Title:
CENTRIFUGAL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/207950
Kind Code:
A1
Abstract:
This centrifugal compressor is provided with: a diffuser disposed on the outer peripheral side of an impeller; a casing; a scroll flow path which is connected to the exit of the diffuser and formed by a scroll inner peripheral wall and a scroll outer peripheral wall; and a discharge pipe connected to the casing so as to form a discharge flow path for guiding a fluid from the scroll flow path to the outside of the casing. The scroll inner peripheral wall is positioned on the inside radially of the exit of the diffuser. The discharge pipe is disposed such that, when viewed from the axial direction of a rotating shaft, an inner peripheral side region of an inner wall surface of the discharge pipe that is continuous with the scroll inner peripheral wall, at a connecting position of the discharge pipe with respect to the casing, is positioned closer to the end-of-spiral side of the scroll flow path than a first line segment which is a line segment passing the center of the rotating shaft and which is parallel to the central axis of the exit of the discharge pipe.
