摘要:
The invention relates to an electrical machine (100) having a stator (105), a rotor (110) mounted to be rotatable about an axis of rotation (120) and an air gap (115) for mounting the rotor (110) in the axial direction. The air gap (115) is arranged perpendicular to the axis of rotation (120) between a rotor surface (130) of the rotor (110) and a stator surface (125) of the stator (105).

The invention relates to a metering module (1), in particular for an exhaust gas after-treatment device (2) of a motor vehicle, comprising a metering valve (3) for injecting a liquid medium. The metering valve (3) has a dedicated inflow duct (5) for the medium to be injected, wherein a fresh-air duct (6) in which a return valve (7) is arranged terminates in the inflow duct (5). According to the invention, a throttle valve (17) is dedicated to the return valve (7). The invention further relates to an exhaust gas after-treatment device.

The invention relates to a foil segment bearing, to a method for setting a gap geometry of a foil segment bearing, and to a corresponding production method. The foil segment bearing (100) comprises a bearing backing (101) with a through opening (102), wherein a shaft (103) can be arranged in the through opening such that a gap (S) exists between the shaft and the bearing backing, at least one first and one second bearing segment (105a, 105b) with a respective inner surface (104a, 104b, 104c) which define a bearing surface (F) with an adjustable circumference (U), wherein the bearing segments (105a, 105b) are arranged in the bearing backing (101) at a distance from the shaft (103) such that a gap (S) exists between the shaft (103) and the bearing segments (105a, 105b), a foil arrangement (107; 107a, 107b) which can be arranged in the gap (S) between the inner surfaces of the bearing segments and the shaft (103), and an adjustment mechanism (110) which is set up in order to set a geometry of the gap.
