Description

The utility model relates to mechanical engineering, namely to the field of engine building, and can find application in the design and manufacture of internal combustion engines.

Closest to the claimed utility model (prototype) is the well-known rotor-vane engine according to patent RU 2298651 C1, author and applicant Krajushkin G.P., published on May 10, 2007, bull. No. 13, comprising a housing having radial partitions installed in the housing with the possibility of rotation around its axis, a rotor with radial blades interacting with the inner annular surface of the housing and with radial partitions, as well as seals for sealing the contact areas of the rotor blades with the inner annular surface of the body sa. In this case, the radial partitions are made in the form of retractable flaps installed in the grooves of the cylinder and the engine body, while the internal volume of the cylinder is divided by the flaps into two working zones: air, consisting of suction and compression cavities of air and fuel, consisting of working and exhaust cavities, moreover, each of these cavities is equipped with an inlet (outlet) window, and the working cavity is connected through the said window to the combustion chamber, while the engine is additionally equipped with a spray and ignition system I of the fuel mixture, a system for supplying high pressure of working gas to the valves, a system for purging exhaust gases from the combustion chamber after the working stroke, a system for sealing the end walls of the blades with the end walls of the cylinder in the contact zone to compensate for the wear of these walls.

The disadvantages of the known engine are the system of atomization and ignition of the fuel mixture, which contains two bypass valves, an air nozzle, a fuel nozzle and a high pressure pump consisting of one pump, which will not be enough to raise the high air pressure to the desired compression ratio, and therefore the air supplied through the nozzle in the combustion chamber, the air stream will be at insufficient temperature to ignite the fuel mixture, which will lead to unstable engine operation. A system for supplying high pressure of working gas to valves, including a hole on the end wall of the cylinder, a pipeline, a synchronizing rod with a groove for relieving high pressure after moving the blades by more than 90 °, which is kinematically connected to the cam on the driven gear of the chain gear, pump for separating the working gases from the air, connected by a pipeline with cavities located above the protrusions on the tops of the valves. During operation, the hole on the end wall of the cylinder, the stem with the groove, and the pipe connecting it to the pump will be coked by the exhaust gases of the working stroke and clog them, which will reduce the engine's service life. A sealing device is not provided between the ends of the flaps with the surface of the blades at the place where the flaps slide along the blades.

The objective of the utility model is to eliminate these drawbacks by increasing the life of the engine due to the use of high pressure pumps, the working fluid of which is the air they suck in, in the system for supplying high pressure to the valves, thereby avoiding the use of working gases from the combustion chamber, and reliability in operation engine due to increased air pressure in the ignition system of the fuel mixture in the combustion chamber and due to the use of sealing at the contact between the valves and the blades.

The problem is solved in the proposed rotary vane engine, comprising a housing having radial partitions mounted in the housing with the possibility of rotation around its axis of the rotor with radial blades interacting with the inner annular surface of the housing and with radial partitions, as well as seals for sealing the contact areas of the blades a rotor with an inner annular surface of the housing, wherein said seals are made in the form of plates placed in grooves on the tops of the blades, and a counterweight Connected to said plate via the gear shaft mounted between them in the blades.

Thus, the air stream supplied through the air nozzle to the combustion chamber with a high temperature and high pressure is directed to the fuel jet sprayed by the fuel nozzle with the formation of a highly dispersed self-igniting fuel mixture. The system for supplying high pressure to the valves during the blades moving away from the valves to an angle of up to 90 ° at a high rotor speed contains a high-pressure pump consisting of three pumps with four needle valves connected by a pipeline in the engine body to the cavities located on the tops of the valves near the protrusions on sashes and limited by the body of the engine.

