  • Publication number: 20200263637
    Abstract: An electromagnetic positioning device having anchor means which are realized for actuating a positioning partner and which are movable in an anchor space relative to stationary core means (30), which conduct magnetic flux, as a reaction to an energization of stationary coil means (32), the coil means, which have a coil support (32) provided with a winding and at least one external contactable connector (46), being embedded at least in sections in the core means and/or being surrounded by said core means and the core means realizing an end surface (34), which is planar at least in sections, for interacting with the anchor means, wherein the core means and the coil means are embedded in and/or surrounded by a one-piece pot-like and/or cup-like housing (38) made of a material suitable for deep-drawing in such a manner that the core means rest on a membrane-like, continuous and closed base section of the housing, the base section realizing a boundary surface of the anchor space.

  • Publication number: 20040178377
    Abstract: The invention relates to an electromagnetic regulating device (1) for a hydraulic control valve, comprising a housing (14, 15, 32) which comprises an electromagnet rotor arranged in a pressure pipe (2). Additionally, a distance measuring system (6) which detects the lift of the rotor is provided. Said pressure pipe (2) comprises a central thread (3) on one end thereof for securing onto the control valve and is made of a rotor conduit (7) and a sensor pipe which is connect thereto in a tight and secure manner. Said rotor conduit (7) lifts the rotor and supports a magnetic coil (5). Said sensor pipe (8) comprises a sensor coil (21) for detecting the way. Securing means are also provided for components which are semi-mounted on the pressure pipe (2). In the area at the end of the rotor conduit (7) orientated towards the sensor pipes (7), a collar (13) for holding the components arranged on the rotor conduit is provided and is firmly secured to said rotor conduit (7), rising above said conduit.
