Abstract

The present invention pertains to the field of power generation and transport means. The rotary engine includes a body with an inner bore, in which a rotor is mounted and comprises an insert that is concentrically arranged relative to the inner bore so as to define a gap, at least one shutter defining together with the insert a working chamber, a system for feeding a working medium and a system for discharging the processed working medium. The body includes at least one electromagnetic member capable of action on a corresponding shutter for enabling the free passage of the rotor insert and for closing in synchronization with the moments for feeding the working medium into the working chamber and for discharging the processed medium. The invention makes it possible to simplify the rotor structure, to control mobile shutters having various structures and to increase the performance index of the engine.

Description

 Rotary engine

 TECHNICAL AREA

 The invention relates to the field of energy and transport engineering, in particular to internal and external combustion engines of a working fluid or to drive motors using steam or compressed air as a working fluid.

 BACKGROUND

 A rotary engine is known that contains a housing with channels for supplying the working fluid and exhaust of the spent working fluid, in the bore of which there is a cylindrical rotor with a profiled protrusion that occupies half a quarter of the inner bore of the housing and smoothly passes into the main diameter of the rotor, a dividing flap that is constantly in contact with the rotor (see Patent RU 2116475 C 1, F02B53 / 00, published July 27, 1998).

 The closest analogue is a rotary engine containing a housing with a sleeve pressed into it, a cylindrical rotor mounted concentrically to the sleeve with a spring-loaded insert, radially movable, a dividing flap forming a working and non-working chamber with a spring-loaded insert, elements for supplying the working fluid and exhaust of the working fluid in addition, to mitigate the impact of the insert on the inner diameter of the case sleeve, a recess is made on it (see Patent RU 2229610 C2, 7F02B 53/00, published May 27, 2004).

A disadvantage of the known engines is the imperfection and complexity of the design of the rotor, the unreliability of the springs inserts and dampers in temperature conditions, as well as excessive wear of the separation damper when moving radially and when it contacts the insert, which leads to a decrease in KPD engine.

 SUMMARY OF THE INVENTION

 The objective of the invention is to simplify the design of the rotor, to increase KPD engine, eliminating springs, as well as reducing wear between the contacting elements and simplifying the repair of engine parts.

 The task is achieved due to the fact that the rotary engine contains a housing with a sleeve pressed into it or an internal cylindrical bore, a cylindrical rotor with an insert mounted concentrically to the internal bore or sleeve of the housing with a gap, at least one shutter, forming a working chamber with an insert, a feed system the working fluid with its internal or external supply and the exhaust system of the spent working fluid, while at least one electromagnetic element is placed in the housing with the possibility of w impact on the proper valve opening and its free passage for insertion of the rotor and close in concert with the time of filing the working fluid into the working chamber and discharge of spent working fluid.

 LIST OF DRAWINGS

The invention is illustrated by the drawing, the figure of which shows a cross section of a section of the proposed rotary engine. An example implementation of the invention

 The rotary engine section shown in the figure consists of a housing 1 with an internal cylindrical bore or with a sleeve 2 pressed into it and with cooling chambers 5 communicating with each other (not shown). The housing 1 has a cavity for placing an electromagnetic element 9 in it, affecting the operation of the dividing flap 12, which can have a different design, with pressure limiters on the surface 15 of the rotor 3 (not shown) and recesses 11 formed in the sleeve 2 for full placement in them shutters 12.

The electromagnetic element 9 is triggered (turned on and off) from the position sensors of the insert 6 (not shown), consistent with the moments of the supply of the working fluid to the working chamber 14 of combustion and the release of the spent working medium from the working chamber 14, which is formed between the dividing flap 12 when it is in contact with the outer surface 15 of the rotor 3 and one side of the fixed insert 6 fixed in the body of the rotor 3. The insert 6 is made with a bevel facing the direction of rotation of the rotor 3, its sharp end is located with a minimum clearance to the inside the front surface 16 of the sleeve 2 or the cylindrical bore of the housing 1. The working fluid in the combustion chamber 14 is fed through the working fluid supply system 10, while the combustion of the working fluid occurs from the spark plug 13 installed in the housing 1 between the shutter 12 and the spark plug insert 6. Exit of the spent working fluid from a non-working chamber 4 is carried out through the exhaust system 7 and is regulated by a shutter 8. If two or more sections mounted on one shaft are used in the work, their bodies with electromagnetic elements mounted in them and the rotors with inserts are offset by a certain angle relative to each other. As sealing elements between sections of a rotary engine, cylindrical rollers (not shown) can be used. Under certain conditions, the inoperative chamber 4 of the rotor cavity can operate as a working chamber. When the rotor 3 rotates, the dividing flap 12 slides along the outer surface 15 of the rotor 3, and when the insert 6 of the rotor 3 approaches, the electromagnetic element 9 is activated, and the flap 12 is removed into the recess 11 of the sleeve 2, while the insert 6 of the rotor 3 freely passes this section, and the flap 12 is released upon completion of the duty cycle. If the electromagnetic elements 9 fail, the shutter 12, due to its weight, comes into contact with the rotor 3 and is removed into the recess 11 by the insert 6 of the rotor 3.

 A rotary motor in combination with an electric generator and compressor can accumulate energy to control a multifunctional unit.

 The implementation of the invention in this way allows us to simplify the design of the rotor 3, to simplify the control of the movable shutter 12, which can be of various designs, and to increase KPD by reducing the friction of the contacting elements.
