The present invention relates to a suspension disposed between a compression unit and the hermetic housing of hermetic reciprocating compressors for mobile application, such as, for example, application in automotive vehicles and similar, and to the method of assembly of the components that constitute the referred suspension. According to the present invention, it is disclosed a suspension for hermetic reciprocating compressor for mobile application capable of reducing the effects of an eventual and involuntary sudden movement of the compression unit and also of minimizing the transfer of vibrations and noises deriving from the environment outside the hermetic housing to the compression unit.

A linear compressor is provided. The linear compressor includes a shell, a frame disposed in the shell, the frame including a body portion and a first flange portion extending radially from a front of the body portion, a cylinder fixed to the body portion, and a piston disposed in the cylinder and configured to reciprocate axially. The first flange portion includes a hole penetrating a front surface and an inner surface of the first flange portion.

A hermetic compressor is provided. The hermetic compressor may include a compressor body spaced apart from an inner surface of a shell and including a motor unit and a compression unit; at least one support spring provided between the shell and the compressor body and that elastically supports the compressor body with respect to the shell; at least one stopper cap fixed to the inner surface of the shell or the compressor body facing the inner surface of the shell; and a stopper bar that extends from the compressor body or the inner surface of the shell and inserted into the at least one stopper cap with a predetermined distance therebetween. By mechanically restraining vibration of the compressor body and limiting amplitude of the compressor body, vibration noise of the compressor body may be reduced and the compressor body may be suppressed from being in contact with the shell to thereby prevent damage to the compressor body.

An apparatus for connecting a resilient member 1 to a magnetic actuator 2 of a linear compressor. The apparatus includes at least one support member 6 cooperating with a resilient element 1, the support member 6 includes a substantially cylindrical part equipped with intermediate perimeter salient portion 61; at least one fastening element 7 cooperating with the support member 8 and the magnetic actuator 2, and enabling interconnection between a magnetic actuator 2 and a resilient member 1 of a detachable and electrically insulated linear compressor, the fastening element 7 being made in electrically insulating and non-magnetic material.

An air compressor assembly may include a support structure, an operating unit including a compressor operatively connected to a motor through at least one drive belt, and at least one vibration isolator that is positioned between at least a portion of the support structure and at least a portion of the operating unit. The vibration isolator(s) is configured to dampen vibratory energy generated by the operating unit.

A valve unit for a piston compressor includes a housing, in which at least one inlet valve and at least one outlet valve are arranged. The housing includes a first cylinder-head-side surface and a second, cylinder-side surface which is away from the first cylinder-head-side surface. The surfaces extending transversely to a longitudinal axis of the valve unit. A peripheral wall of the housing of the valve unit, and which surrounds the longitudinal axis of the valve unit, includes at least one contact section. The at least one contact section is provided for contact on a contact surface on the cylinder or on the cylinder head and extends obliquely to the longitudinal axis.

A hermetic compressor may include a plurality of springs provided between a compressor body and a shell to elastically support the compressor body and to space the compressor body apart from an inner surface of a shell. A plurality of spring caps fixed to the inner surface of the shell and the compressor body may support ends of each of the plurality of springs. Each of the plurality of springs may be inclined with respect to an axial direction. Transverse stiffness of the support springs may be increased to thereby reduce vibration noise of the compressor body and prevent the compressor body from being in contact with the shell.

An insert of a cartridge for use with a liquid diffusing device is provided. The insert includes a body, an inlet provided in the body to receive diffused liquid generated within the cartridge during operation of the liquid diffusing device, an outlet zone defined at least in part by the body through which to discharge the diffused liquid toward an external environment, and a tortuous passage extending between the inlet and the outlet zone to aid in further reducing an average particle size of the diffused liquid as the diffused liquid moves through the tortuous passage. Removable cartridges for use with a diffusion device are also provided which include such an insert.

During a pressurization stroke of a high-pressure pump, a cylinder inner wall and a plunger receive a fuel pressure from the pressurization chamber. Meanwhile, an upper housing does not receive the fuel pressure from the pressurization chamber, so that its thickness can be made thin. A cylinder is comprised of a bottom portion, a cylindrical portion and a large-diameter cylindrical portion. When inserting the large-diameter cylindrical portion into a large engaging hole, the bottom portion and the cylindrical portion are not brought into contact with a lower housing. A high liquid-tightness between the bottom portion, the cylindrical portion and a small engaging hole can be ensured.

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.
