A reciprocating compressor is provided that may include a shell including a vibration absorbing member formed to be wound around an outer circumferential surface or an inner circumferential surface or stacked thereon, so that compressor vibration may be attenuated by frictional contact between the shell and the vibration absorbing member or between layers of the vibration absorbing member. Also a noise insulating layer may be formed between the shell and the vibration absorbing member or between the layers of the vibration absorbing member, so that a magnitude of noise may be reduced as vibration noise passes through the noise insulating layer, whereby vibration noise of the compressor, such as noise of a high frequency band, may be further attenuated by fine vibration.

In the two-cylinder hermetic compressor, a main bearing is disposed on one surface of a first cylinder, an intermediate plate is disposed on another surface of the first cylinder, the intermediate plate is disposed on one surface of a second cylinder, and an auxiliary bearing is disposed on another surface of the second cylinder. A shaft is constituted by a main shaft portion which has a rotor attached thereto and is supported by the main bearing, a first eccentric portion having a first piston attached thereto, a second eccentric portion having a second piston attached thereto, and an auxiliary shaft portion supported by the auxiliary bearing. A thrust receiving portion is provided on a side of the second eccentric portion facing the auxiliary shaft portion, and the auxiliary bearing is provided with a thrust surface on which the end face of the thrust receiving portion slides while contacting therewith. The thrust surface is provided with a ring groove.

A device for driving a compressor of a gaseous fluid, in particular an electric motor. The device comprises a rotor and a stator which are disposed extending along a common longitudinal axis. A carrier element is disposed in contact on a first end side, oriented in an axial direction, of the stator, which carrier element comprises at least one resiliently deformable pressure element with a contact region. The pressure element is developed extending with an extent in the axial direction and, in a mounted state of the device, is in contact with the contact region on a mating surface under resilient deformation. A method for mounting and a use of the device is also provided.

A rotary compressor, a method of manufacturing a rotary compressor, and an apparatus for manufacturing a rotary compressor are provided. The rotary compressor may include a case having an inner space, a stator to which power may be applied, the stator being disposed in the case, and a compression mechanism disposed on or at one side of the stator to generate a compression force of a refrigerant. The compression mechanism may include a rotational shaft, a cylinder that accommodates a roller coupled to the rotational shaft, a main bearing coupled a first side of the cylinder, and a sub bearing coupled to a second side of the cylinder. The main bearing may be press-fitted and fixed to an inner surface of the case.

A connecting structure, an exhaust silencer, a silencer and a compressor are provided. The connecting structure has a connecting housing and an exhaust pipe assembly. The connecting housing has a silencing chamber and a sealing portion. One end of the exhaust pipe assembly passes through the sealing portion and extends into the silencing chamber. Another end of the exhaust pipe assembly is arranged outside the connecting housing. Thus, the silencing chamber is in communication with an outside space of the connecting housing through the exhaust pipe assembly.
