Abstract
A rotary machine includes a rotor that includes an impeller cap that regulates the movement of an impeller fixed to a rotary shaft that extends in an axial direction about the axis; a housing that covers a rotor; and an inlet guide vane that has a plurality of movable blades that extend from the housing toward an inner side in a radial direction and disposed at intervals in a circumferential direction, in which a blade tip portion, which is a tip end of the movable blade in the radial direction, is disposed on the outer side in the radial direction with respect to an outer peripheral surface of the impeller cap, and the position of at least a part of the blade tip portion in the axial direction overlaps the position of the impeller cap in the axial direction.
Claims5
A rotary machine comprising:
- a rotor that includes a rotary shaft that extends in an axial direction, in which an axis extends, about the axis, an impeller fixed to the rotary shaft, and an impeller cap that is disposed at an end portion of the rotary shaft and regulates movement of the impeller in the axial direction;
- a housing that covers the rotor and has a suction port allowing a working fluid to flow inside the housing;
- and
- an inlet guide vane that is disposed inside the housing on a first side in the axial direction with respect to the impeller, and has a plurality of movable blades that extend from the housing toward an inner side in a radial direction around the axis and disposed at intervals in a circumferential direction about the axis,
- wherein a blade tip portion, which is a tip end of each of the plurality of movable blades in the radial direction, is disposed on an outer side in the radial direction with respect to an outer peripheral surface of the impeller cap, and
- a position of at least a part of the blade tip portion in the axial direction overlaps a position of the impeller cap in the axial direction.
