  • 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.

  • Patent number: 9963135
    Abstract: The invention relates to a valve unit for modulating the pressure in a pneumatic brake system, comprising a brake pressure inlet, a brake pressure outlet, a vent outlet, a diaphragm inlet valve, a diaphragm outlet valve, and a pilot valve for each diaphragm valve, the pilot valves being arranged in an elongate valve housing (having a main housing and a housing cover. The inlet valve pilot valve and the outlet valve pilot valve are arranged substantially centrally above the diaphragms of the inlet valve and the outlet valve in the housing cover and with the actuation axes of the pilot valves running parallel to the parting plane, and the housing cover includes a central insert which has valve bores and control channels and into which the solenoids and the mechanical components of the pilot valves are inserted, the central insert being encapsulated with a plastic material.