The rotary vane engine consists of a rotor including a rotor shaft 52 with rotor blades 51 and 53 (FIG. 1, 2, 3), the housing 12 is cylindrical in shape (FIG. 1, 7), closed from the end sides by the end walls 54, 55 (Fig. 6, 8) attached to the housing 12 by bolts 70 (FIG. 6, 8, 10,).  Bolts 70 pass through holes 56 (FIG. 7) in the end walls 54, 55 and in the bearing housings 57 (Fig. 10).  The entire length of the housing 12 has two radially sliding partitions in the form of wings 7, 24 (Fig. 1, 7) passing through window 67 (Fig. 6) in the housing 12.  The flaps 7, 24 divide the volume of the housing 12 into two equal parts, i.e. to.  they abut against the rotor blades 51, 53, which sit on the rotor shaft 52 (FIG. 13).  The shutters 7 and 24 are pressed by the springs 1 and 27 to the blades to create a place for sealing the blades with the shutters.  Springs 1 and 27 are installed in sockets that are pressed by covers 79 screwed to the engine housing.  The blades 51, 53 with their vertices touch the inner cylindrical surface of the housing and, passing the flaps during rotation of the shaft clockwise, form cavities 19, 11, 37, 41, Fig 1 which, in turn, form two working zones: air and fuel.  The cavities 11 and 19 form the air zone, and the cavities 37, 41 form the fuel zone.  These zones are separated from each other by wings 7 and 24.  On the sides of the housing 12 near the windows 67 on both sides there are inlet (outlet) windows 20, 10, 35, 21 (Fig. 16).  Into the cavity 19 through the window 20 and the suction pipe 22, air is sucked in - the suction cavity.  From the cavity 11 - the compression cavity - the compressed air is forced out through the window 10 and the bypass valve 8 into the atomization and ignition system of the fuel mixture.  The fuel mixture atomization and ignition system includes a high pressure pump consisting of three pumps 28, 29, 30, an air nozzle 31, and a fuel nozzle 33 located in the engine body (FIG. 1, 7, 8).  The window 10 through the bypass valve 8 is connected by a pipe 3 to a high pressure pump, which is connected to an air nozzle 31 (Fig. one).  An air nozzle, an overflow valve 34, and a fuel nozzle 33 are connected to the combustion chamber 9.  From the fuel nozzle, the fuel is sprayed, and a hot stream of compressed air is sent to the sprayed jet, which makes the sprayed jet “bombarded” with this air and mixes well with it, forming a highly dispersed fuel mixture, and ignites.  The pre-chamber 9 of the combustion of the fuel mixture exits through the window 35 in the housing 12 into the cavity 37 (Fig. 1, 7,) of the stroke.  The pistons of the high pressure pumps are driven by a chain drive with a gear ratio of 1/2.  Chain drive gear 49 (FIG. 1, 12) sits rigidly on the shaft 52.  On the driven gear 47 there is an eccentric 48, with which the piston rods of the pumps 28, 29, 30 are connected to the high pressure pump via a rod and rocker.  From the combustion chamber 9 (FIG. 1, 7,) expanding gases through the window 35 enter the cavity 37 - the cavity of the working stroke.  From the exhaust cavity 41 through the window 21 (FIG. 1, 7) and the exhaust pipe 23, the exhaust gases are forced out by the blades.  The rotor shaft 52 with blades 51, 53 have an internal cavity 14 (FIG. 2, 3, 4) for oil cooling of the rotor.  Cooling oil is supplied to the pipe 62 (FIG. 10) through the oil channel 69 for cooling the rotor, the hole 63 on the rotor shaft, through the cavity 14 of the rotor shaft 52 and the blades 51, 53, and is discharged through the same pipe 62 at the other end of the shaft.  The device for increasing the service life of the sealing plates in the contact zone of the tops of the blades with the inner surface of the cylinder contains a groove 16 made on each top of the blade (Fig. 2, 3) into which a sealing plate 18 with a curved spring plate 17 is inserted to seal the contact point of the tops of the blades 51, 53 with the inner surface of the housing 12 and the counterweight 75 in the groove 87 (FIG. 2, 3), and between them a gear rod 50 is installed, which connects the sealing plate 18 with the counterweight 75 with teeth.  This device is designed to eliminate the action of centrifugal force that occurs when the rotor rotates, causing accelerated wear of the plate 18 from the action of centrifugal force.  