  • Patent number: 9636963
    Abstract: An end member assembly (204; 404) that is dimensioned for use in forming a gas spring assembly (200; 400) can include an end member body (248; 448) that is dimensioned for securement to a flexible spring member (206; 406) of the gas spring assembly (200; 400). The end member assembly (204; 404) can also include a compliant support structure (250; 450) that is operatively connected to the end member body (248; 448) to support the end member body in spaced relation to an associated structural component (SC2). The end member body (248; 448) can include a side wall (256; 456) that extends in overlapping (OL1; OL2) relation with at least a portion of the compliant support structure (250; 450). The end member (204; 404) can also form at least one chamber (296; 508) within the end member body (248; 448) and compliant support structure (250; 450). A gas spring assembly (200; 400) and a suspension system (118) are also included.

  • Patent number: 6556116
    Abstract: A method for inhibiting or eliminating case erosion in a pencil ignition coil having an internal primary winding and an external secondary winding and shield. Three alternative means for resisting damage due to the partial discharge phenomenon arising from a high electric field in such coil configurations are provided: (i) applying an ozone resistant coating on the case; (ii) applying a coating on the case for eliminating partial discharge under the shield; and (iii) applying a polyimide tape covering to the case for resisting partial discharge under the shield.

  • Patent number: 6463919
    Abstract: An ignition coil assembly includes a cylindrical central core having a main axis, a primary winding outwardly of the central core, a secondary winding outwardly of the primary winding, and a case comprising polyimide material. In one embodiment, a secondary winding spool comprises polyimide material. The overall diameter of the ignition coil assembly is reduced relative to conventional designs.
