    摘要： A scroll compressor having an improved compression efficiency by optimizing a step mesh gap in an operating state is provided. The scroll compressor having a step-like shape has a step-mesh-gap set value (Hf) occurring between step side surfaces of a connecting wall 12h of a fixed scroll 12 and a connecting edge 13e of a revolving scroll 13 and a step-mesh-gap set value (H0) occurring between step side surfaces of a connecting wall 13h of the revolving scroll 13 and a connecting edge 12e of the fixed scroll 12, and a fixed-side set value (Hf in the example shown in the drawing) for when the two move close together due to the revolving scroll tilting by receiving gas pressure during operation is set greater than that (H0 in the example shown in the drawing) for when the two move apart.

    摘要： A scroll compressor comprising a stationary scroll and a revolving scroll, the stationary and revolving scrolls having end plates with a level difference therebetween such that the height increases along the convolutions of the wall toward the center and decreases toward the outer peripheral end, the upper edge of the wall being of stepped shape corresponding to the level difference between the end plates, wherein a clearance is formed between the upper edge of the wall and each end plate and the height of the clearance is greater at the room temperature than during operation. Further, the level difference is provided at a position beyond a traveling angle π (rad) from the outer peripheral end along the direction of convolutions. Further, the end plate of the stationary scroll is formed with a recess, in which a delivery valve is installed. Further, a plate movable in the direction of the axis of revolution of the revolving scroll is installed and a pressing means for pressing the plate is provided. Further, the shape of a connecting wall surface connecting the adjoining ones of the surfaces of the individual end plates is determined by an envelope described by the revolving locus of a connecting edge connecting the adjoining ones of the individual upper edges. Further, there is provided a communication passage which establishes communication between two compression chambers defined by contact between the connecting edge and the connecting wall surface.
