Abstract: The invention relates to a compressor, in particular a gas compressor, for instance for a turbocharger, for compressing a gaseous fluid, having a compressor housing (40) in which a compressor wheel (41) is rotatably arranged, wherein the compressor housing (40) has a gas intake manifold (43), via which gas can be fed to the compressor wheel (41), a compressor duct (42) being provided, via which the compressed gas can be discharged from the compressor wheel (41), an adjustment device (60) being arranged in the area of the gas intake manifold (43), wherein the adjustment device (60) has orifice elements (70), which can be adjusted linearly between a closed position and an open position, and by means of which the opening cross-section of the gas intake manifold (43) in a duct area can be varied in order to form a minimum opening cross-section (Ömin) in the closed position and a maximum opening cross-section (Ömax) in the open position, wherein in each case two adjacent orifice elements (70) have sealing segments

Abstract: A bearing housing for an exhaust gas turbocharger may include a bearing housing cover arranged on a bearing housing wall. The bearing housing cover may include a penetrating rotation-symmetrical sealing recess with a centre axis and may have a locating surface facing the bearing housing wall and radially extending from the centre axis. The bearing housing may include a sealing bush arranged in at least one region of the sealing recess. The sealing bush may have a stop surface arranged opposite the locating surface and may include a penetrating shaft recess disposed rotation-symmetrical relative to the centre axis. The bearing housing cover may further include an at least partly circulating groove disposed on the locating surface radially spaced from the centre axis. The groove may include a drainage region arranged below the centre axis and extending from the centre axis radially to an outside.

Abstract: The present disclosure relates to a compressor for compressing charge air for a combustion engine. The compressor comprises charge air inlet for the through-flow of charge air in axial direction, in which an adjustment device for adjusting a diameter of the charge air inlet is fixedly arranged. The adjustment device comprises a ring-shaped radially arranged guidance arrangement and aperture elements movably mounted in the guidance arrangement, wherein the aperture elements can be adjusted at right angles to the axial direction by the guidance arrangement in at least two closed positions. With this arrangement the diameter of the charge air inlet varies in the respective closed positions. The aperture elements are arranged in a common radial aperture plane and are supported against each other in the respective closed positions in the circumferential direction.
