Problems solved by technology

First of all, due to the combined motion structure composed of the rotating crankshaft, the swinging connecting rod, and the linearly reciprocating piston, the mechanical balance of this variable volume device is poor during operation, and most of the friction surfaces are unevenly worn, which affects the service life.
Secondly, in order to ensure sufficient mechanical strength, the weight and volume per unit displacement of the variable volume device are relatively large
When using this variable cavity volume device as an internal combustion engine: the crankshaft with the traditional four-stroke structure does work only once every two revolutions, the specific power is the smallest, and a complex valve control device is required
The crankshaft of a two-stroke engine does work once every revolution. Theoretically, the specific power should be twice as high as that of the four-stroke structure. Direct discharge without burning causes waste
This technical solution utilizes the grooves on the proximal side of the left and right blades, so that the left and right blades are fastened together through the grooves and put on the engine shaft to form four chambers in cooperation with the annular turning space in the casing, which are connected with the front Compared with the technical solution, the strength of the left and right blades is improved, but compared with the previous technical solution, the weight of the left and right blades of this structure is large, and the number of components in the cylindrical gear-elliptical gear transmission mechanism is large, which increases the specific mass

Abstract

The invention provides a blade-type cavity volume variation device, a blade-type internal-combustion engine and a blade-type compressor, which relates to a device that makes turning movement of piston in a cylinder body and an internal-combustion engine and a compressor with such a device. In the device, two groups of pistons positioned in misalignment on same axle of the cylinder body divide the turning space into four independent working cavities; the rotor axles for the two groups of pistons respectively fix an oval gear wheel, which engages with an oval gear wheel fixed on a transmission axle; the two groups of piston have same rectangular blade; a circular flange is provided at the lower section of a first group of piston; the lower half on the internal end face of two blades in the first group of piston is positioned on the external circumferential surface of the flange; the rotor axle for a second group of piston is configured as a sleeve that is bushed to the rotor axle of the first group of piston; the upper half on the internal end face for two blades in the second group of piston is positioned at the bottom of the external circumferential surface of the sleeve; the bottom end face of the sleeve adheres to the upper surface of the circular flange in the first group of piston. Therefore, the invention has the advantages of high intensity and light weight of blades.
