Abstract
A compressor that allows a discharge port to assume a large circumference and a large area at an exit end thereof so as to optimize the discharge resistance and the pressure-receiving area and assuring improved volumetric efficiency through reduced dead volume, includes a discharge port 5b, an entrance end of which opens into a compression chamber and an exit end that is able to open and shut with a discharge valve 43. The discharge port 5b is constituted with a recessed portion 50 formed to achieve a predetermined depth from the exit end and a through portion 51 having a smaller sectional area than the sectional area of the recessed portion 50. The through portion 51 is formed so that its width measured along a direction perpendicular to the longitudinal direction of the discharge valve is greater than its width measured along the longitudinal direction of the discharge valve 43.
