Embodiment Construction

[0057] 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 schematically shown in a 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 charger rotor 10 of the charging device 1 has a compressor wheel 13 (also called compressor wheel) and a rotor shaft 14 (also called shaft). The supercharger rotor 10 rotates during operation 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 the indicated center lines and identify the axial orientation of the supercharging device 1 . The supercharger rotor 10 is installed, wherein the rotor shaft 14 of the supercharger rotor 10 is situated in the bearing housing 41 via two radial bearings 42 and an axial b...

Abstract

The invention relates to a compressor ( 30 ) for a charging device ( 1 ) of an internal combustion engine, the compressor ( 30 ) having: - a compressor housing ( 31 ), wherein the compressor wheel ( 13 ) is rotatably coupled Arranged on the rotor shaft (14); - an air feed channel (36) for directing the air mass flow (LM) to the compressor wheel (13). The compressor (30) has a throttle module (70) with: - an iris diaphragm mechanism (50) arranged upstream of the compressor wheel (13) and has a plurality of lamellae (52) and is designed to close or open the diaphragm orifice (55) through the lamellae (52), allowing variable adjustment of the air mass flow (LM) into the compressor wheel (13) flow cross-section; - a throttle module housing (71) at least partially delimiting the air feed passage (36) and on which the iris diaphragm mechanism (50) is arranged and mounted in and / or on the throttle module housing (71); and - the actuator (56) mounted on the throttle module housing (71) And mechanically coupled to the iris diaphragm mechanism (50) to actuate it. The throttle module (70) is formed as a structural unit which is separated from the compressor housing (31) and is flange-mounted on the compressor housing (31) via the throttle module housing (71). The invention also relates to a throttle module (70) and a charging device (1).

Description

technical field [0001] The invention relates to a compressor for a supercharging device of an internal combustion engine, a throttle module for a compressor of a supercharging device, and a supercharging device for an internal combustion engine. Background technique [0002] Supercharging devices such as exhaust-gas turbochargers are increasingly used to increase the power in internal combustion engines of motor vehicles. More and more frequently, the aim is to reduce the overall size and weight of internal combustion engines of the same power or even higher power, and at the same time reduce consumption and thus CO 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 and thus to better fill the combustion chamber of the internal combustion engine with oxygen from the atmosphere. In this way, more fuel, such as petrol or diesel, can be converted per ...
