Abstract

A valve compression type rotary engine belongs to the gasoline internal combustion engine field, which comprises a combustion chamber, a spark plug, a valve, a valve spring, a shell, a rotor, a carburetor, a power taking off shaft and an exhaust pipe. A mixed gas cavity is formed between the shell of the inner cavity and the surface of the rotor, the mixed gas is compressed into the combustion chamber by the valve, then ignited by the spark plug to explode, then the rotor is pushed to work to output the power. The engine solves a plurality of problems, such as the modern rotary engine with complex structure because of using the three lobe rotor, high cost, difficult sealing, low reliability, difficult popularization and use. And the engine has advantages of good combustibility, smooth running, large power, simple structure and low cost.

Description

Valve compression type rotary engine

The utility model relates to a kind of rotary engine, particularly a kind of valve compression type rotary engine.

At present, general motor generally all is two kinds of forms, that is: double-acting cylinder motor and rotary engine.For reciprocating type cylinder engine, its shortcoming is the reciprocal inertia force that exists connecting rod, piston set, easily causes the overload of vibration and crankshaft-link rod piston set, have a strong impact on the raising of engine speed, and because frictional resistance is big, negative work consumption is many, causes engine efficiency low.In addition, the four stroke engine complex structure, cost is higher.Though the two stroke engine structure has had simplification, its usage economy is poor, and exhaust emission pollution is big.Rotor motor is the significant improvement at the said structure motor, and rotor motor generally all is to adopt triangle piston as rotor, but the point effect of triangle piston, the judder that non-pure rotation causes.Existing rotary engine sealing and lubrication problem all are difficult to solve, and influence the reliability of performance, influence applying of rotary engine.In addition, rotor motor is by rotor ring the housing inner chamber to be divided into compression cylinder and expansion cylinder when adopting triangle piston to make rotor, there is not definite firing chamber, the blast back is limited to the thrust of rotor, makes that the acting of rotary engine is less, and makes the power of its motor little.

The purpose of this utility model is, provides a kind of and has good burning performance, and the running balance, power is big, and is simple in structure, good seal performance, the valve compression type rotary engine of low cost of manufacture.

The utility model is to adopt following technological scheme to realize above-mentioned purpose.

This valve compression type rotary engine, by firing chamber 1, spark plug 2, valve 3, valve spring 4, shell 7, rotor 9, Carburetor 11, pto 12, outlet pipe 13 is formed, outlet pipe 13 is housed on the shell 7, Carburetor 11 and spark plug 2, rotor 9 is contained in the inner chamber of shell 7 by output shaft 12, it is characterized in that: the inner chamber of shell 7 is a cylindroid shape, rotor 9 is the garden cylindricality, be formed with a mixed gas body cavity 8 between the outer surface of the inner chamber of shell 7 and rotor 9, valve 3 is housed on the rotor 9, one valve spring 4 is housed below the valve 3, be shaped on a machine oil chamber 5 below the valve spring 4, have Oil passage 10 between machine oil chamber 5 and the pto 12, be shaped on a firing chamber 1 on the post surface, garden of rotor 9, and be with rotor ring 6.

When rotor 9 rotates, by the fuel-air mixture body in the valve 3 compressed mixed gas chambeies 8, make mixed gas enter firing chamber 1, when firing chamber 1 goes to the igniting of spark plug 2 places, make the mixed gas in the firing chamber 1 produce blast, rotate and promote rotor 9, get final product outputting power by pto 12.

The utility model has the advantages that mixed gas body cavity and compression chamber are separated by valve, in pressurized gas, enter mixed gas, the firing chamber is arranged on the rotor, make the pressurized gas physical efficiency all enter the firing chamber and burn, improved the efficient of acting widely, igniting accurately rapidly.The machine oil chamber is arranged on below the valve, valve is provided with machine oil groove and seal ring, even without special oil pump, utilize the radially activity of valve also can make movable parts such as valve, rotor and pto obtain well lubricating, and it is simple in structure, manufacturing price is cheap, and is easy to maintenance, is easy to promote the use of.

Below in conjunction with accompanying drawing the utility model is done to describe further.

Accompanying drawing 1 is a valve compression type rotary engine axial section structural representation;

Accompanying drawing 2 is a valve compression type rotary engine radial section structural representation;

Accompanying drawing 3 begins the compressed mixed gas structural representation for valve;

Accompanying drawing 4 is for compressed mixed gas and enter the mixed gas structural representation simultaneously;

Accompanying drawing 5 is a plug ignition status architecture schematic representation;

Accompanying drawing 6 is the exhaust condition structural representation.

This valve compression type rotary engine is to be that cylindroid shell 7 and a garden post rotor 9 constitute by an inner chamber, spark plug 2, outlet pipe 13 and the Carburetor 11 of igniting usefulness are housed on the shell 7, shell 7 is connected by pto 12 with rotor 9, is formed with a mixed gas body cavity 8 between the post surface, outer garden of the inner chamber of shell 7 and rotor 9.Rotor 9 surfaces are shaped on the firing chamber 1 that a shape resembles sub warhead, and valve 3 is housed in the rotor 9, are promoted by valve spring 4.One machine oil chamber 5 is arranged below the valve spring 4, and the machine oil in the machine oil chamber 5 by Oil passage 10 lubricated ptos 12, lubricates valve 3 because of action of centrifugal force on the one hand on the other hand, and by the lubricated rotor ring 6 of the oil duct on the valve 3.During startup, by starting electrical machinery rotor 9 is rotated, valve 3 is protruding under the effect of valve spring 4, make its internal chamber wall of being close to shell 7, when valve 3 forwards the ingress of Carburetor 11 to, the mixed gas in the valve 3 beginning compressed mixed gas chambeies 8, simultaneously, because the effect of negative pressure in valve 3 pressurized gass, sucks the fuel-air mixture body in the Carburetor 11 again.When valve 3 goes to when spark plug 2 places are housed, mixed gas in the mixed gas body cavity 8 all is pressed in the firing chamber 1, spark plug is lighted a fire simultaneously, the then compressed mixed gas blast in the firing chamber 1, and by firing chamber 1 promotion rotor, 9 rotations, when the firing chamber on the rotor 91 goes to outlet pipe 13 places, waste gas is discharged.When rotor 9 is rotated further the ingress of Carburetor 11, enter next acting action, institute's work is through pto 12 outputs.

This valve compression type rotary engine structure is simple, and volume is little, start rapidly, running steadily, reliable, can on rotor, increase a plurality of compression valves and firing chamber if needed, also can increase compressor and transfer diesel engine to than, replacing oil supply system.Place applicable to various required drives.
