Abstract: A compressor includes a sealed casing (2) which accommodates therein a compressing unit (6) for compressing a refrigerant and a driving unit (7) for driving the compressing unit. An induction pipe (18) is provided in the sealed casing for introducing the refrigerant into the compressing unit. The induction pipe has an outlet end communicating with the interior of the compressing unit and an inlet end which is opened to space in the sealed casing at a position which may correspond to a node of a standing wave of the refrigerant in the sealed casing.

Abstract: The same number of grooves 20 through 27 are provided in end surfaces 19a and 19b of a roller 19. The grooves 20 through 27 have communicating portions 20a through 27a which communicate with an inner peripheral side of the roller 19 and sealed portions 20b, 20c, 20d, 20e, 20f through 27b, 27c, 27d, 27e and 27f whose crosssectional area decreases. Accordingly, the crosssectional area is decreased in a direction in which a lubricating oil flows, and a plurality of oil pressures can thus be obtained. This makes a clearance of the roller 19 fixed.
