Description

The invention relates to mechanical engineering and can be used to create rotary-vane engines, pumps, compressors.

A rotary-blade machine design is known, comprising a housing with inlet and outlet nozzles, a rotor end caps and a rotor alternate rotation mechanism ozazhranenny the outside of the end cap consisting of a rotor with blades, coaxially mounted with the possibility of alternate rotation, placed between the rotors of the mechanism of alternate rotation of the flywheel and the locks of the rotors, made in the form of rollers, placed respectively in the grooves of the housing and the flywheel and through holes of the rotor blades mechanism alternating rotation, whereby the depth of the recesses is less than the radius of the rollers.

However, in this design, the mechanism for transferring the rollers from the housing to the flywheel is not effective, since it does not exclude jamming of the rollers between the housing and the flywheel.

FIG. 1 shows a rotor-blade machine with a mechanism for alternately rotating rotors outside the cylindrical casing of this machine, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 - alternate mechanism

rotation in the casing, located outside, isometric; in fig. 6 shows the geometry of the blades of the alternating rotation mechanism, recesses, and rollers.

The rotor-blade machine includes a housing 1 with inlet pipes 2 and a working medium outlet 3, end caps 4 and 5, rotors b and 7, a mechanism for rotating rotors alternately, which is placed outside the end cap 4 and includes a housing 8, rotors 9 and 10 with blades installed with the possibility of alternate rotation, a flywheel 11 is placed between the rotors. In the recesses 12 of the casing and 13 of the flywheel and through holes of the blades of the rotors 14 and 15, there are rotors of clips made in the form of rollers 16 and 17.

Rotary-blade machine works as follows.

The flywheel 11 rotates clockwise evenly. The rotor 10 of the mechanism of alternate rotation is connected by rollers 17 with the fixed casing 8 of this mechanism, and the rotor 9 of the mechanism of alternate rotation is connected by rollers 16 with a flywheel 11, and the rotors 6 and 7 of the rotary-blade machine make the same movements as they are shafts (not shown ) are connected with rotors of alternate rotation and repeat their movement. Through pipe 2 is the absorption of the working mixture. The rotor 9, continuing to rotate clockwise with the flywheel 11, acts on the rotor 10, while the arcuate recesses 12 in the housing and the recesses 13 in the flywheel accommodate each other. There are no obstacles to the movement of the rollers 17 from the casing 8 to the recess 13 of the flywheel and the rollers 16 of the flywheel in the recesses 12 of the casing. The rollers 16 and 17 begin simultaneous movement, the transition from the flywheel to the casing and from the casing to the flywheel.

This movement is carried out due to the buoyancy force, since the radius of the roller is greater than the depth of the recesses.

The roller 16, coming out of the notch of the flywheel at 1/2 of the depth, enters the casing 12. In this position, the geometry of the lengths of the casing and flywheel is taken. The roller 16, continuing further movement into the recess 12 of the casing, acts through the walls of the blades on the roller 17, forcing it to plunge further into the recess of the flywheel, since the length of the notch of the burner prevents the rollers 16 and 17 from being at the same time. When this roller 17, the transition into the niche 13 of the flywheel, pushes the roller 16 into the niche 12 of the casing, as

The niche length 13 of the flywheel is not available to the two rollers 16 and 17 because of the limited length. With the final transition of the roller 16 of the rotor 9 to the flywheel, and roller 17

the flywheel 11 to the casing 8, the rotor 9, connected to the casing 8, stops, and the rotor 10, connecting to the flywheel 11, also stays for a moment until the flywheel rotates the length of the notch of the roller 17, notch. This idle flywheel. Another edge of the notch of the flywheel (Fig. 6, t. B), approaching the roller 17, begins to turn the roller 17 together with the rotor 10. The rotor 10

moving with the handwheel in a clockwise direction. The rotor 10 approaches the rotor 9, acts on it, a simultaneous transition of the latching rollers begins, and everything repeats. Thus, the rotors perform alternate rotation, making the suction, compression, expansion and exhaust of the working fluid.

A feature of the proposed engine is that it has four

chambers in which work cycles are carried out.
