Sliding-vane type pneumatic motor as well as air compressor and internal combustion engine derived from same

Abstract

The invention relates to a sliding-vane type pneumatic motor as well as an air compressor and an internal combustion engine derived from the same. The sliding-vane type pneumatic motor consists of a rotor, a rotor end cover, a leaf spring, a stator with one or more air chambers, a stator end cover, a sliding vane and a sliding vane airtight strip. A rotor unit of the sliding-vane type pneumatic motor rotates reversely to become a sliding-vane type air compressor. The sliding-vane type pneumatic motor is connected with a middle shaft of the sliding-vane type air compressor to form a body of anengine; and the body is externally additionally provided with a supercharger to form the sliding-vane type internal combustion engine.

Description

technical field [0001] The invention relates to a mechanical engine, in particular to a sliding vane air motor, a sliding vane gas compressor and a sliding vane internal combustion engine. Background technique [0002] Known mechanical motor mainly contains piston engine, turbine engine and sliding vane type air motor now. Piston engines are divided into piston internal combustion engines, piston steam engines and piston compressed gas motors. Due to the reciprocating motion of the piston in the cylinder, the piston engine has the disadvantages of large vibration and low speed. Turbine engines are divided into gas turbines and steam turbines. Due to the need for high-pressure and high-speed gas flow to impact the blades to generate power, turbine engines have strict requirements on manufacturing processes and materials, and many high-temperature and high-pressure gases are directly discharged outside the engine, resulting in serious waste of fuel energy. Now known sliding ...

AI Technical Summary

Problems solved by technology

The stator of the single-acting sliding vane air motor is cylindrical, and the rotor is cylindrical. There are sliding vane grooves on the rotor, and the sliding vanes are installed in the sliding vane grooves. The rotor is placed eccentrically in the stator, and the stator end covers are blocked at both ends of the stator. , the rotor, stator, and stator end cover together form a crescent-shaped air chamber. The inner surface of the stator of the double-acting slide vane air motor is elliptical or parabolic, which can form two air chambers that are centrally symmetrical. However, such an inner surface of the stator The shape processing is difficult, and the crescent air chamber formed is small, and the economy is poor

When the rotors of the above two kinds of sliding vane air motors rotate, there is a stroke in which the volume of the sealed space gradually decreases. This gas compression stroke does reverse work, resulting in a decrease in engine efficiency.

The two surfaces of the stator end cover and the rotor end surface of the two kinds of sliding vane air motors are in contact with each other, resulting in excessive friction
