Abstract
A compressor includes a rotation shaft that is capable of rotating around a main axis, an impeller provided integrally with the rotation shaft, a casing that covers the impeller from an outer circumferential side and forms a flow path through which a working fluid circulates, a discharge scroll that is provided at an end of the flow path on a downstream side and extends in a spiral shape around the main axis, a discharge nozzle that communicates with the discharge scroll on the downstream side and extends from the discharge scroll in a tangent direction around the main axis, and a pressure loss body that has a plate shape extending in a direction orthogonal to an axis of the discharge nozzle extending in a radial direction orthogonal to the main axis and is capable of blocking a part of a flow path cross-section of the discharge nozzle.
