Abstract: A spiral compressor may include a stationary first spiral member and an orbiting second spiral member intermeshing with the first spiral member. The spiral compressor may include a pendulum slide mechanism that may have an inner ring and a stationary outer ring connected to the inner ring via a plurality of pendulums. The pendulum slide mechanism may include an eccentric member disposed on a radial inside of the inner ring with respect to a central access of the inner ring. The inner ring on an inner circumferential side may be drivingly connected to the eccentric member and on an outer circumferential side may be rigidly connected to the second spiral member. The second spiral member may transmit an orbiting motion in relation to the first spiral member via the pendulum slide mechanism when the eccentric member is driven.

Abstract: A wastegate valve device for a supercharging device may include a valve disc, which is connected to an actuator device via a drive train. The wastegate valve device may include at least one damping element arranged between the valve disc and the actuator device. The drive train may have an inner section, which is arranged inside a fluid path of a driving fluid. The inner section may include a spindle arm, which is connected to a spindle and to the valve disc. The spindle may be connected to an operating arm, which is arranged in an outer section of the drive train. The operating arm may be arranged outside the fluid path, and may be connected to an operating rod, which is connected to the actuator device. The damping element may be arranged in a connection region of the drive train.