To ensure the tightness of the contact points of the end surfaces of the blades with the end surfaces of the cylinder walls in the zone of their contact and to compensate for the wear of these end surfaces, the engine is equipped with a sealing system, which includes a continuous transverse cross-sectional view of the rotor 64 with blades, springs 60 (Fig. 10), working on the separation of the rotor parts in the section and pressing the end walls of the blades to the end walls of the cylinder, with the springs 60 mounted on the shaft 52 of the rotor between the housing of the oil channels 62, rigidly mounted on the engine housing, and gears 49 and 59, rigidly sitting on the rotor shaft.  The parts of the rotor with blades in the place of the cut 64 have a connection made in the form of a spline, and along the perimeter of the blades in the form of a “skirt” 66 (Fig. 3, 4) so as not to let compressed gases pass through the connection, and for strong adhesion of the rotor parts to each other on one half of the shaft, there are two rectangular protrusions 65 inserted into the reciprocal grooves on the other half of the shaft.  Section 64 is necessary for tightly pressing the end walls of the blades and the inner end walls 54, 55 of the housing 12.  On both sides of the shaft 52, springs 60 are installed (Fig. 10), which create efforts aimed at spreading the rotor with the blades in place of the cut 64 for tightly pressing the end walls of the blades to the end walls of the housing and sealing their contact points.  The system for supplying high pressure to the leaves 7, 24 for tightly pressing them against the blades 51, 53 during the departure of the blades from the leaves to 90 ° includes 3 pumps 32, 36, 44 and 4 needle valves 84, 85, 86, 87 (Fig. 1, 7) connected by a pipe 43 with cavities 6, 26 located above the protrusions 46 (Figs. 1, 7) on the upper part of the valves.  The pistons of the pumps are driven by a chain gear with a gear ratio 1/2, the drive gear 49 of the transmission sits rigidly on the shaft 52.  On the driven gear 47 there is an eccentric 48, to which a rod is connected, which drives the beam 15 (Fig. 1, 12), to which the pistons of the pumps 32, 36, 44 are connected.  In the grooves between the tops of the valves and the engine body near the protrusions 46, cavities 6, 26 and 5, 25 are formed on the valves, which vary in volume depending on the reciprocating movement of the valves, sliding their ends along the rotor blades 51, 53 (Fig. 1).  The cavities 5, 25 are located symmetrically to the cavities 6, 26 and are isolated from them.  The cavity 5 is connected to the cavity 25 by a pipe 4 (FIG. 1, 5, 8), the cavity 6 is connected to the cavity 26 by a pipe 43.  Air to fill the increasing volumes of the cavities 5, 25 during the movement of the valves 7, 24 into the cylinder body enters through the bypass valve 2 and the pipe 4 (Fig. 19).  The exhaust gas purge system from the combustion chamber after the stroke includes cavities 5, 25, a bypass valve 34 connected to the fuel mixture combustion chamber 9, and a bypass valve 2 (FIG. 1).  The combustion chamber is purged with compressed air supplied through the pipe 4 from the cavities 5, 25 when the wings 7, 24 move during their displacement by the vanes 51, 53 from the housing, through the bypass valve 34 into the combustion chamber 9 at the moment when the vanes pass through the valves.  The flaps installed in the grooves of the engine body on the side walls at the end of the flaps have a sealing device that holds air in the cavities located near the protrusions on the top of the flaps and contains a groove 73 of FIG. 16 in which a seal plate with a bent spring plate 71 of FIG. 17 to press the seal plate against the end wall of the groove.  To spray fuel in the combustion chamber, fuel is supplied from the fuel equipment (not shown in the drawings) through the fuel injector 33 (FIG. 1, 7).  On both sides of the shaft 52, bearings 57 with bearings 61 are installed (FIG. 10).  Bearings 57 are attached to the end walls 54, 55 of the housing 12.  Water for cooling the housing is supplied to the pipe 58 and, having passed the engine cavity, is discharged through the pipe 68 (Fig. 7).  Oil for lubricating the rods of high pressure pumps 28, 29, 30, 32, 36, 44, valves 8, 34 and the air nozzle 31 is poured through the pipe 83 in the upper engine cover 79 (FIG. 7).  The bypass valve 8 opens when the pressure of the compressible air in the cavity 11 of the housing 12 exceeds the spring tension of the bypass valve and this pressure is supplied from the end of the valve.  