PROBLEM TO BE SOLVED: To improve controllability by reducing the flow amount of refrigerant gas to flow as blow-by gas into a crank chamber while passing between a piston and a cylinder bore.SOLUTION: In a cylinder block 11, a communication passage 51 which communicates between adjacent cylinder bores 11a is formed in a region between a compression chamber side end face 30e of a piston 30 when a piston 30 reaches a top dead center position P1 and a compression chamber side end face 30e of the piston 30 when the piston 30 reaches a bottom dead center position P2 during a time when the angle of inclination of a swash plate is the maximum. |
