  • Patent number: 11060453
    Abstract: Disclosed is a turbocharger for an internal combustion engine, having a bearing housing. A turbocharger rotor is mounted to be rotatable in the bearing housing about the rotor axis of rotation of its rotor shaft, wherein a turbine wheel is arranged for conjoint rotation on the rotor shaft and in a turbine housing fixed on the bearing housing. Between the rotor shaft and the bearing housing, an oil seal for sealing the bearing housing with respect to the turbine housing is arranged between the turbine wheel and a radial bearing associated with the turbine wheel in order to seal the bearing housing with respect to the turbine housing. A predetermined breaking point is formed for the turbocharger rotor of the turbocharger which lies in a breaking point region and extends axially between the turbine wheel back and an axial end, facing the turbine wheel back, of the rotor-shaft oil seal.

  • Patent number: 8939949
    Abstract: The present disclosure relates to a stacked multi-disk pump for the pumping of ocular fluid and/or tissue during ophthalmic surgery. The stacked multi-disk pump includes an inlet port, a stacked multi-disk assembly, a fluid chamber, a central hub, a motor, and an outlet port. The motor and the hub induce the multi-disk assembly to rotate. As the multi-disk assembly rotates, the fluid is propelled into the inlet port, progresses axially, circumferentially, and radially through the stacked multi-disk assembly, and flows out the outlet port. The pump may be incorporated, for example, into the handpiece of an ophthalmic surgical instrument or a surgical console.

  • Publication number: 20140271284
    Abstract: The preferred embodiments of the present invention provide two advantageous features, which are especially beneficial in combination, but which can be advantageously and beneficially employed independently of one another: (1) firstly, a self-cooling motor bearing system; and (2) secondly, a self-lubricating motor bearing system. In the preferred embodiments, one or both of these two advantageous features are integrated inside an electric motor (e.g., within the electric motor's enclosure housing) in such a manner as to greatly enhance bearing operating conditions (e.g., maintaining adequate bearing lubrication and/or bearing operating temperature) without the use of external lubrication units and/or external cooling units.
