Description

Impeller type rotary engine

The present invention is " impeller type rotary engine " further developed on the principle basis of " cylinder-piston rotary engine ", have more simple in structure, moving element is few, only with regard to cylinder body, piston, seal compression slide block and a bent roller, the assembling of external members such as the Carburetor of front and back cylinder cap and selected vehicle, spark plug, outlet pipe, clutch has just constituted complete rotary engine.

Below just the present invention contrast accompanying drawing and do concise and to the point the description: Fig. 1 be a plan view, and Fig. 2 is that the master looks accompanying drawing, and Fig. 3 is a schematic diagram.

Cylinder body 13 be the centre-to-centre spacing of two semicircles by the needs of volume, be linked to be level and smooth oval shape with circular arc. A semicircle encases piston 14, and the above space of another semicircle is compression chamber volume 16. Piston 14 by Three combustion chambers 15 and three road slide block slots 12 consist of support frames and are the impeller shape. It is hollow bulb between the framework Divide cheap circulation of air cooling. The middle part of framework is impeller shaft 7, and cylinder cap 27,5 before and after being packed in Bearing block 24 in. The centre bore of rotating shaft 7 is main oil gallery 25, and the fuel feed hole on interior with bearing block 24 6 and outage 26 communicate. When slide block 11 during at groove 12 interior stretching motion, lubricating oil is on bearing block Fuel feed hole 6 enters in main oil gallery 25 and the slide block slot 12, discharges and the formation circulation through outage 26 again then Oil circuit. When slide block is flexible in groove, when lubricating oil reaches the two cylinder cap side that contacts with slide block except lubricated slide block, Simultaneously again through the slide block oilhole 3 lubricated rollers 9 that are supported on the slide block. When roller with the slider roll Compressed Gas The time, lubricating oil lubricates again cylinder body inner orbit face 28 through roller 9 surfaces. Because the contact-making surface of roller and cylinder body Be the rolling friction sealing, fricative resistance is very little, therefore, and dry friction or without the sealing of lubricating oil not Can aggravate the wearing and tearing to cylinder body, only consider that the lubrication and seal in groove adopts the closed tolerance size as far as possible. Cause Slide block in groove and the outer end face seal of groove lubricated, mainly by the straight shape sealing strip 1 in the slide block two sides and It is friction sealed that the cylinder cap end face is made elasticity tension, scurries into inlet plenum to prevent Compressed Gas. Slide block sucks on one side Gas, on one side Compressed Gas, the roller 9 on the slide block top separates air inlet with calming the anger, therefore, and slide block Playing is lubricating oil pump, is again air-breathing double action of calming the anger. The slide block end face takes lubricating oil to work simultaneously Plug end face and sealing

ring

4,20 in the cannelure on the lube pistons end face are to prevent gas leak. Thereby Formation is arrived sealing ring 22, sealing strip with piston main oil gallery 25, bearing block 24, slide block oilhole 3, roller 9 1, until the sealing of the relevant moving component that cooperates with piston is with lubricated, thereby form the lubricated net of quad seal Network.

When piston 14 is done 360 ° of rotations around cylinder body 13, finish three air inlets, compression, workmanship, exhaust simultaneously.Slide block impels slide block to do the rolling linear sealing together with stretching on the roller with casing wall under the effect of centrifugal force and inertia oil pressure, can not seal creative than zone face owing to the line that does not have width contacts as cutting edge scraping casing wall.Also consider simultaneously to have designed the more reliable zone face seal lubrication scheme 10,17 of two covers, for its selection.Air inlet on one side, on one side compression, gas volume is changed, the selection of compression ratio and combustion chamber volume are complementary and determine the size that power is exported.In order to prevent leaking outside in the pressurized gas process,

