<p>PROBLEM TO BE SOLVED: To cut a pulsation component in a high frequency region so as to reduce noise by disposing an extending device for extending a passage length in an intake port in a compressor in which refrigerant gas taken inside a cylinder bore by pushing and opening an intake valve is compressed, and then, the compressed refrigerant gas is discharged by opening a discharge valve. SOLUTION: When a rotating motion of a swash plate 19 ratable together with a drive shaft 16 is converted into a reciprocating linear motion of a piston 21, refrigerant gas pushes and opens an intake valve 14c via an intake port 14a to be taken into a cylinder bore from an intake chamber 13a. Subsequently, the refrigerant gas after compressed is discharged to a discharge chamber 13b while pushing and opening a discharge valve 14a via a discharge port 14b. In this case, a cylindrical passage 34 having a predetermined length is connected to the intake port 14a, thereby extending the passage length of the intake port 14a. The intake chamber 13a of a predetermined capacity is connected to the rear end of the cylindrical passage 34. Consequently, in the case where intake pulsation is generated during a compressing operation, a pulsation component in a high frequency region can be effectively cut, so that noise can be reduced.</p> |
