  • Patent number: 11898569
    Abstract: A fan includes a hub configured to be driven by motor to rotate about a fan rotational axis, blades that protrude radially from the hub and a band that surrounds the rotational axis and connects the tips of the blades. The band includes structurally-reinforcing ribs that protrude from the hub-facing surface of the band. A rib is disposed between respective tips of each pair of adjacent blades. Each rib bridges a knit-line of the band, and has a circumferential dimension that is at least 40 percent of a distance between the respective tips of the adjacent blades.

  • Publication number: 20140246803
    Abstract: Equipping engine cooling fans with flaps, in particular ram-air flaps, which are opened by the relative wind and can close again by means of gravity at a vehicle standstill, is known. Until know, it has been common to install such ram-air flaps manually on a frame of the engine cooling fan. However, all of said embodiment concepts require complex motion guidance during the installation in/on the frame.

  • Publication number: 20140086722
    Abstract: An assembly for increasing air flow to a vehicle cooling system includes a portion of a cooling fan shroud, the portion having a face defining an opening therethrough, and a plurality of support members extending from the face. A flap includes a plurality of apertures proximal to an edge. Each aperture of the plurality of apertures is formed to receive one of the plurality of support members for coupling the flap thereto. A clearance fit formed between the apertures and the support members permits movement of the flap from a first position generally parallel to the face to a second position in response to a flow of air.

  • Publication number: 20130328229
    Abstract: A process is described for producing an injection moulding (300) with the aid of an injection moulding device (100), where a charge (301) is injected into a cavity (200) of the injection moulding device (100) and is foamed with the aid of a ventilation cycle (132, 142, 152). In this process, a displacer element (130, 140, 150) restricted to a selected section (220, 240, 260) of the cavity (200) is introduced into the cavity (200), and the charge (301) is injected into the cavity (200) with the displacer element (130, 140, 150) arranged therein. In a subsequent ventilation cycle (132, 142, 152), the displacer element (130, 140, 150) is then moved out from the cavity (200) in order to foam the charge (301) in the selected section (220, 240, 260) of the cavity (200).

  • Patent number: 7166940
    Abstract: An external rotor motor is disclosed, which features a stator (11) and a rotor (13) surrounding the stator (11) while leaving an air gap. A damper (16) made of an elastic material is arranged on the outside of the rotor (13) in order to dampen resonant rises in airborne sound, which is emitted by the rotor of the external rotor motor and by an assembly coupled to it. In the case of a rotor (13) that is designed to be pot-shaped, the damper (16) is preferably embodied as a damping cap (17), which surrounds the pot jacket (132) and at least partially covers the pot base (131) (FIG. 1).
