Title:
SCROLL EXPANDER AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/164609
Kind Code:
A1
Abstract:
A scroll expander (1) is equipped with a scroll-type expansion mechanism (2) that recovers motive power while expanding a refrigerant flowing into an expansion chamber, and a scroll-type sub compression mechanism (3) that compresses refrigerant sucked into a compression chamber by means of the motive power recovered with the expansion mechanism (2), with the expansion mechanism (2) and the sub compression mechanism (3) being integrally formed back-to-back. A high-pressure lead-in hole (52f) that penetrates from the sub compression mechanism (3) side to the expansion mechanism (2) side is formed in the oscillating scroll (52) of the scroll expander (1) as a refrigerant flow path that guides the refrigerant to the expansion chamber of the expansion mechanism (2), and the refrigerant that flows into the expansion chamber of the expansion mechanism (2) flows into the high-pressure lead-in hole (52f) from the sub compression mechanism (3) side, and is guided to the expansion chamber.
