PROBLEM TO BE SOLVED: To suppress degradation of efficiency of a compressor, in the compressor in which a lubricant is introduced to a dead volume such as a discharge port (21b) and the like as a space in which a gas remains in a compressing mechanism (20) in completing a discharge process, and the lubricant is supplied to a cylinder chamber (25) in starting compression to reduce pressure pulsation.SOLUTION: An oil storage recessed portion (43) for temporarily storing a lubricant introduced to a cylinder chamber (25) from an oil reservoir (14) of a casing (10), is formed in the cylinder chamber (25), and a volume of the oil storage recessed portion (43) is determined so that the lubricant introduced to a dead volume becomes less than the amount to fill the dead volume. |
