  • Patent number: 8205857
    Abstract: A pressure regulating valve (10) includes a magnet coil (16) received in a coil body (18), an armature (26) movable relative to a pole piece (20) for actuating a valve closing member (36), and a magnetic circuit (48) containing a magnet yoke (50). The magnetic circuit (48) has a maximum of three components (20, 66; 26, 50) that together form magnetic transitions (72, 74) oriented in the axial direction.

  • Publication number: 20100090142
    Abstract: The invention relates to a pressure control valve (10) having a magnet coil (16) which is accommodated in a coil body (18). The pressure control valve (10) comprises an armature (26) which can move relative to a pole piece (20) for actuating a valve closing element (36). A magnetic circuit (48) is formed in the pressure control valve (10), which magnetic circuit (48) comprises at most three components (20, 26, 50) which together form magnetic transitions (72, 74) which are oriented in the axial direction.

  • Publication number: 20100084589
    Abstract: A slide valve is used for controlling the hydraulic system in a motor vehicle automatic transmission. It includes a housing, a valve slide that is guided in the housing, which has a plurality of adjacent sections having different diameters. Furthermore, an electromagnetic operating device is provided, which is able to impinge upon the valve slide at least in a first effective direction. An impingement device impinges upon the valve slide counter to the first effective direction.
