Embodiment Construction

[0047] figure 1 An example of a supercharging device 1 comprising a compressor 30 (in this case a radial compressor), a rotor bearing 40 and a drive unit 20 is shown schematically in a cross-sectional view. Compressor 30 has an optional overrun air recirculation valve (not shown), and air mass flow LM is also indicated by arrows. The so-called supercharger rotor 10 of the supercharging device 1 has a compressor wheel 13 (also called compressor wheel) and a rotor shaft 14 (also called shaft). During operation, the supercharger rotor 10 rotates about a rotor axis of rotation 15 of a rotor shaft 14 . The rotor axis of rotation 15 and at the same time the supercharger axis 2 (also referred to as the longitudinal axis) are shown by indicated center lines and identify the axial orientation of the exhaust gas supercharging device 1 . Here, the supercharger rotor 10 is supported in a bearing housing 41 with its rotor shaft 14 by means of two radial bearings 42 and an axial bearing d...

Abstract

The invention relates to a compressor (30) of a supercharging device (1) for an internal combustion engine, having: a compressor wheel (13) fixed in rotation to a rotor shaft (14); an air supply channel (36) , for delivering air mass flow (LM) to the compressor wheel (13); an iris diaphragm mechanism (50), arranged upstream of the compressor wheel (13) and having a plurality of lamellae (52), and is designed to close or open the diaphragm hole (55), so that the flow cross-section for the air mass flow (LM) flowing against the compressor wheel (13) can be variably adjusted; the housing (60), It at least partially delimits the air supply channel (36), and is arranged and mounted in the housing (60) with the iris type diaphragm mechanism (50); and the actuator (56), which passes through the The opening (63) is mechanically coupled to the iris diaphragm mechanism (50) to actuate the iris diaphragm mechanism (50), wherein the actuator (56) is disposed on the housing (60) such that the opening (63) It is hermetically closed by means of an actuator (56). The invention also relates to a charging device (1).

Description

technical field [0001] The invention relates to a compressor for a supercharging device of an internal combustion engine and a supercharging device for an internal combustion engine. Background technique [0002] Supercharging devices such as exhaust gas turbochargers are increasingly being used to increase the power of internal combustion engines of motor vehicles. Increasingly, this is done with the aim of reducing the overall size and weight of the internal combustion engine for the same power or even increased power, while at the same time reducing consumption and thus CO in accordance with increasingly stringent legal requirements in this regard 2 emission. The principle of action consists in using the energy contained in the exhaust gas flow to increase the pressure in the intake tract of the internal combustion engine so that the combustion chamber of the internal combustion engine is better filled with oxygen from the atmosphere. In this way, more fuel, such as pet...
