The present invention provides a horizontally opposed compressor that sufficiently secures the
stroke of the
piston, arranges each compression section in a balanced manner, is small in size, and has little vibration. The compression part (6, 25) is connected to the eccentric part (3C, 3D) at a position away from the middle position (M) of the
crankshaft (3) by the dimension (L1), and the inner
diameter (A) of the cylinder (7, 26) and the
piston The strokes (S) of (16, 27) are equal. In addition, the compression part (21, 29) is connected to the eccentric part (3C, 3D) at a distance (L2) from the middle position (M), and the inner
diameter (A) of the cylinder (22, 30) and the
piston (23, 31 )
stroke (S) equal. Accordingly, a balancer or the like is unnecessary, and the compressor can be reduced in size and weight, and vibration can be reduced. Furthermore, since the respective connecting rods (17, 24, 28, 32) can be connected to the
crankshaft (3) with the axial positions of the pistons slightly shifted, the
stroke (S) can be sufficiently ensured even in a compact arrangement.