The bypass valve 34 is similarly configured, but the pressure for opening the valve is supplied to the side of the valve (FIG. 1, 8, 9).  Air nozzle 31 (FIG. 8) opens when the air pressure for opening is supplied from the side and exceeds the tension of its spring, and, having passed the nozzle, leaves its end.  Adjustment of the spring tension to open the air nozzle is made by the manufacturer.  To regulate the spring tension of the air nozzle 31, there are nuts 73, 74 which are screwed onto the stem of the air nozzle (FIG. eleven).  To seal the flaps 7, 24 with the walls of the engine grooves along which the flaps move, there are grooves 72 in the engine body and in the flaps 7, 24 (Fig. 7) into which spring-loaded seal plates are inserted.  The proposed rotary vane engine operates as follows.  When the rotor blades 51, 53 rotate on the shaft 52 in the housing 12 for half their revolution, suction, compression, stroke and exhaust are simultaneously performed.  For the other half of the shaft revolution, the cycle is repeated and this is achieved by the fact that the volume of the cylindrical body 12 is divided into two working zones: air and fuel, formed by two wings 7, 24, moving radially, sliding along the surfaces of the blades 51, 53.  When the blades move from one leaf to another in a clockwise direction, cavities are formed in the housing 12.  The suction cavity 19, starting from zero, increases to the maximum value - half the volume of the cylinder, there is air intake through the window 20 in the housing 12.  The cavity 11, respectively, decreases to zero, there is air compression, which is forced out of the cavity through the window 10 of the housing 12 into the pre-chamber 9 through the bypass valve 8, the high pressure pump 28, 29 30 increases the pressure even more and through the nozzle 31 the air enters the pre-chamber 9 combustion.  These valves 8, pump 28, 29.30, the nozzle 31 together with the fuel nozzle 33 are included in the system of atomization and ignition of the fuel mixture.  The cavity 37 of the working stroke increases when the blades turn from zero to the maximum value - half the volume of the entire cylinder, there is a working stroke, i.e. to.  through the window 35 from the combustion chamber 9, expanding gases enter the cavity 37, press on the blade 51 and rotate the shaft.  The cavity 41 is accordingly reduced to zero, there is an exhaust exhaust through the window 21 in the housing 12.  The movement of the pistons of the high-pressure pump downward starts at the moment when the blades 7, 24 do not reach the valves by 20 ° -10 °, this is achieved by rearranging the teeth of gear 47 with the installation of the eccentric 48 at top dead center.  The pistons of the high pressure pumps 28, 29, 30 will make a downward movement and rise upward over half a revolution of the shaft 52.  Compressed air from the cavity 11 is displaced through the window 10 and enters through the bypass valve 8 through the pipeline 3 into the upper increasing cavity of the pumps 28, 29, 30 through the needle valve 40 until the longitudinal axis of the blades is 90 ° with the longitudinal axis of the valves.  When the pistons of the pumps 28, 29, 30 move downward, the compressed air is displaced from the lower cavities, since the valve 38 is closed, air from the lower cavities enters the air nozzle, which, having overcome the tension of the springs, will open its valve and the highly compressed air will enter the heated combustion chamber 9 by a jet until the pistons of the pumps reach the bottom dead center and squeeze out all the compressible air.  The movement of the pistons starts up to 180 °, during which time filling with compressed air from the compression chamber of the working cylinder 11 into the lower cavities of the pumps 28, 29 through the needle valve 45 will begin, and since the compressed air in the upper cavities of the pumps will open valve 38 and close valve 39 air will enter the lower cavity of the pump 30, where the pressure will increase.  Next, the cycle repeats.  The air nozzle 31 opens at the moment when the blade has just closed the window 35 of the housing 12.  To do this, the piston of the pump 29 should begin to move downward at the moment when the blades 51 do not reach the leaf 7 by 20 ° -10 ° to create pressure in the lower cavities of the high pressure pumps 28, 29, 30 to open the valve of the air nozzle 31, and beyond this time, the blade 51 reaches the sash and closes the window 35.  