Title:
FLUID MACHINE
Document Type and Number:
WIPO Patent Application WO/2012/173123
Kind Code:
A1
Abstract:
The present invention relates to a fluid machine wherein operation of each rotation unit can be assessed individually, the length in the axial direction can be reduced, and the number of component parts as well as the number of steps for manufacture and assembly can be reduced. This pump-integrated expander (29A) comprises: a pump unit (60) which rotates around a rotation shaft (28); and an expansion unit (50) provided with a swirling scroll (52) linked to the rotation shaft (28) via a driven crank mechanism (81). In the pump unit (60), a casing member (65) supports a gear pump (61), the rotation shaft (28), and the driven crank mechanism (81), and in the expansion unit (50), a housing constituted by a main body part (51a) and a casing member (54) supports an expander (23) constituted by a stationary scroll (51) and the swirling scroll (52). The pump-integrated expander (29A) can be divided into the pump unit (60) and the expansion unit (50) by separating at a portion where a tubular part (65c) on the pump unit (60) side and a small-inner diameter part (54b) on the expansion unit (50) side are fitted to each other, and pulling out an eccentric bush (83) from a drive bearing (56).
