ABSTRACT:
With a turbine of the present invention, a preferably spiral partition is formed upright on the outer periphery of a rotor carried rotatably in a casing. A large number of blades are mounted between turns of the partition at a predetermined interval on the outer periphery of the rotor, and a channel for the working fluid is formed in the space between the blades and the partition on the outer periphery of the rotor.
Therefore, the turbine of the present invention is a highly efficient turbine capable of efficiently utilizing even a low pressure low speed low flow rate working fluid, while being capable of efficiently converting the kinetic energy of the working fluid into the rotational force of the rotor and realizing a low speed high torque rotation.
A turbocharger making use of the turbine is capable of performing sufficient supercharging not only during high speed rotation but during low speed rotation of the engine, while being preferably capable of cleaning emission gases.