The moment of opening the valve of the air nozzle 31 is achieved by rearranging the teeth of the gear 47 of the chain drive and changing the spring tension of the air nozzle.  To do this, you need to install the shaft, without reaching the blade 51 to the leaf 7 by 20 ° -10 °, the eccentric 48 of the gear 47 of the chain gear must be installed at the top dead point by rearranging the teeth in the chain gear.  Unscrew fuel injector 33 and screw manometer instead.  To weaken the spring tension of the air nozzle 31 by turning the nut 74 a few turns, and by rotating the rotor shaft, to achieve the highest impulse value of high pressure in the combustion chamber 9 by screwing the nut 74 on the rod of the air nozzle 31.  Lock nut 74 with nut 73.  When the blade 51 or 53 after closing the window 35 rotates another 3 ° -5 °, fuel is supplied through the fuel nozzle 33 in the combustion chamber 9.  Fuel is sprayed by the fuel nozzle 33 and getting under a stream of highly compressed, high-temperature air from the air nozzle 31, is “bombarded”, sprayed even more, forming a highly dispersed self-igniting fuel mixture, which leads to self-ignition of the fuel mixture.  The resulting fuel mixture burns.  The burning time of the mixture increases, t. to.  still continues the flow of compressed air, so the fuel burns completely in the combustion chamber 9.  The expanding working gases enter the working cavity 37 and press on the blade, providing rotation of the rotor.  The blade 51, reaching the wing 24, will open the window 21.  The pressure in the cavity 37 is released.  The high pressure will also be relieved in the combustion chamber 9, i.e. to.  the window 21 of the housing 12 is wider than other windows 10, 20, 35 of the housing.  The tops of the blades 51, 53, being on the line of the wings 7, 24, will not overlap the windows 21, 35 at the same time, at this time high pressure is also released in the combustion chamber 9.  This creates the conditions for the operation of the exhaust gas purge system from the combustion chamber.  When depressurizing the pre-chamber 9, a condition is created for opening the valve 34, t. to.  the flaps 7, 24, being in the extruded position, the ends of the compressed air in the cavities 5, 25, is displaced and through the pipe 4 through the opening valve 34 enters the combustion chamber 9 to purge the exhaust gases from the chamber.  The other blade, which has passed through the shutter 7, will begin to push the exhaust gases out of the cavity 41 through the window 21 and the exhaust pipe 23 on one side of the blade, and on the other side of the blade, the next stroke will also begin.  At a high rotational speed of the rotor blades, the shutters 7, 24 can be “knocked out” by inertia or lagging behind the blades when the blades move away from the shutters and this will disrupt the operation of the engine due to the transition of gases from one cylinder cavity to another.  To prevent this from happening, a high pressure system is provided for the tops of the wings to ensure a tight hold of the wings against the blades.  At the moment when the blades reaching the flaps with their peaks displaced the flaps from the cylinder and as the blades rotate, the flaps will enter the inside of the cylinder under the pressure of the high-pressure pump, which will be supplied to the flaps until the blades move away from the flaps by 90 °, Movement the pistons of the high-pressure pump upward starts at the moment when the blades do not reach the leaflets by 20 ° -10 °, to create sufficient pressure so that the leaflets can be strongly pressed against them when the blades move away.  The air in the upper cavities of the pumps 44, 36, 32 will begin to be compressed by the pistons moving upward and will begin to be displaced in the cavity 6, 26.  When compressed air enters the cavity, pressure will begin on the protrusions of the flaps, which will press the flaps against the blades and begin to move inward into the cylinder as the blades move away from the flaps.  The lower cavities of the pumps will be filled with air through a needle valve 85.  Since the switching needle valve 13 is closed, air from the upper cavities enters through the open passage of the valve 13 into the cavity of the leaves 6, 26.  