Abstract
Exemplary embodiments of the present disclosure are directed to a 2-stage supercharging unit having a housing unit which integrates within it a high-pressure charger and a low-pressure charger. The rotor axes of the two chargers are vertical with respect to the housing unit, which can be screwed directly via the housing base to the side of an internal combustion engine. As a result, increased flexibility is made possible with regard to the connection of the supercharging unit to the cooler and to the internal combustion engine, whereby the structural volume of the supercharging assembly can be additionally reduced.
Claims20
A housing apparatus, comprising:
- a housing casing which surrounds a first cavity and which has multiple side surfaces;
- a volute housing arranged in an interior of the housing casing, said volute housing having a central through opening for accommodating a compressor wheel of a rotor and for supplying air from the first cavity to the compressor wheel arranged in said opening, and having a further opening for discharging flow from the volute housing;
- and
- a housing jacket and a second cavity extending between the housing jacket and the housing casing, the second cavity being at least partially filled with liquid;
- wherein a side surface of the housing casing includes a first opening for a lead through of the compressor wheel to be arranged in the volute housing,
- wherein a side surface of the housing casing includes a second opening for discharging, from the housing casing, the flow out of the volute housing,
- wherein at least one side surface of the housing casing includes a third opening for supplying air into the first cavity in the interior of the housing casing, and
- wherein the liquid is conducted out of a bearing region of the rotor into the second cavity between the housing jacket and the housing casing, wherein the liquid runs down over the housing casing under force of gravity.

An exhaust-gas turbocharger, comprising:
- a housing casing which surrounds a first cavity and which has multiple side surfaces;
- a volute housing arranged in an interior of the housing casing, said volute housing having a central through opening for accommodating a compressor wheel of a rotor and for supplying air from the first cavity to the compressor wheel arranged in said opening, and having a further opening for discharging flow from the volute housing;
- and
- a housing jacket and a second cavity extending between the housing jacket and the housing casing;
- wherein a side surface of the housing casing includes a first opening for a lead through of the compressor wheel to be arranged in the volute housing,
- wherein a side surface of the housing casing includes a second opening for discharging, from the housing casing, the flow out of the volute housing,
- wherein at least one side surface of the housing casing includes a third opening for supplying air into the first cavity in the interior of the housing casing,
- wherein the rotor is vertically arranged and has a turbine wheel,
- wherein a turbine wheel housing is arranged vertically above the housing jacket, and
- wherein a multi-part insulation shell arrangement which is fitted on the housing jacket completely surrounds the turbine wheel housing and leaves free an opening for supplying hot exhaust gases and an opening for discharging hot exhaust gases.

A supercharging assembly, comprising:
- multiple housing casings which each surrounds a first cavity and which have multiple side surfaces;
- a volute housing arranged in an interior of each of the housing casings, said volute housing having a central through opening for accommodating a compressor wheel of a rotor and for supplying air from the first cavity to the compressor wheel arranged in said opening, and having a further opening for discharging flow from the volute housing;
- a housing jacket jointly surrounding the housing casings, wherein a second cavity which is at least partially filled with liquid extends between the housing jacket and the housing casings, and wherein the openings in the housing casings are led out of the housing jacket through corresponding openings in the housing jacket;
- wherein a side surface of each of the housing casings includes a first opening for a lead through of the compressor wheel to be arranged in the volute housing,
- wherein a side surface of each of the housing casings includes a second opening for discharging, from the housing casing, the flow out of the volute housing, and
- wherein at least one side surface of each of the housing casings includes a third opening for supplying air into the first cavity in the interior of the housing casing;
- and
- multiple exhaust-gas turbochargers each with a vertically arranged rotor with in each case one turbine wheel and one compressor wheel;
- wherein turbine wheel housings of the turbine wheels are arranged vertically above the housing jacket, wherein a multi-part insulation shell arrangement that is fitted on the housing jacket completely surrounds the turbine wheel housings and leaves free an opening for supplying hot exhaust gases and an opening for discharging hot exhaust gases.
