The piston is provided with a pair of radial holes opened to an external circumferential recess and lodging and retaining one respective end of a pin, to which is coupled a driving mechanism to reciprocate the piston inside a cylinder. The radial holes are completely sealed in order that the axial extension of a bottom radial gap provided by a bottom bearing surface of the piston work together with the axial extension of a top radial gap provided by a top bearing surface to provide the required leakage restriction of the refrigerant gas and also the required bearing of the piston inside the cylinder. The axial extension of each of the top bearing surface and of the bottom bearing surface is insufficient to provide by itself said required leakage restriction of the refrigerant gas.

Piston for a reciprocating hermetic compressor

The docking station () comprises a casing () presenting an air inlet () and a cooled air outlet () and housing a refrigeration system () for cooling an air flow which is caused to pass through the interior of the casing (), from the air inlet () to the cooled air outlet (). The refrigeration system () comprises: a compressor () pumping refrigerant fluid through a refrigeration circuit comprising a condenser () and an evaporator () and, preferably, a ventilation means () producing said air flow which is conducted through the evaporator () to be cooled thereby and released, through said cooled air outlet (), to the interior of a computer () seated against the docking station ().

Computer docking station

A mounting arrangement for the piston of a reciprocating hermetic compressor, comprising: a cylinder (), inside which is defined a compression chamber (C); and a piston () provided with a pair of radial holes (), each lodging and retaining one end of a pin (), to which is coupled a driving mechanism of the compressor to reciprocate the piston () inside the cylinder (), said radial holes () being completely sealed in relation to the radial gaps () of the bearing surfaces () of the piston (), so that both radial gaps () operate as means for restraining the leakage of refrigerant gas outwardly and inwardly in relation to the compression chamber (C).

Mounting arrangement for the piston of a reciprocating hermetic compressor

The invention refers to a linear compressor, comprising: a shell (); a cylinder () affixed to the shell () and defining a compression chamber (C); a piston () to be displaced in reciprocating movement in the interior of the compression chamber (C) during the operation of the compressor; a linear electric motor () mounted to the shell (); and an actuating means () operatively coupling the piston () to the linear electric motor (), in order to make the latter displace the piston () in a reciprocating movement in the interior of the compression chamber (C), the actuating means () being coupled to the piston () by an elastic means (), so that the actuating means () and the piston () be displaced in phase opposition during the operation of the compressor.

Linear compressor

A suction valve for a small hermetic compressor formed as a flexible vane having a fixed end portion, a bending median portion and a sealing end portion with the distance between the external edge portion of the vane and an internal edge portion of the vane.

Suction valve for a small hermetic compressor

A heat dissipating system for a hermetic compressor includes a thermal energy transfer duct having a heat absorbing end mounted to the cylinder block of the compressor to absorb the heat generated by the compression of the refrigerant fluid in the cylinder block and a heat releasing end positioned away from the heat absorbing end and away from the cylinder block in order to release the heat conducted from the cylinder block by the transfer duct.

Hermetic compressor with a heat dissipation system

A suction muffler for a small refrigeration system, the muffler including an enclosed equalizing chamber acting upon a tubular connector and a fluid communication between the equalizing chamber and an acoustic chamber. The assembly simultaneously minimizes the noises of gas pulses inside the suction muffler and the pressure differential between the inside and outside of the tubular connector.

Suction muffler for a reciprocating hermetic compressor

A suction muffler for a reciprocating hermetic compressor, comprising a hollow body () provided with a gas inlet and a gas outlet (), which are respectively in fluid communication with the gas supply to the compressor and with a suction side thereof, said hollow body () defining a plurality of chambers comprising an innermost first acoustic chamber () in fluid communication with the gas outlet () of the hollow body (), and a second acoustic chamber () surrounding at least partially the first acoustic chamber () and in fluid communication with at least one of the parts defined by said first acoustic chamber () and by the gas inlet () of the hollow body ().

A suction and discharge valve arrangement for a small hermetic compressor of the type presenting a compression cylinder (), which has an end closed by a valve plate () and which has a suction pipe () adjacent to the valve plate () and substantially orthogonal to the cylinder axis, the valve plate () being provided with a discharge orifice () substantially centralized in relation to the axial projection () of the internal contour of the compression cylinder (), and with at least one suction orifice (), which is internal to said axial projection () of the internal contour of the compression cylinder (), and defining at least part of the extension of a suction passage (P), with an end opened to the inside of the compression cylinder () and an opposite end opened and connected to the suction pipe () by means of a transition portion (T), which is configured to minimize load losses.
