  • Patent number: 10046385
    Abstract: The present invention provides a die cast component, in particular a water outlet fitting, containing a base body (1) produced from metal or a metal alloy by the die casting method and having a cavity in which a number of openings (2, 3, 4) are provided by which the cavity is accessible from the outside, the cavity being at least partially filled with a casting core (5) that is in two-dimensional contact with the inside of the base body (1) and in which at least one channel (6) is provided for the conveyance of fluid, the casting core (5) being made of a material the melting point of which is lower than the melting point of the material from which the base body (1) is produced, and that the outside of the casting core (5) rests with at least substantially all of its surface against the inside of the base body (1). Furthermore, the invention also provides a method for producing this type of die casting component.

  • Publication number: 20130299027
    Abstract: The present invention relates to a die cast component, in particular a water outlet fitting, comprising a base body produced from metal or a metal alloy by the die casting method and having a cavity in which a number of openings are provided by means of which the cavity is accessible from the outside, the cavity being at least partially filled with a casting core that is in two-dimensional contact with the inside of the base body and in which at least one channel is provided for the conveyance of fluid, wherein in a predominant part of the contact surface, in particular in the entire or almost the entire contact surface region between the casting core and the base body, the wall thickness of the casting core is as great as or greater than the wall thickness of the base body. Furthermore, the invention relates to a method for producing this type of die casting component.

  • Publication number: 20080302203
    Abstract: The invention relates to a shift lever arrangement for a transmission of a motor vehicle having a shift lever for setting a selected shift stage of the transmission, with the shift lever being mounted, by means of a positioning unit, so as to be movable between a non-use position of the shift lever and a use position thereof for setting the shift stages and/or vice versa, wherein an anti-trap unit is assigned to the shift lever, in such a way that, after the activation of the positioning unit for adjusting the shift lever between the non-use position and the use position thereof and/or vice versa, the positioning force generated by the positioning unit and acting on the shift lever can be at least reduced.

  • Publication number: 20080264193
    Abstract: A shift device for a transmission of a motor vehicle has a shift lever that can be moved into different shift positions, an actuating unit that, as a function of the shift position of the shift lever, generates a shift signal for transmitting to an electric transmission control unit, and an electric transmission control unit that, as a function of the shift signal of the actuating unit, sends an electric activation signal to a shift element of the transmission in order to set the desired shift stage. The actuating unit includes a restoring element or restoring elements operating in such a way that the shift lever, after reaching the selected shift position, is always moved automatically into a predefined starting position.

  • Patent number: 6491505
    Abstract: An electric air-pump apparatus for motor vehicles has a mounting plate to which a housing of an electric motor and a pumping device are attached. A sound absorber is, formed by the mounting plate and a sound-absorber cap attached thereto, with the sound-absorber cap surrounding the pumping device. The sound-absorber cap is positioned on a first side of the mounting plate opposite from a second side of the mounting plate at which the electric motor is to be attached.
