<p>PROBLEM TO BE SOLVED: To provide a scroll type compressor in which, at normal operation, a wrap end surface is avoided contacting with a mating side end plate and, at high capability operation, the wrap end surface can contact with the mating side end plate.SOLUTION: When refrigerant gas higher than a threshold flows into a pressure pocket 45 via a high-pressure side flow passage 41, the force pressing an orbiting scroll 30 toward a fixed scroll 20 is larger than the force by which the refrigerant gas in compression chambers PR presses the orbiting scroll 30 in a direction separating from the fixed scroll 20. When refrigerant gas lower than the threshold flows into the pressure pocket 45 via the high-pressure side flow passage 41, the force pressing the orbiting scroll 30 toward the fixed scroll 20 is smaller than the force by which the refrigerant gas in the compression chambers PR presses the orbiting scroll 30 in the direction separating from the fixed scroll 20.</p> |
