Compressor

Abstract

A compressor comprises a sealed housing and a driving unit arranged inside the housing. At least one damping device for suppressing and limiting a deflection of the driving unit is provided inside the housing. The damping device is connected to the driving unit. The damping device has a first contactable region facing and at a distance from an inner surface of the housing. The housing comprises a second contactable region corresponding to the first contactable region of the damping device. The second contactable region comprises an inner surface and an outer surface. The shape of the second contactable region of the housing matches the shape of the first contactable region of the damping device. The first contactable region of the damping device comprises at least an arc-shaped circumferential contactable region. The damping device reduces the noise and damage that may occur as a result of the deflection of the driving unit and improves the stability of the driving unit.
