Description

FIELD OF THE INVENTION The present invention relates to rotary internal combustion engines as a priority, as well as to steam engines, pumps and other variable-volume machines and equipment.

Known rotary engine, in which rotor pistons consisting of separate parallel pivot links are connected at their ends between a transverse and two side supports, one of which is provided with a piston control and power transmission groove on at least one side facing the end support end pivot. chained between themselves by joining the ends of the pivots and connected to the ends of the shaft crossing, and the piston control and powertrain grooves interact with at least two rollers cantileverally mounted on the sides of the housing (LR Patent No. 4665).

The disadvantage of the engine is that the piston pivotally mounted on the shaft cross-ends are closed-ended by their own links between the pivot joints and the exact pivoting angle of the pistons from the neutral position at 45 ° is difficult to achieve due to pivoting gaps and possible inaccuracies. the rotor, the smooth passage of the rollers from one piston to the adjacent control grooves and the difficulty of sealing the pivot joints.

Also, the masses of the pairs of transverse pivots that are closer to and closer to the cross-axis exhibit a difference in the centrifugal forces that rotate the shaft.

The range of volume differences for variable volume cameras is limited.

A machine is known with oscillating, cross-disposed, self-interacting piston pistons, wherein the oscillation of the pistons about their axes is performed by a groove and a power transmission roller (Patent No. PCT / US2007 / 079113).

The disadvantage of a machine with oscillating pistons is that the pistons interact with each other indirectly and through the links of motion transmission.

A known energy converting system that can work as a compressed gas or other media engine or as a pump (Patent No. PCT / HU 2009/000100).

The disadvantage of the energy conversion system is that the rotor moves in a non-circular chamber and this system requires controlled distribution valves.

Also known is a rotary internal combustion engine (patent No. BR P1-0704879-3) whose rotor rotates in a circular housing about its axis and orbits the center axis of the housing, and is controlled by a "Vankel" engine rotor control having three cylinder internal divisions, crankshaft plate with rotor spacers, with liners flanged perpendicular to the inner periphery surfaces of the housing.

The disadvantage of a rotary motor is that its compactness and weight are limited by the relatively large size of the rotor with its control mechanism and crankshaft, which requires balancing of its centrifugal forces

J weight and flywheel mass, because only one working cycle per crankshaft revolution, engine chamber is long for narrow combustion, difficult to cool working and opening hot plate plates, crankshaft with control mechanism required, plate design does not match on the other hand, the amount of engine main parts exceeds that of the Vankel engine and is about twenty-five details and fourteen of their names. For industrial use and as a convertible engine pump, its cylinder capacity can be utilized at only 50 percent.

Summary of the Invention This invention relates to the improvement of sealing of piston and rotor housing volume chambers, adjacent piston reciprocal interaction through niche overlap openings, reduction of centrifugal force rotations on rotor axle masses, accurate piston angular displacement of 45 ° from center position, enabling the range to the right, simplifying and simplifying the design as a whole, reducing the number of key details and achieving compactness, and expanding the scope for customization.

The specified technical result is obtained by placing a piston-carrying rotor with a pivot bearing rotor in its center, transverse recesses in its lateral recesses, with transverse fingers extending along the periphery of the rotor periphery with peripheral sealing elements extending therefrom, overlapping slots between adjacent niches, and moving the center of the roller controls on the piston grooves from the center of the housing to a diameter that touches the line passing between adjacent toe centers, and by installing two additional, -pump.

The rotary motor works this way.

Rotating the housing 1 with sides 2 in the center of the rotor 4 with its center axis 5 and on the fingers 8 transversely mounted on the periphery of the rotor with peripheral dividing and sealing elements 9 extending thereon in the laterally overlapping rotor recesses 6 by means of roller guides 13 mounted on the sides of the housing and between them by means of interacting mechanical elements 12, four alternating volume chambers 14, 15, 16, 17 arranged in a cross opposite to the inner periphery of the housing and sidewalls are formed rotor rotation takes place in four chamber volume change cycles, where during the first cycle the fuel mixture is sucked in through the first hole 3 in the rotor direction of rotation, which is compressed in the second cycle, burned in the third cycle and discharged in the fourth cycle while at the second rotor opening aperture 3.

The two additional openings 3 are located opposite the openings 3, enabling two rotary intake and exhaust cycles in one rotor rotation, which results in the engine becoming a double convertible rotary motor pump.

By changing the groove 11 in the grooves 11 of the pistons 10, the characteristic of the control of the pistons and the transmission of force to the rotor can be adjusted.

Comparison of the present invention with its analogs and prototype has enabled it to be determined to be a "novelty" of the crater. In other inventions in the field of technology, the identities that distinguish the proposed invention from the prototype have not been clarified, and therefore provide the invention with the criterion of "substantial differences ⁴ . Opportunities to radically change the contours of rotary internal combustion engines, radically simplifying and refining their compactness, improving their technology and increasing their efficiency.

The invention can be widely used in all variable displacement engines, pumps and other machines.
