Abstract:
A fluidal machine comprising:an impeller rotationally arranged to urge a fluid radially outwardly by a centrifugal force, a plurality of vane members configured to the fluid discharged from the impeller, including a first vane member, each of the vane members comprising a front end arranged to face the impeller so that the fluid discharged from the impeller strikes against the front end and which is prevented from communicating with atmosphere, and a casing surrounding the vane members and communicating with the atmosphere, wherein at least one of the first vane member and the casing has an elastically deformable portion connected to the other of the first vane member and the casing to obtain a decreased connecting rigidity between the first vane member and the casing in at least one of an impeller axial direction, an impeller radial direction and an impeller circumferential direction, and wherein the at least one of the first vane member and the casing has a pin connected to the other of the first vane member and the casing, and the pin includes the elastically deformable portion through which a deformation of the vane member is transmitted to the casing.
