  • Publication number: 20110215270
    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.

  • Publication number: 20100264342
    Abstract: 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.

  • Patent number: 7575218
    Abstract: The invention relates to a magnet valve, having a valve insert and a tappet guided movably in the valve insert via a tappet guide, which tappet is braced on a valve body via a restoring spring resting a contact face of the tappet, and the restoring spring is guided radially from inside on one end by a spring guide of the tappet, the spring guide adjoining the contact face. According to the invention, centering means are present, which are disposed on the tappet in such a way that the restoring spring is centered and radially guided from inside over a substantial portion of its length.

  • Publication number: 20060081803
    Abstract: An electromagnetically actuatable valve for braking force systems in motor vehicles, has a valve housing, with tappet element axially displaceable in the housing cooperating with a valve body and forming a sealing seat at a sealing face. The valve housing has a plurality of radially extending pressure medium outlet bores which are covered by a filter element. The disposition and embodiment of the outlet bores results in a flow course for the pressure medium that reduces the flow resistance of the valve and thus improves the valve properties.
