Disclosed is a compressor comprising a rotating assembly, which comprises a compressor wheel and a rotor of an electric motor, a stator of the electric motor, a bearing for the rotating assembly, a support that supports the bearing, and a cooling channel for purposes of cooling the electric motor. In accordance with this disclosure, a section of the cooling channel is arranged in the support.

Compressor

Disclosed is a compressor. The compressor has a shaft with a compressor wheel attached to the shaft. The compressor also as an electric motor configured to drive the shaft, and also has an axial air bearing having a spring plate and a cover plate that are attached to a carrier with clips. The clips may be provided as sheet metal strips having a bent end section that is bent over by more than 90° in the shape of a hook.

A radial air bearing device includes a bearing plate, a spring steel sheet, and a bearing receptacle. The bearing plate includes one or more bearing plate parts with an inner main side and two wide sides. First and second retaining lugs are provided on each wide side and are bent to the outside. The spring steel sheet includes one or more spring steel sheet parts. The bearing receptacle includes a recess with an inner wall and a first groove and a second groove which extend outwards from the recess. The first groove is arranged axially offset with respect to the second groove. The bearing plate parts and the spring steel sheet parts are arranged along the inner wall so that the spring steel sheet runs between the bearing plate and the inner wall and so that the first and second retaining lugs engage in the first or second groove.

Radial air bearing device and method for producing a radial air bearing device

A charging device () for an internal combustion engine or a fuel cell, including a compressor () with a compressor housing () and a compressor wheel () arranged therein. The charging device () also includes a shaft () which is coupled to the compressor wheel (), and a bearing housing () which is connected to the compressor housing and in which the shaft () is rotatably mounted. The bearing housing () includes a thrust bearing () for axial mounting of the shaft (). The thrust bearing () has a bearing gap () which extends at least partially in a radial direction () relative to the shaft (). The thrust bearing () is fluidically connected to the compressor () and arranged such that when the compressor () is in operation, a fluid stream from the compressor () flows at least partially in the radial direction () through the bearing gap (). The thrust bearing () is fluidically connected to a pressure side () of the compressor ().

Charging device with thrust bearing

A supercharging device having a housing, at least one impeller, and at least one axial bearing having first and second bearing surfaces. The impeller here forms one of the bearing surfaces of the axial bearing.

Supercharging device

This disclosure relates to an arrangementfor variably adjusting the cross-section of a compressor inlet. Furthermore, the disclosure relates to a charging device having such an arrangement. The arrangementcomprises a compressor housingwith a main bodyand an inlet cover. The inlet coverdefines a compressor inlet. The arrangementfurther comprises an adjustment mechanismwhich is arranged in the compressor housing. The adjustment mechanismcomprises an actuation ringand a plurality of orifice elements. Each orifice elementis coupled to the actuation ringvia a respective coupling elementand is rotatably supported in the compressor housingvia a respective shaft. Furthermore, the arrangementcomprises at least one wear reducing feature providing a wear reduced operation of the adjustment mechanism
