Description

Y type rotary engine

Technical field

The utility model relates to a kind of rotary engine.

Background technique

Conventional engines adopts Piston Compression gas, and gas is lighted the back thermal expansion force and promoted piston again by connecting rod promotion crankshaft rotating, caused the loss of certain torsion in this process, and the conventional engines volume of three cylinder-bore is bigger, and fabricating cost is higher.

The model utility content

The utility model provides a kind of Y type rotary engine, avoided conventional engines because the loss of the torsion that structural defective causes, and fabricating cost is low.

The purpose of this utility model is come specific implementation by the following technical programs:

A kind of Y type rotary engine comprises rotor housing, rotor, a plurality of piston crank mechanism and location centrifugal shaft,

Described rotor is installed in described rotor housing inside, cooperates with described rotor housing inner rotation,

Described location centrifugal shaft is installed in described internal rotor,

Described piston crank mechanism is installed in the interior cylinder-bore of rotor housing, and evenly distributes around the center of rotor housing, connects by described location centrifugal shaft between a plurality of described piston crank mechanisms.

Further, described piston crank mechanism and described cylinder-bore all have three.

Further, described piston crank mechanism comprises piston and connecting rod.

Further, the rotor surface between adjacent two piston crank mechanisms is provided with the propelling groove.

Further, the curve bath of described propelling groove for extending inward by described rotor exterior.

Further, on outer wall, be equipped with and advance slot seal and cylinder-bore Sealing near the described rotor of the darker side of described propelling groove,

Described propelling slot seal and described cylinder-bore Sealing and described rotor housing inwall are slidingly matched.

Further, leave the space that supplied gas flows between described rotor housing and the described rotor.

Further, described rotor housing is provided with relief opening and suction port,

Described relief opening is arranged on the nearer side of distance described location centrifugal shaft, is communicated with described rotor housing inner space,

Described suction port is arranged on the nearer side of distance described location centrifugal shaft, is communicated with described rotor housing inner space.

Though it has adopted Piston Compression the utility model, the rotor rotation drives the relative rotor motion of piston, under the effect of directed eccentric shaft, piston moves up and down, finishes four strokes, when working stroke, its expansive force directly promotes rotor and advances groove, make the rotor rotation, eliminated because expansive force promotes piston and promoted the torsion loss of crankshaft rotating again by connecting rod, thereby increased the power and the rotating speed of rotor.Though the conventional engines volume of same three cylinder-bore is compared, its reduction in bulk one times, manufacture cost is far below conventional engines.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1-Fig. 4 is the running schematic representation of the described cold Y type rotary engine of the utility model embodiment.

Embodiment

As Fig. 1-shown in Figure 4, the described a kind of Y type rotary engine of the utility model embodiment comprises rotor housing 1, rotor 2, a plurality of piston crank mechanism and location centrifugal shaft 4,

Rotor 2 is installed in rotor housing 1 inside, cooperates with rotor housing 1 inner rotation,

Location centrifugal shaft 4 is installed in rotor 2 inside,

Piston crank mechanism is installed in the cylinder-bore 21 in the rotor housing 1, and evenly distributes around the center of rotor housing 1, connects by location centrifugal shaft 4 between a plurality of piston crank mechanisms.

Piston crank mechanism and cylinder-bore 21 all have three.

Piston crank mechanism comprises piston 3 and connecting rod.

Rotor 2 surfaces between adjacent two piston crank mechanisms are provided with and advance groove 22.

Advance the curve bath of groove 22 for extending inward by rotor 2 outsides.

On outer wall, be equipped with and advance slot seal 23 and cylinder-bore Sealing 24 near the rotor 2 that advances groove 22 darker sides,

Advance slot seal 23 and cylinder-bore Sealing 24 to be slidingly matched with rotor housing 1 inwall.

Leave the space that supplied gas flows between rotor housing 1 and the rotor 2.

Rotor housing 1 is provided with relief opening 11 and suction port 12,

Relief opening 11 is arranged on the nearer side of distance location centrifugal shaft 4, is communicated with rotor housing 1 inner space,

Suction port 12 is arranged on the nearer side of distance location centrifugal shaft 4, is communicated with rotor housing 1 inner space.

Be intake stroke of the present utility model as shown in Figure 1, the cylinder-bore 21 of rotor 2, piston 3 and 22 combinations of propelling groove can be divided into three groups of A, B, C, and 120 ° uniform, advance 23 of groove sealings and 24 execution of cylinder-bore Sealing respectively to organize the seal operation of working surface.

The valve of rotor housing 1 adopts side-mounted.Rotor 2 rotations, the IO Intake Valve Opens on rotor housing 1 right side, the piston 3 in the A group cylinder-bore 21 moves to lower dead center to rotor 2 centers under the effect of location centrifugal shaft 4, the inspiration fuel mixture, air fuel ratio 14.7:1 is intake stroke.

With rotor 2 rotations, piston 3 upwards moves to top dead center compression fuel mixture from lower dead center.

As shown in Figure 2, implement compression stroke, compression ratio 8:1 reaches petrolic compression ratio requirement.

The cylinder-bore 21 of A group and propelling slot seal 23 are positioned at relief opening 11 during combustion, exhaust valve closing, piston 3 is positioned at top dead center, firing chamber 13 has possessed the condition of high pressure inflammable mixture, the punctual in advance igniting of spark plug 5 before piston 3 arrives top dead center, mixed gas is lighted, and powerful detonation expansive force promotes to advance groove 22 to make rotor 2 rotations.

Working stroke as shown in Figure 3.

Rotor 2 torques of this motor working stroke are 240 °, reason is that the A group is done work to suction port 12 from relief opening 11, the acting torque is 180 °, again from suction port 12 to relief opening 11 Rotate 180 ° again, and cylinder-bore 21 and propelling groove 22 front and back Sealings are at a distance of 120 °, the A group is wanted exhaust also need rotate 60 ° and could be arrived 11 relief openings so, and this its detonation expansive force of 60 ° of torques is still promoting rotor 2 rotations.So rotor 2 working strokes are 180 °+60 °.

When the A of rotor 2 group cylinder-bore 21 to relief opening, exhaust valve is opened on time, piston 3 moves to top dead center, and waste gas is released, and finishes exhaust stroke.As shown in Figure 4.

Above-mentioned is a surface of rotor, the working stroke analysis of A group.Rotor is made up of three working groups, and when air inlet took place the A group, the B group produced acting, and the C group produces exhaust, rotor Rotate 180 °, when the C group produced air inlet, the A group produced compression, and the B group is carried out exhaust, rotor Rotate 180 °, with its periodic duty, rotor whenever circles partly has twice work doing to impact.

Though it has adopted Piston Compression the utility model, the rotor rotation drives the relative rotor motion of piston, under the effect of directed eccentric shaft, piston moves up and down, finishes four strokes, when working stroke, its expansive force directly promotes rotor and advances groove, make the rotor rotation, eliminated because expansive force promotes piston and promoted the torsion loss of crankshaft rotating again by connecting rod, thereby increased the power and the rotating speed of rotor.Though the conventional engines volume of same three cylinder-bore is compared, its reduction in bulk one times, manufacture cost is far below conventional engines.
