the end face of the armature is embodied with a surface profile such that a flow cross section, defined by the opposed end faces varies at least regionally in the radial direction and/or in the circumferential direction of the armature.

Abstract: A valve arrangement having a valve element disposed longitudinally movably in a valve insert and cooperating with a valve seat in a valve body, which valve element in the installed position is acted upon, by a spring assembly disposed between the valve body and the valve insert, with a force component acting in the opening direction of the valve seat and is actuatable in the closing direction of the valve seat via an electromagnetic actuator. The spring assembly is guided in the radial direction in the region of a bearing face on the valve element. The spring assembly between its contact region on the valve element and its contact region on the valve body is guided in at least one further region in the radial direction on the valve insert.

Abstract: A valve (10) has a valve body (16) with a longitudinal bore (17), a valve dome (18) connected to the valve body (16), an armature (19) received longitudinally movably in the valve dome (18), and a tappet (36) for transmitting an armature motion to a closing member (40) of a seat valve (41). The tappet (36) is guided with slight radial play over the entire length of the longitudinal bore (17) of the valve body (16) and is provided on its jacket side with at least two separate conduits (37). A valve chamber (31) of the valve (10) that contains the seat valve (41) communicates fluidically with the valve dome (18) through the conduits (37). Residual air in the valve dome (18) can be positively displaced through the conduits (37).
