摘要：
The present invention provides a scroll expander that is efficient in a wide range of operating conditions by suppressing leakage loss and decreases in recovered power using a simple construction.
In the present invention, a scroll expander includes: an expansion mechanism 5 that is constituted by an orbiting scroll 52 and a first fixed scroll 51, and that recovers power by expanding a refrigerant; and an auxiliary compression mechanism 6 that is constituted by an orbiting scroll 62 and a second fixed scroll 61, and that compresses refrigerant using power recovered by the expansion mechanism 5, characterized in that a tip seal is mounted only to a spiral tooth of an orbiting scroll and a fixed scroll of one of either the expansion mechanism 5 or the auxiliary compression mechanism 6.
