PURPOSE:To provide an arrangement for a compressor capable of increasing the compression ratio although its structure is rather simple, by providing a sliding plate which is inserted into a turning shaft disposed eccentrically in a hollow chamber, in the manner that it divides the hollow space into two sections and is slidable in a direction perpendicular to the axis of the turning shaft. CONSTITUTION:A turning shaft 5 is held in contact with the inner wall surface 21 of a hollow chamber 2 at an intermediate portion between an inlet port 3 and an outlet port 4, so that the two ports 3, 4 are separated from each other by the turning shaft 5. A sliding plate 6 is fitted into the body of the turning shaft 5 in a direction perpendicular to the axis of the shaft 5, and its opposite end portions are held in light contact with the inner wall surface 21 of the hollow chamber 2. Here, arrangement is such that the sliding plate 6 slides perpendicularly to the axis of the turning shaft 5 to vary the length of projections of two plate surfaces 61, 62 on the opposite sides of the center of rotation of the turning shaft 5, alternately along with rotation of the shaft 5, so that work fluid can be drawn from the inlet port 3 and discharged from the outlet port 4. |
