Disclosed is a housing structure including: a housing, a bottom of the housing being provided with a plurality of supporting feet; a supporting component disposed in the housing and configured to support a motor and a rotor of a compressor; and a connecting component, one end of the connecting component being connected to the supporting component, another end of the connecting component being connected to the housing, and a joint of the connecting component with the housing being away from the supporting feet. An air-conditioning unit and a compressor thereof are also provided. In the structure, vibration passes through a transmission path in the housing before reaching the supporting feet, reducing excessive compressor vibration. The transmission path of the vibration in the housing is extended, thereby reducing the vibration transmitted to a whole machine of the air-conditioning unit during operation, ensuring operational reliability of the whole machine.

A closed compressor includes: a compressor body; and a closed vessel in which the compressor body is accommodated and oil is stored. The compressor body has an electric element and a compression element that is driven by the electric element. The compression element has a cylinder block that forms a cylinder, a piston that performs a reciprocating motion in the cylinder, and a crankshaft that actuates the piston. The cylinder block configures a bearing that pivotally supports the crankshaft. The cylinder forms a compression chamber. The compressor body has a support that forms a curved surface. A contact portion, at which the curved surface comes into contact with a receiving surface in the closed vessel, is formed.

A linear compressor includes: a shell; a cylinder provided inside the shell; a frame coupled to an outer side of the cylinder; a piston configured to reciprocate in an axial direction; a motor that supplies power to the piston; and a spring mechanism coupled to the piston. The spring mechanism includes: a support connected to the piston and including a spring support unit having one or more insertion holes; a first coupling protrusion that extends from the rear side of the spring support unit along the edge of the insertion hole; a support cap inserted into the insertion hole and including a second coupling protrusion protruding from the front side of the spring support unit; a first resonant spring inserted into the outer circumferential surface of the second coupling protrusion; and a second resonant spring inserted into the outer circumferential surface of the first coupling protrusion.

A refrigerant compressor includes a hermetically sealed housing and includes a drive unit; wherein the drive unit is arranged in the interior of the housing and is attached, by way of at least one spring element, to at least one mounting region of the housing with mounting action; wherein a first mounting element and a second mounting element are provided; wherein one of the two mounting elements is connected to the drive unit and the other of the two mounting elements is connected to the mounting region. The first mounting element is of sleeve-like form and has an inner wall, and the second mounting element has a bolt-like section, wherein the bolt-like section is received at least in sections in the first mounting element, whereby an overlap region is formed, in which overlap region a gap is formed between the bolt-like section of the second mounting element and the inner wall of the first mounting element.

A linear compressor may include a shell, a shell cover, a compressor body disposed in the shell, and a support device configured to connect the compressor body to the shell cover to prevent the compressor body from contacting an inner peripheral surface of the shell. The support device includes a support spring formed with a hole in a central portion and having a spiral spring arm extending from the central portion to an outer portion, at least a portion of the outer portion being connected to the compressor body, a rigid connection portion spaced apart from the support spring by a predetermined distance, and an elastic connection portion formed to surround at least a portion of a periphery of the hole of the support spring to connect the support spring and the rigid connection portion and coupled to the shell cover.

A sound attenuation arrangement for an inverter cover of an electric compressor, which is characterised in that in addition to fasteners for the inverter cover on the compressor housing of the electric compressor, a sound attenuation means for reducing noise emission via the inverter cover is provided, where the sound attenuation means is made up of a screw with a screw head and a screw shaft, and in that on the screw head a damping element is arranged, where the screw is in contact via the screw shaft with the compressor body, and via the damping element arranged on the screw head with the inverter cover, in a manner that absorbs vibrations.

A vibration isolation system for compactly mounting a vibrating component, such as an air compressor, to an object, such as an air tank, is described. The system may include a rod and bumper system to isolate the vibrations generated by the air compressor from the vehicle or object that it is mounted to. A primary isolation subsystem may include a rod suspension design which consumes significantly less space than existing solutions. The rod is able to achieve equal spring rates in any direction.

A compressor is disclosed. The compressor compressing and discharging a refrigerant sucked into a cylinder includes a cylinder forming a compression space of the refrigerant and having a cylindrical shape; a piston configured to reciprocate in the cylinder along an axial direction and having a cylindrical shape; a suction valve disposed at a front of the piston; a plate disposed in a rear of the piston, the plate comprising a flow groove into which the refrigerant is sucked; and a rod extending along the axial direction, one end of the rod being disposed on the suction valve, and other end of the rod being disposed on the plate.

The invention relates to a refrigerant compressor (1) comprising a hermetically sealed housing (2) and a drive unit which is arranged inside the housing (2) and has a piston-cylinder unit for the cyclical compression of a refrigerant, and an electric motor for driving the piston-cylinder unit, wherein the refrigerant compressor (1) also comprises at least one connection component (4) for attaching the housing (2) to a device in operative connection with the refrigerant compressor (1), preferably to a mounting plate (28) of a cooling device (3), wherein the connection component (4) comprises an inner element (5) and an outer element (6) surrounding the inner element (5), wherein the inner element (5) has a higher rigidity than the outer element (6). According to the invention, recesses (8) are provided in the outer element (6), which run in transverse directions (27), wherein the transverse directions (27) are directed from an outer surrounding surface (26) of the outer element (6) to the inner element (5).

An outdoor unit for an air-conditioning apparatus, having a compressor, a top cover configured to cover an upper surface of the compressor, and a side cover configured to cover a side of the compressor and a side of the top cover, the side cover including a rectangular cutout portion formed in a part of an upper end of the side cover. The outdoor unit has a non-water-absorbent draining element disposed across from a central portion of the top cover to a bottom portion of the cutout portion, and tilts down from the central portion of the top cover toward the bottom portion of the cutout portion.