After changing the direction of movement, the pistons will start to move downward, valve 85 will close, valve 13 will open and block the valve connecting the upper pump cavities to the cavities on the valves; therefore, the air displaced from the lower pump cavities will enter the upper pump cavity 44, since the valve 86 is closed.  The pressure in the upper cavity of the pump will increase significantly.  After changing the direction of movement of the pistons of the pumps upward, air from the upper cavity of the pump 44 will begin to flow through the switching needle valve 13, in the cavity of the valves, since the movement of air from the lower cavities of the pumps is stopped from changing the direction of movement of the pistons, so the valve 13 switched.  Also, the injected air through the valve 84 in the upper cavities of the pumps 32, 36 will be displaced in the cavity of the valves, since the valve 84 will close and the air will enter through the valve 86, as a result of which the air entering the valves will be of very high pressure, which will be sufficient so that the leaves have time to press against the blades that are removed from the leaves with a high rotation speed.  The pistons of the pumps are driven from a chain gear with a gear ratio 1/2 from the drive gear 49 of the gear, which sits rigidly on the shaft 52.  On the driven gear there is an eccentric 48, to which a rod is connected to drive the rocker 15 into motion, to which the pistons of the pumps 44, 36, 32 are connected.  Entering the valves into the cylinder, the nozzle 92 is opened by the protrusions on the valves and the pressure in the cavities 6, 26 is relieved and the pressure on the valves is relieved.  Since the flaps will begin to be forced out by the blades from the cylinder, air pressure on them is not necessary.  Compressed air in the cavities 5, 25 with the ends of the valves, for purging the combustion chamber, will exit the cavities 5, 25 through the valve 34 only when the valves and blades are on the same axial line and when the pressure in the working cavity is relieved.  A device for increasing the service life of seal plates 18 installed in the contact zone of the tops of the blades with the inner surface of the cylinder 12 to seal the contact point and eliminate wear of the plates from friction arising from the action of centrifugal force and contains seal plates 18 mounted in the grooves 16 located on the blades while the plates 18 are spring-loaded with curved plates 17 to the inner surface of the cylinder, a counterweight 75 is installed parallel to them in the grooves 87, the weight of which is equal to the weight of the plates 18 from the plates 17, and between them a gear rod 50 is installed in the form of a gear wheel on an axis 76, which is inserted into the drilled recesses of the blade.  The teeth of the stem engage with the teeth of the plate and counterweight.  With an increase in the number of engine revolutions, a centrifugal force acts on the plates, which, with an increase in the number of engine revolutions, will strongly increase and press the plates against the inner surface of the cylinder, which increases the friction of the seal plates 18 with the inner surface of the cylinder.  This means that the wear of the plates at the point of contact increases, therefore, a counterweight is provided that removes the action of centrifugal force, pressing the plates to the inner surface of the cylinder at any speed of rotation of the blades, and pressing the plates 18 to the inner surface of the cylinder will provide flexible plates 17 that will press with constant force that will ensure a long service life of the plates 18 of the seal in place of sealing.  When the blade rotates, the sash slides along its surface at a different angle of “attack”, therefore, the area of contact of the surface of the blade with the end face of the sash changes, as a result of which the sealing at the point of contact can be broken, therefore, at the end of the sash at the point of contact with the blade there is a rotary roller 80 of Fig. , 15 to which a sliding plate 81 is attached, which will maintain a constant contact across the area of contact.  The installed roller, turning in a semicircular groove, will slide with the sliding plate along the blade surface over the entire area of the plate.  In order to prevent the roller from falling out of the groove, it is attached to the casement by a bracket 82, which is inserted at its ends into the drilled recesses 93 of FIG. 15, which will hold the roller in the groove.
