  • Patent number: 9689394
    Abstract: A coolant pump includes a rotatable rotor shaft, a pulley wheel which co-rotates with and is supported by the rotor shaft, a pump wheel rotatably supported at the rotor shaft, and an electrically switched wedge-coupled wet friction clutch. The wedge-coupled wet friction clutch comprises a clutch support fixed to the rotor shaft, a clutch ring arranged at a proximal side of the pump wheel, a clutch disk comprising a ferromagnetic element, a static electromagnet which axially pulls the clutch disk to the clutch support into a disengaged position when the static electromagnet is energized, and a wedge coupling mechanism. The wedge coupling mechanism comprises a wedge element and a counter-wedge element which are configured to generate an axial wedge force which axially pushes the clutch disk into an engaged position against the clutch ring when the static electromagnet is not energized and the rotor shaft rotates.

  • Publication number: 20110164995
    Abstract: There is proposed an embodiment of an electric fluid pump of a semi-axial design wherein support ribs (31) are arranged between a radially outer pump housing portion (32) and a first, radially inner motor housing portion (8) that radially surrounds the electric motor (1), wherein the radially outer pump housing portion (32) is formed integrally with the first motor housing portion (8) and the support ribs (31). In this manner, as compared to previously known embodiments, small wall thicknesses of the pump housing can be realized because the support ribs will offer sufficient strength. Thus, the number of component parts and the weight can be reduced.

  • Publication number: 20090155100
    Abstract: The invention relates to an electric fluid pump with a semi-axial construction, in which a motor housing part (9), situated at the pressure end, has a conduction device (42). The conduction device (42) allows an almost completely irrotational flow to be achieved so that the kinetic energy of the tangential component of the flow velocity is converted into pressure energy with negligible friction losses. This feature of the invention increases the efficiency of the fluid pump. The dimensions of the electric motor can therefore be reduced while maintaining the same delivery quantity.

  • Publication number: 20090116981
    Abstract: The invention relates to an electric fluid pump with a semi-axial construction, wherein the pump housing (32, 33, 34) has at least two identical pump housing parts (33, 34). This feature of the invention reduces the number of different components required to manufacture the electric fluid pump and thus reduces costs while achieving a high operating efficiency.

  • Patent number: 6033183
    Abstract: The invention relates to an impeller of a rotary pump having an annular upper part defining a central inlet opening, a drive-adjacent disk-shaped lower part, and a plurality of blades secured between the upper and lower parts. The upper and lower parts are separate parts which secure together. Each blade is integrally formed with either the upper part or the lower part. Every other blade is formed with the upper part, and the remaining blades are formed with the lower part. Each blade has a free edge, remote from a base thereof, which has a projection which extends into a recess or opening formed in the part to which it is not integrally molded. After the upper and lower parts are assembled together, free spaces around the projections are filled with injected plastic, thereby securing the upper and lower parts together and securing the free ends of the blades.
