Abstract
Disclosed is a step-type capacity varying apparatus of a scroll compressor comprising: an orbiting scroll having a first filling portion step-formed with a constant height from an outer end portion of a wrap towards an inner side of the wrap, and a second filling portion extendingly formed at the first filling portion with a certain length from the outer end of the wrap; a fixed scroll engaged with the orbiting scroll by being provided with a stepped low wrap corresponding to the first filling portion and the second filling portion of the orbiting scroll; and an opening/closing unit for opening and closing a passage formed by the second filling portion of the orbiting scroll and the stepped low wrap of the fixed scroll. According to this, a fabrication cost is lowered, a capacity variation width is greatly increased, and an operation is facilitated.
