Abstract: A yoke structure for a compressor is disclosed, which is applied to a scotch yoke type reciprocating compressor. The yoke structure comprises a crankshaft ( 10 ); a crankpin ( 20 ) connected to the crankshaft ( 10 ), to rotate along a predetermined round trajectory which has the crankshaft at its pivot, as the crankshaft rotates; a frame having a pair of slide ways ( 41 ) formed on two parallel inner faces of the frame ( 40 ) opposing each other, one or more pistons ( 30 ) to be fixed to outer faces of the frame outside the slide ( 41 ) ways; a sliding block ( 30 ) positioned between the pair of slide ways ( 41 ) and rotatably connected to the crankpin ( 20 ); and a pair of self-lubricating materials ( 32 ) attached to the sliding block ( 30 ) so as to be in contact with opposing faces of the slide ways ( 41 ).

Abstract: A refrigeration system comprising: a heat absorption unit ( 300 ) for absorbing heat from a peripheral portion to fluid under a predetermined constant pressure; a first compression unit ( 410 ) for sucking the fluid discharged from the heat absorption unit ( 300 ) and compressing; an intermediate cooling unit ( 500 ) for cooling the fluid compressed in the first compression unit ( 410 ); a second compression unit ( 420 ) for re-compressing the fluid discharged from the intermediate cooling unit ( 500 ); a heat radiating unit ( 100 ) for radiating heat from the fluid compressed in the second compression unit ( 420 ) and discharged to a peripheral portion under a predetermined constant pressure; an expansion unit ( 200 ) for lowering pressure of the fluid which passed through the heat radiating unit ( 100 ) by an adiabatic expansion and driving the first and second compression units by work generated from the expansion; and a cooling flow path ( 510 ) for passing the fluid discharged from the expansion unit ( 200 ) through the intermediate cooling unit ( 500 ).

Abstract: A multi-stage compressor is disclosed, which comprises: two motion converters driven by one driving shaft and converting a rotary motion to a straight-line reciprocating motion; first and second pistons ( 62 ) connected to one of the motion converters in opposite directions and moving reciprocatively in a straight line; and third and fourth pistons ( 72 ) connected to the other one of the motion converters in opposite directions, arranged at a predetermined angle with respect to the first and second pistons ( 62 ), and moving reciprocatively in a straight line, and which is characterized in that at least two of the four pistons operate for first-stage compression and at least one of the others operate for second-stage compression.
