Description

one

Rotary machines are known, for example, engines having a rotating cylinder with a curvilinear profile, a stator with segmental notches and rotary valves, which together with the cylinder and the stator form variable volume chambers. A disadvantage of the known machines is the presence of unbalanced rotating masses.

In order to balance the rotating masses in the proposed machine, the pistons, placed in the stator segment notches, have a double-sided profile formed by arcs of spirals, and the cylinder enclosing the stator is connected to the pistons by a gear train.

FIG. 1 shows the described machine, a longitudinal section along A-A in FIG. 2; in fig. 2 is a cross-section along pa of FIG. one

In the stator 1 in cylindrical chambers 2, having a segment shape with a segment boom larger than the radius, but smaller than the diameter of the chambers, 3 pistons 4 are rigidly mounted on the shafts. Gears 5 which is in engagement with the central tester

her rotor 6, the gear ratio of which is 1: 1. The rotor has an inlet O. and exhaust 5 windows. The outlet window is made in the form of a jet nozzle. The rotor is mounted in bearings 7 and 8. In the wall of the stator 1, spark plugs 9 are installed and a channel 6 is made for supplying the working mixture to the rotor inlet window.

The machine works as follows.

When the rotor 6 rotates, for example, clockwise, the pistons 4 receive a reverse rotation. In this case, alternating movement of the respective pistons along the inner surfaces of the rotor is provided with simultaneous alternating movement of the respective inner saddles of the rotor along the outer surfaces of the pistons. Variable-volume working chambers are formed between, between, the corresponding surfaces of the rotor, pistons and stator.

FIG. Figure 2 shows the moment when a suction stroke occurs in chamber B — the working mixture enters it through inlet port D., the working mixture is compressed in chamber D, expansion (working stroke) occurs in chamber D, and exhaust in chamber E. Thus, during one revolution of the rotor, four four-stroke cycles are carried out. that, in order to balance the rotating masses, the pistons located in the stator segment cut-outs have a double-sided profile formed by arcs of spirals, and the cylinder encircling the stator is associated with gear transmission. -one ue.f Y ////////////// J b
