<p>PROBLEM TO BE SOLVED: To make a refrigerant gas guided into a cylinder bore through a suction port flow in toward the central axis line of the bore by more widely opening the head of a suction valve which is set correspondingly to the suction port at the center side of the cylinder bore. SOLUTION: The suction valve is arranged to one of image limits comparted by the diametrical line of the cylinder bore, and is composed of the valve head and a neck having a bending part and a junction to the valve head. The distance from the end edge of the valve head to the center of the cylinder bore is set shorter than that from the bending part to the latter.</p> |
