The disclosure relates to a compressor assembly for an air supply unit of a vehicle. The compressor assembly includes: a compressor for providing pressurized air and having a compressor housing, at least one mounting bracket, wherein the at least one mounting bracket is fixed to the compressor housing, and, for each mounting bracket, one bearing for connecting the compressor assembly to a housing structure of the air supply unit. The bearing includes a flexible, hollow bellow, adapted to receive a gaseous medium, wherein the bellow includes at least one mounting feature, in particular recess, adapted to receive the mounting bracket, and the bellow is adapted to be pneumatically charged from an unpressurized state into a pressurized state, wherein the mounting feature is adapted to mechanically connect the bellow to the mounting bracket in a pressurized state via a positive lock.

An accumulator fixing device for a compressor includes a bracket body, a first arm portion extending from the bracket body and coupled to an accumulator, and a second arm portion extending from the bracket body and coupled to a housing of a compressor. The bracket body has a cavity formed concavely on one surface facing the compressor to reduce vibration generated and transmitted from the compressor.

A pressurization dehydrator comprising an air compressor and a controller connected to enable automatic operation of the dehydrator. The dehydrator is implemented as a freestanding, bench-top unit having a housing that encloses a baffle plate on which the compressor is mounted. The bottom panel of the housing is affixed to the plate using dumpers inserted therebetween. The plate has legs protruding through the corresponding openings in the bottom panel for supporting the whole unit in the upright position on the bench top. Some or all of the legs may not have contact with edges of the openings. In operation, the legs provide an efficient mechanical pathway for transferring some vibrational energy of the plate to the bench top, thereby diverting said energy away from the housing. The circuit board of the controller is affixed to the housing, which beneficially reduces vibration levels transferred to the electronic components of the controller.

A vibration body unit includes: a vibration body; an inner cylinder that surrounds a circumference of the vibration body and that is elastically deformable; an outer cylinder that surrounds a circumference of the inner cylinder and that has an attachment section which is attached to a base part; a plurality of first spacers that are interposed between the vibration body and the inner cylinder and that are arranged to be spaced in a circumferential direction; and a plurality of second spacers that are interposed between the inner cylinder and the outer cylinder and that are arranged to be spaced in a circumferential direction, wherein the plurality of first spacers and the plurality of second spacers are arranged such that at least part of each of the plurality of first spacers faces each of the plurality of second spacers in a radial direction across the inner cylinder.

An air conditioner unit includes a cabinet including a base pan that defines at least one alignment feature and a compressor mounted to the base pan using mechanical fasteners that pass through mounting feet and into mounting bosses defined on the base pan. A damper is positioned between the compressor and the base pan and includes a lower pad seated on the base pan, an upper pad extending from the lower pad along the vertical direction and contacting a bottom surface of the compressor, and at least one stopping feature defined on the lower pad or the upper pad, the at least one stopping feature engaging the at least one alignment feature to prevent rotation of the damper.

A compressor includes a case, a compression unit having a cylinder, a piston disposed inside the cylinder, and a driving unit for reciprocating the piston, and a support unit elastically supporting the compression unit to be spaced apart from an inner surface of the case. The support unit includes a wire spring having a plurality of linear portions arranged in parallel with one another and curved portions each connecting two adjacent linear portions. The wire spring includes a first wire spring and a second wire spring symmetrically disposed with each other. The wire spring includes a connecting portion connecting the first wire spring and the second wire spring, and the connecting portion is supported by the case. Accordingly, a simplified structure can be obtained and a manufacturing cost can be reduced.

An air pump device includes an electric pump unit including a pump mechanism and a motor configured to drive the pump mechanism, a case housing the electric pump unit, and a vibration-proof member interposed between the electric pump unit and the case. The vibration-proof member is a plate-shaped member made of an elastic resin material and is wound around the electric pump unit to wrap the electric pump unit therein. A part of the vibration-proof member is sandwiched between the electric pump unit and one of facing surfaces that are inner surfaces of the case and face each other inside the case.
