Title: SCROLL COMPRESSOR
Abstract:
A scroll compressor (10) comprises a fixed scroll (51), a movable scroll (52), a crankshaft (30), and a compression chamber (53). The fixed scroll (51) has a discharge port (55) that discharges a fluid from the compression chamber (53). By at least partially covering the discharge port (55), the movable scroll (52) changes a communication area (S), which is the area of a section, within the total area, that contributes to communication with the compression chamber. First through third rotation angle positions (θ1-θ3) are progressively larger in this order. At the first rotation angle position (θ1), the compression chamber (53) and the discharge port (55) begin to be in communication. The communication area (S) increases at a first increase rate (G1) while the crankshaft (30) rotates from the first rotation angle position (θ1) to the second rotation angle position (θ2). The communication area (S) increases at a second increase rate (G2) while the crankshaft (30) rotates from the second rotation angle position (θ2) to the third rotation angle position (θ3). The second increase rate (G2) is greater than the first increase rate (G1).