annular groove

2,18 is arranged, on the both ends of the surface of cylinder body to be used as packing material, as asbestos product, sealing fat etc. belong to the sealing of static junction plane, play the medium effect of sealed against leakage when being connected with cylinder cap 5,27 as cylinder body 13.When slide block compression finishes when entering in the groove, spark plug is the indoor mixed gas of ignition combustion and expansion workmanship, and expanding gas is at this moment finished thermodynamic cycle along the expansion of expansion chamber 22 volumes and subsequently from relief opening 23 combustion gas.Because pressing chamber 16 and expansion chamber 22 apart separates, piston except that little part end face with cylinder cap contacts, remaining part is ventilation road junction 19, comprises the firing chamber base.The cooling of the lubricant oil in piston central oil passage and the slide block slot in addition, thus local superheating phenomenon in the thermal cycle process avoided.Because of the temperature distribution equilibrium around cylinder body, cylinder cap, the piston, chemical combination gas is not subjected to the influence of the strong waste heat in firing chamber, the yet corresponding increase of the explosive force that is associated with gas density again.

The present invention finishes a thermodynamic cycle and only need once promote moment of torsion similar in appearance to three cylinder four-journey Reciprocating engines.Removed water pump, oil pump in addition, power consumpiton that connecting rod piston and cam valve train brought also is better than conventional engines.Because suction port 8 is in relative position with relief opening 23, whole thermodynamic cycle is taken their own roads.Prolonged charging into of mixed gas in the restriction that is not subjected to air inlet system and exhaust system some more accordingly, also prolonged the process that drains waste gas simultaneously.Therefore, the generation of heat energy is substantially equal to change into the heat energy and the thermal loss lost with waste gas and that cooling is taken away of mechanical work.

The optimum working state of the associated components that designs by thermodynamic cycle is also uncomplicated.Owing to avoided the inertial force that non-uniform rotary motion produced and the restriction in stress and working life.Piston rotating shaft 7 of the present invention is packed in to be made isogonism speed in the cylinder cap bearing support 24 that links together with cylinder body and rotatablely moves, and the active force of two surface of contact of pretending relative movement is little.Do not have variable motion in the structure, owing to torsion, an axle winding degree evenly distribute, the beginning can obtain high rotational speed and performance.

The present invention presses the designing requirement of associated components, can make in the deviation range of maximum, neither influences its quality, does not also lose its necessary performance.As long as project organization is reasonable, selection is proper, can consider that cylinder body 13, cylinder cap 5,27, piston 14 adopt pottery to substitute cast iron.Because of the thermal expansion coefficient of pottery is little, stress and physical reactions are comparatively stable and wear-resisting, and processing and fabricating can be used bigger deviation, then do not have big influence to sealing and lubricating, and are that conventional engines is incomparable.Can be used as the problem of further investigation and make ceramic model machine.

Flame propagation adds what the speed of flame propagation was formed by the speed of mixed gas.Flame propagation mainly is on the mixed gas travel direction.The present invention adopts the dual ignition plug electronic ignition, also can with cylinder body that firing chamber 15 communicates on pressurized machine is installed or on expansion chamber 22 both ends of the surface, spark plug is installed, impel pressure to improve faster so as to quickening whole combustion process, make the inflation process of mixed gas that bigger space be arranged.Comparing Reciprocating engine has more leeway selecting aspect the spark-plug location, is enough to guarantee oil gas igniting more reliably in the ratio ranges of broad.

Plasticity of the present invention, the technological scheme that wide prospect is provided and has led for the utilization of modern new science and technology, new technology, new material.Each parts all has multi-functional purposes, and function that conventional engines had and characteristic have been contained in the combination of one-piece element, makes impeller type rotary engine motor commonly used have more stretchability, selectivity, applicability and development space.

From above description, the present invention has following major advantage:

1, simple in structure, cheap, no matter be volume and institute's consumption material of motor, add necessary manufacturing mechanism, all far below the cost of conventional engines.

2, good thermodynamic cycle might reach the highest thermal efficiency and greatly reduces toxic emission.
