20100264342 | VALVE CARTRIDGE FOR A SOLENOID VALVE, AND ASSOCIATED SOLENOID VALVE - The invention relates to a valve cartridge for a solenoid valve, having a capsule, a magnetic armature that is movably guided within the capsule, a valve insert that is inserted into the capsule at a first end, and a valve body, which is pressed into a second end of the valve insert and has a main valve seat. The magnetic armature, moved by a generated magnetic force, moves a tappet guided within the valve insert. The tappet has a closing element with a sealing element which plunges into the main valve seat of the valve body in a sealing manner for carrying out a sealing function, and an associated solenoid valve. According to the invention the valve insert is configured as a one-part slotted bushing, and the valve body is configured as a bonnet-shaped bushing. The valve body configured as a bushing is pressed into a second end of the valve insert configured as a slotted bushing such that the main valve seat is disposed within the valve insert. | 10-21-2010 |
20110198522 | SOLENOID VALVE - 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. | 08-18-2011 |
20110215270 | Solenoid Valve for Controlling a Fluid - 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. | 09-08-2011 |
20120161047 | Solenoid Valve - 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. | 06-28-2012 |
