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).
