Abstract
PURPOSE: To reduce the axial length of a shaft seal, by providing an equal pressurizing groove of reduced axial width on an annular equal pressurizing passage block between and end wall and a shaft seal ring so that the depth of the groove extends in the radial direction of the block.
CONSTITUTION: A groove D is provided on a passage block 7 mounted on an end lid 2 by bolts 8. A drilled hole E extends from the groove D in the axial direction and coincides with a drilled hole of the end lid 2 so that these drilled holes communicate with each other. The groove D communicates with chambers a, b, c between fins through holes of a shaft seal ring 4. As a result, the axial length of a hole G of the end lid 2 does not need to be larger than the width S of the groove D, as against a conventional olique hole. Therefore, the axial length of a shaft seal and the length of a rotor between bearings are reduced.
