Abstract

Official abstract text for this publication.

A compressor is provided with a substantially tubular compressor casing, a substantially circular lid that is provided inside an inner periphery of the compressor casing so as to close off an end surface of the compressor casing, a space that is enclosed by the lid and an inner circumferential surface of the compressor casing so as to accommodate a blade, and seal member that is provided in a circumferential direction on the space side of an outer circumferential surface of the lid, wherein a slit part is provided on the lid, radially inside the outer circumferential surface, where the seal member is provided, so as to extend in the axial direction from the space side of the lid.

First claim

Opening claim text (preview).

The invention claimed is: 1. A compressor comprising: a substantially tubular compressor casing; a substantially circular lid that is provided inside an inner circumferential surface of the compressor casing so as to close off an end of the compressor casing; a space that is enclosed by the lid and the inner circumferential surface of the compressor casing and that accommodates a blade; and a seal member that is provided to extend in a circumferential direction on an outer circumferential surface of the lid which is adjacent to the space, wherein a slit part is provided in the lid so as to be located radially inside the outer circumferential surface where the seal member is located, the slit part is configured to extend in an axial direction of the lid from the space side of the lid.
