NOVELTY - The turbine (10) has a stator (40) with a track (16), and a central axis (18) coupled to a base for movement between positions. A rotor (12) is rotatable upon the axis. A set of arc-shaped paddles (14) is pivotally coupled to the rotor at an end and coupled to the track at another end. The paddles comprise a frame and a sail, where the sail comprises a sheet material. A deflector is positioned relative to the rotor for blocking a subset of the set of paddles. The stator includes semi-cylindrical walls spaced from the axis by predetermined radius defining an inlet and an outlet.    USE - Fluid turbine for carrying variable volume of fluid e.g. vapor, steam, liquid fluid and gaseous fluid, and for use as a compressor, pump, motor and clutch (all claimed), in an automotive industry, and for electricity generation. Can also be used in pharmaceutical, petrochemical, mining, air conditioning, laboratory, thermal, wind and hydraulic power generation, thermo-electrical generator, regenerative braking, leverage and mechanics.    ADVANTAGE - The turbine achieves high pressure and temperature differentials than other devices. The rotor is fixed at a floating position to enable movement of the axis versus stator's axis that changes eccentricity of the paddles relative to the track, thus increasing exposed surface area of the paddles at a side of the axis while decreasing area on an opposing side. The turbine allows flow of the fluid to be orientated smoothly and perpendicular to the paddles, so as to drive the turbine in a same way that water drives a watermill, and to enable a radial turbine to be simple, robust and efficient than axial turbines in a similar power range. The turbine maintains power, and efficiency remains almost constant during prolonged service life of the radial turbine. The bearing is placed at two ends of a rotor's shaft, so as to avoide the need of lubrication, and to prevent thermal losses. The turbine prevents requirement of an oil filtering system from being mixed with other chemicals, so as to prevent exploitation of gases. The turbine provides better tightness between the sliding paddles and a stator's wall without the need for seals. The turbine prevents requirement of a spring for the paddles to press against the stator's wall, so as to achieve constant efficiency.
