  • Method of producing a valve arrangement for an expansion valve
    Patent number: 7849600
    Abstract: The invention relates to a method of producing a valve arrangement and to a valve arrangement for an expansion valve, which is provided in a vehicle air conditioning system operated with refrigerant and has a basic opening in the valve seat, the cross section of this basic opening being produced for a predetermined mass flow by material removal.
    Type: Grant
    Filed: March 3, 2005
    Date of Patent: December 14, 2010
    Assignee: Otto Egelhof GmbH & Co. KG, Regelungstechnik
    Inventors: Uta Andrä, Siegfried Roth, Albrecht Waldenburg, Jean-Jacques Robin, Ralf Winterstein, Klaus Kummerow
  • Lamp socket
    Patent number: 7833059
    Abstract: A lamp socket has a housing forming a cavity centered on an axis and having a generally cylindrical side wall and a floor, an internally threaded sleeve coaxially received in the cavity, a central socket contact on the floor at the axis, and an annular disk separate from the housing, surrounding the central contact. The disk is formed on the axis with a central aperture and is spaced at the aperture substantially further from the floor than the central socket contact. Thus only a lamp base with a central lamp contact on an extension stem can fit in the socket and engage through the aperture and past the disk to make contact with the central socket contact.

  • Expansion valve and method for controlling it
    Patent number: 7487647
    Abstract: The invention relates to an expansion valve and to a method for controlling an expansion valve, in which the opening and closing movement of the valve-closure member is set as a function of the pressure difference which is present in a feed opening on the high pressure side and in a discharge opening.
