Abstract: In a double rotation type scroll expander having double expansion chambers, a single integrated drive shaft is disposed to penetrate the interior of a housing, the double expansion chambers are formed by a drive scroll body and a driven scroll body, and a working medium introduction hole is provided in an axial direction of the drive shaft such that the working medium is supplied evenly to the double expansion chambers through the working medium introduction hole via a radial direction hole. The drive shaft and the drive scroll body formed integrally with the drive shaft rotate while the driven scroll body rotates synchronously with the drive scroll shaft via an interlocking mechanism.

Abstract: A scroll fluid machine includes fixed and orbiting scrolls which define a compression chamber; a land which divides the compression chamber into first-stage and second-stage compression chambers; a wrap groove defined in a spiral shape along a tip of a fixed wrap of the fixed scroll; an intermediate groove defined in the land; a seal member; and an intermediate seal member. The land includes a first-stage outlet in communication with the first-stage compression chamber and a second-stage inlet in communication with the second-stage compression chamber. The wrap groove includes an outer peripheral wrap groove adjacent to the land on a radially outward side and an inner peripheral wrap groove adjacent to the land on a radially inward side. The intermediate groove is in communication with the outer and inner peripheral wrap grooves. The seal member is fitted in the wrap groove except the outer and inner wrap grooves.

Abstract: A seal groove is cut in the distal end face of a wrap of a fixed scroll, with a tip seal being fitted in the seal groove. Swelling members are interposed between both side faces of the tip seal and corresponding opposite side faces of the wrap. Condensed liquid of working medium w and water condensed from steam contained in the working medium w that are present between the tip seal and an end plate provide a sealing effect. When the swelling members swell upon absorbing the condensed liquids, they exert a strong pressing force on the tip seal and the wrap, thereby firmly retaining the tip seal in position. This prevents the tip seal from being pressed against the end plate, so that wear of the tip seal is reduced.

Abstract: Provided is a double rotation type scroll expander, aiming at protecting a bearing that supports drive shaft a drive shaft and the like from the heat of a working medium when a working medium introduction hole is provided in the drive shaft. The working medium introduction hole is drilled into the drive shaft such that the high-temperature, high-pressure working medium is supplied to expansion chambers through the working medium introduction hole. An adiabatic sleeve that forms a part of the working medium introduction hole is attached to the drive shaft in an internal region of roller bearings that support the drive shaft and a driven scroll body rotatably. Heat transfer from the working medium to the roller bearings is suppressed by the adiabatic sleeve, whereby the roller bearings are prevented from deteriorating.
