Description

Full cycle rotary piston type internal-combustion engine

The utility model belongs to rotary piston type internal combustion engine.

In existing technology, internal-combustion piston engine needs to-and-fro motion and does work, and four strokes have only a stroke acting, need distribution devices such as connecting rod, bent axle, valve and split axle.Its shortcoming is: complex structure, efficient are low.

The purpose of this utility model is: make a kind of complete alternation rotary piston type internal combustion engine, make internal-combustion engine without distribution devices such as bent axle, connecting rod, valves, do not have toward recurrent images, but directly drive boss rod by same direction rotation acting, and four working strokes of internal-combustion engine are carried out and the complete alternation continuous doing work simultaneously by piston.

Technical solution of the present utility model is: utilize two pairs of pistons to be divided into four spaces in the body of garden tubular, do suction, pressure, quick-fried, row's air chamber respectively, utilize helical pressure friction and the inertia trend of work of every pair of piston of control automatically, make an inner carrier by certain orientation running acting and the output of control power automatically.

The utility model has the advantages that:

1, distribution devices such as no bent axle, connecting rod, valve are simple in structure.

2, four working strokes are carried out simultaneously, the efficient height.

3, not reciprocal, circulating continuous rotating operation, transmitting torque is even.

4, volume is little, power is big.

Below in conjunction with the description of drawings most preferred embodiment.

Fig. 1 is the schematic representation of two pairs of pistons.

Fig. 2,3,4,5 is the pistons work schematic diagram.

Fig. 6 is the schematic representation of helical pressure friction automatic controller.

This internal-combustion engine is the drum barrel 7 of an annular, and there are two pairs of rotary- pistons 1,3 and 5,6 in two ends in the tube, and will be divided into four spaces in the tube with the lid sealing.Two pairs of pistons 1,3 are with the 5, the 6th, by arbor pin 4 relative combining, and can relatively rotate and rotate in the same way by axis with arbor 2, the two pairs of pistons 1,3 and 5,6 have just formed four air chambers that can change volume size in the annular drum barrel 7 of sealing, and four air chambers are respectively suction, pressure, quick-fried, exhaust chamber, and work simultaneously, as quartastroke engine.

Explanation is in the working condition of rotation each cylinder during the halftime now.Fig. 2 is in spark plug 10 ignition points for the air chamber between the piston 1 and 5, so compressed gas takes fire, forces this gas chamber volume to become big.Expanding gas did one's utmost to push open piston 1 and 5 after Fig. 3 represented gaseous combustion, piston 1 and 5 all was the clockwise direction rotation originally, clockwise direction quickened rotation after piston 1 was subjected to the thrust of gas, piston 5 suffered thrusts are to hold it back to turn clockwise, but under the effect of Fig. 6 helical pressure friction automatic controller, make the piston 5 can only clockwise direction rotation or slack, air chamber between the piston 1 and 6 and outlet pipe 8 are connected exhaust simultaneously, air chamber between the piston 6 and 3 and sucking pipe 9 are connected air-breathing, and the gas of the air chamber between the piston 3 and 5 is in compression.When Fig. 4 represented The work is nearly finished, piston 1 did not also reach to relief opening 8 during owing to piston 1 and 5 outburst work, and the air chamber between the piston 1 and 5 is to fire pressurized gas, and the air chamber between the piston 5 and 3 is compressed pressurized gas.Fig. 5 represents because the rotatory inertia of piston 1 and 3 makes the rotation in the direction of the clock simultaneously of 1,3 and 5,6 two pairs of pistons of piston.When the position of piston 5 and 3 arrived ignition point, the air chamber between the piston 1 and 5 had also reached exhaust condition simultaneously, and the air chamber ignition operation between the piston 5 and 3 has promptly reached the working state of Fig. 2 again, thereby had reached continuous operation, complete alternation acting.

The following describes the working principle of helical pressure friction automatic controller.This device is to utilize the friction of rotatory inertia and helical pressure to control automatically that the two pairs of pistons are needed at work to be stopped or rotating to reach two pairs of piston institute works are exported automatically.Boss rod 11 and control wheel 14 are connected by screw key 15, when piston is stressed when rotating in the direction of the clock, drive 14 rotations of control wheel by 11 of boss rods, because effect of inertia makes control wheel 14 to left movement and gear 13 frictional engagement, just by the helical pressure friction rotating power of piston 1 has been passed to gear 13.Because boss rod 11 all is with bearing 17 supportings with support 12, gear 13, brake holder 16, so 1 in piston drives boss rod 11, control wheel 14 and gear 13 rotations.If piston 1 and 3 is firing the position; when just piston 1 will be rotated counterclockwise when outburst is lighted; because control wheel 14 and gear 13 are to rotate in the direction of the clock; as long as boss rod 11 1 stops or rotating speed is lower than control wheel 14; control wheel 14 breaks away from gear 13 immediately and moves right with brake holder 16 and combine under the effect of inertia and helical pressure; gear 13 continuation rotations this moment; and control wheel 14 has been braked boss rod 11 with brake holder 16 under the effect of helical pressure running; force piston 1 and 3 to rotate in the direction of the clock or slack, and can not counterclockwise rotate.When piston 1 and 3 rotated in the direction of the clock, control wheel 14 broke away from brake holder 16 under the effect of helical pressure immediately automatically, and combines with gear 13.Every pair of piston is all installed a cover helical pressure friction automatic controller separately like this, with a conduction axis and two gears and two gear 13 engagements, so just can make two pairs of pistons alternately continuously power be passed to conduction axis when work then.Outwards output has reached the running and the power output of robot brain device.
