Description

Birotor type engine

The utility model relates to a kind of new work engine, and this motor is a rotator type.Its main structure is: internal rotor, external rotor, cylinder body, inner end cap, outer end cap etc., and simple in structure.

Existing internal combustion is piston type, this kind engine structure complexity, power loss is bigger, for overcoming the above problems, Germany engineer Fu Likesi wankel, proposed the imagination of rotor motor first, and made model machine, test result is more satisfactory, but because at short notice, it is serious that rotary piston is swept the angle, polishing scratch occurs, thereby the sealing of motor is damaged, cause output power to descend, because sealing problem never can be solved well, so use value is not high, fails so far to promote the use of.

The purpose of this utility model is that a kind of improved rotor motor will be provided, the seal request when it can guarantee rotor motor work, stably outputting power.

The utility model is achieved in that the garden heart with internal rotor is the rotating center of double rotor formula motor, and by being installed in internal rotor garden pto outputting power in the heart, external rotor rotates along inboard wall of cylinder block, the external rotor inwall is the pentagon cavity, internal rotor just is installed in this cavity, form the dual rotary piston of double rotor formula motor, and in cylinder body, do differential rotation in the same way.

Internal rotor is entity four teeth, in its heart position, garden a pto is installed, and the pentagon cavity of external rotor inwall is divided into five independently cavitys by four teeth of internal rotor, and both sides seal with inner end cap, so far form five independent sealed active chambers.

When the A active chamber passes through inlet hole, the roller seating space hole of A active chamber external rotor and the inlet hole of cylinder body are connected, shown in figure (3), because the A active chamber is after passing through exhaust port, before inlet hole, this chamber volume increases gradually, produce part pull of vacuum (being negative pressure), fuel mixture is inhaled in the A active chamber, and when dual rotary piston continued rotation, the mixed gas that enters the A active chamber then was compressed, when the mixed gas of A active chamber is compressed to minimum volume, the roller seating space hole of A active chamber is just in time connected with spark-plug hole, shown in figure (4), at this moment, spark plug sparking, the mixed gas that ignites makes its acting of expanding, and promotes dual rotary piston rotation, each roller seating space hole of external rotor all produces power stroke one time by spark plug the time, in other words: dual rotary piston whenever rotates a circle, and just produces power five times, more than the wankel machine five times.The birotary engine outputting power almost is continuous thus.Figure (5) is that the A active chamber is in exhaust position.

Concrete structure of the present utility model is provided by following examples and accompanying drawing:

Figure (1) is the axial section according to the double rotor formula motor that the utility model proposes.

Figure (2) is radial section figure.

Figure (3) is the expression suction condition.

Figure (4) is the expression fired state.

Figure (5) is the expression exhaust condition.

Describe in detail according to detail and the working condition that the utility model proposes below in conjunction with figure (1).

This double rotor formula motor comprises: cylinder body (1), cylinder body (1) leave spark-plug hole (12), exhaust port (13), the inlet hole (14) with exterior, exhaust port (13) becomes 110 °～hexagonal angle to be advisable with spark-plug hole (12) conrotatory veer, shown in figure (5), because this moment, the A active chamber did not also reach maximum volume, has bigger pressure in the chamber, when roller seating space hole (16) and exhaust port (13) when communicating, combustion gas under the cavity pressure effect.Dual rotary piston continues rotation when inlet hole (14), shown in figure (3), at this moment the A working chamber volume increases, produce the part pull of vacuum, make air and fuel mixture be inhaled into the A active chamber, inlet hole (14) becomes 170 °～180 ° angles to be advisable with spark-plug hole (12) conrotatory veer, because this moment the A active chamber suction, reach maximum just gradually, when dual rotary piston continues to rotate to spark plug (12), the A active chamber will repeat above process, and what contact with cylinder body (1) inwall is external rotor (2), and external rotor (2) is a garden post cavity, be sliding surface, garden outward, inwall is a pentagon, and the bight is the sliding roller seating space (15) in garden, at the middle part of roller seating space (15) a roller seating space hole (16) is arranged all.There are three meanings in this roller seating space hole (16): one, when roller seating space hole, A chamber (16) rotated to suction port (14), two holes communicated, and at this moment played getter action.When two, continuing to rotate to spark-plug hole (12), at this moment two holes link to each other, and spark plug sparking is lighted mixed gas, shown in figure (4), play the auxiliary firing effect this moment.When three, continuing to rotate to exhaust port (13), two holes communicate, and shown in figure (5), play scavenging action.Internal rotor (3) is housed in the pentagon cavity of external rotor (2), internal rotor (3) is four profiles of tooth, four crowns (17) are arranged, slide along the pentagon inwall of external rotor (2) all the time in the surface, four bent limits of crown (17) and internal rotor (3), and have five lines to be in contact with one another forever, the seal request when guaranteeing the work of this machine.Just internal rotor (3) belongs to eccentric engagement with external rotor (2).Throw of eccentric is e.The compression ratio of this double rotor formula motor is about: 6～21, be applicable to igniting type and compression-ignited two kinds of motors.When making diesel engine, spark-plug hole (12) is located, and the repacking high pressure oil pump gets final product.

Figure (2) is the radial section figure according to the double rotor formula motor that the utility model proposes:

Behind internal rotor (3) embedding external rotor (2), external rotor (2) both sides make internal rotor (3) cut apart five chambeies that external rotor (2) forms with inner end cap (4) sealing that leaves center hole, form five five independent sealed active chambers.To put into cylinder body (1) by the dual rotary piston that internal rotor (3), external rotor (2) and inner end cap (4) are formed again, with the fixing dual rotary piston of the outer end cap (5) that leaves eccentric opening, the garden that pto (6) is fixed on internal rotor (3) in the heart at the two ends of cylinder body (1).With the fixing inner end cap of bolt (7), with bolt (8) fixed outer ends lid.External rotor boss (9) has two effects: the one, and the seal operation chamber, the 2nd, the frictional force of minimizing external rotor (3) and cylinder body (1) inwall, inner end cap boss (11) has two effects: the one, prevent dual rotary piston axial motion, and the 2nd, play the auxiliary seal effect.
