Document Type and Number:
WIPO Patent Application WO/2018/159143
Kind Code:
A1
Abstract:
The present invention promotes the miniaturization of a scroll type fluid machine. This scroll type fluid machine is provided with: a driving shaft 410 driven to rotate; a crank pin 420 eccentrically fixed to one end surface in an axial direction of the driving shaft 410; an eccentric bushing 430 eccentrically fixed to the crank pin 420 so as to be rotatable relative to the crank pin 420; a rotating scroll fixed to the eccentric bushing 430 so as to be rotatable relative to the eccentric bushing 430; and a fixed scroll engaged with the rotating scroll. Also, a projection 430A, which extends from one end surface of the eccentric bushing 430 toward the driving shaft 410 and contacts a portion of an outer circumferential surface of the driving shaft 410, is formed on the one end surface of the eccentric bushing 430. Also, the driven amount of the rotating scroll with respect to the driving shaft 410 is restricted by the projection 430A.
