Abstract

The creation was a compressor with a hollow rotor and specific contours of the stator and the front cover. The features of the compressor were that a stator inner contour was designed by using the triangle function and the inverse triangle function, that an elliptical cam and a vane sliding slot developed using the envelop theorem were designed on the stator, that the front cover had a same vane sliding slot, that a hollow rotor with two slots was installed between the stator inner contour and the elliptical cam, that two vanes with a pin on both sides of each vane were inserted, respectively, in the slots of the hollow rotor. A bearing was mounted on each pin, that the bearings were inserted into the vane sliding slots of the stator and the front cover. The distance between the stator inner contour and the elliptical cam was constant. The top and bottom ends of the vanes were contacted slightly with the stator inner contour and the elliptical cam, respectively. When the rotor started to rotate or lowered the rotational speed, the chance of collision between the vanes and the stator inner contour and the elliptical cam was reduced to protect the vanes, and the gas volume flow rate and the gas pressure were stabilized. The outer cylinder of the rotor, the stator inner contour, the front cover and the vane formed an outer gas chamber. The inner cylinder of the rotor, the elliptical cam, the front cover and the vane formed an inner gas chamber. The design of the hollow rotor increased the available space inside the stator and the gas volume flow rate. When the rotor rotated, the vanes slide along the stator inner contour to change the volumes of the gas chambers. The gas flowing into the gas chambers was compressed. The compressed air flew out of the outlet ports of the stator without valves. The inlet ports and the outlet ports were all designed on the stator to reduce the occupied spaces of the pipes and the compressor.

The present invention is a compressor having a hollow rotor and a special profile part, characterized in that both ends of the sliding blade are in contact with the inner wall of the contact stator and the elliptical cam, respectively, to reduce the impact of the blade on the rotor when they start or decrease the rotational speed. The opportunity has the function of protecting the blade and stabilizing the flow and pressure; the hollow rotor is placed between the inner wall of the stator and the elliptical cam, and the inner wall of the stator, the outer circumference of the rotor, the front cover and the blade form an outer air chamber, and the inner circle and the ellipse of the rotor The cam, the front cover and the vane form an internal air chamber, and the hollow rotor is designed to increase the utilization of the internal space of the stator and the volumetric flow rate of the gas. When the rotor rotates, the blade rotates and slides, and the volume change between the inner wall of the blade, the rotor, the stator and the elliptical cam and the front cover reaches the effect of compressing the gas, and is discharged through the valveless exhaust port of the stator. The gas inlet and exhaust ports are designed on the stator to save space in the outside of the inlet and outside the exhaust port and the overall compressor.
