WIPO Patent Application WO/2017/007195
Kind Code:
A1
Abstract:
A free-turning fluid machine, according to the present invention, comprises: a main body having a hollow cylindrical shape, the inner circumferential surface of which is formed in an elliptical shape; a rotor provided inside the main body and rotating about the same center of rotation as that of the main body; tip seals, each being provided at one side of the rotor to make contact with the inner circumferential surface of the main body; and blades, each being provided between the tip seals adjacent to each other and supported by the tip seals, wherein each blade has one surface facing the inner circumferential surface of the main body and an opposite surface opposite to the surface of the blade, and the centers of curvature of the opposite surfaces may be located on the same side. As described above, the spaces between the inner circumferential surface of the main body and the rotor and tip seals are sealed by auxiliary tip seals so that it is possible to prevent leakage of an introduced working fluid, as well as reducing friction between the tip seals and the main body.
