Description

Revolving cylinder engine

Technical field:

The present invention relates to technical field of engines, particularly revolving cylinder engine.

Background technique:

With the open-cycle engine of air as oxygenant and working medium, be one of most important type of motor, common Reciprocating engine, internal-combustion engine, air-flow turbine, air breathing engine all belong to this type.The common feature of this class motor is that its work cycle all comprises air inlet, air compression, air and fuel mix burning and expand acting, four processes of exhaust.Traditional Reciprocating engine is that fuel combustion is done work to piston, the energy that acts on piston head is exported from bent axle behind piston, connecting rod, there is following shortcoming in it: because of four working procedure of air inlet, compression, work by combustion and exhaust are carried out in same cylinder body, it is insufficient that fuel combustion is expanded, so the heat energy that waste gas is taken away, kinetic energy is more and noise is big; It is subjected to structural limitations and causes oil gas mixed short with combustion process, thereby makes burning insufficient, so combustion efficiency is low and exhaust emission is big.

Summary of the invention:

The objective of the invention is provides a kind of fuel combustion sufficient revolving cylinder engine at the deficiencies in the prior art.

For achieving the above object, the present invention adopts following technological scheme:

Revolving cylinder engine, it includes stator, rotates the rotating shaft, the spark plug that are arranged in the bore of stator, the both sides of stator interior are provided with eccentric arcwall, stator interior is provided with the commentaries on classics cylinder, change the coaxial rotating shaft middle part that is fixed on of cylinder, change and offer the cylinder that radially connects on the cylinder, slide in the cylinder and be provided with direction opposite two and can be drawn piston by radially outward to the bore of stator perisporium, constitute the firing chamber between two-piston and the cylinder, rotating shaft is a hollow shaft, its inner chamber is communicated with firing chamber on changeing cylinder, being inserted with the spark plug that stretches into the firing chamber on the commentaries on classics cylinder.

Described rotating shaft is divided into front and back two-part by changeing cylinder, is equipped with valve between two-part inner chamber and the firing chamber before and after the rotating shaft.

Be fixed with the cam bit corresponding on the described stator with valve.

Offer the channel suspending rail consistent with its perisporium shape on the described stator interior perisporium, piston is provided with roller, and roller is arranged in the channel suspending rail.

Beneficial effect of the present invention is: the present invention includes stator, rotation is arranged on the rotating shaft in the bore of stator, spark plug, the both sides of stator interior are provided with eccentric arcwall, stator interior is provided with the commentaries on classics cylinder, change the coaxial rotating shaft middle part that is fixed on of cylinder, change and offer the cylinder that radially connects on the cylinder, slide in the cylinder and be provided with direction opposite two and can be drawn piston by radially outward to the bore of stator perisporium, constitute the firing chamber between two-piston and the cylinder, rotating shaft is a hollow shaft, its inner chamber is communicated with firing chamber on changeing cylinder, change on the cylinder and be inserted with the spark plug that stretches into the firing chamber, when changeing the cylinder rotation, piston slides outside cylinder under action of centrifugal force, and replaces the bore of stator perisporium, the rotation of changeing cylinder makes piston reciprocating under the constraint of cylinder, and two-part inner chamber constitutes suction port and relief opening respectively before and after the rotating shaft; Piston from the solstics of eccentric arcwall to the process of closest approach motion, air enters the firing chamber from suction port, the distance of two pistons reduces gradually and the air in the firing chamber is compressed, piston motion when nearest, fuel in the firing chamber and air mixing work by combustion; Piston moves to the solstics from closest approach then, the distance of two pistons increases gradually, and waste gas discharged from relief opening, to change cylinder and rotate once enclosing the work cycle process of finishing, acting is once, fuel and air mixing are effective, fuel combustion and expansion are abundant, and output torque is big, and noise is little, stable working, simple in structure.

Description of drawings:

Fig. 1 is a sectional view of the present invention;

Fig. 2 is the phantom of A-A direction among Fig. 1;

Fig. 3 is a working state sectional view of the present invention;

Fig. 4 is the sectional view of the another kind of way of example of the present invention.

Embodiment:

The present invention is further illustrated below in conjunction with accompanying drawing, see Fig. 1～3, revolving cylinder engine, it includes stator 1, rotation is arranged on the rotating shaft 2 in stator 1 inner chamber, spark plug 3, the both sides of stator 1 inside are provided with eccentric arcwall 11, stator 1 inside is provided with changes cylinder 4, change cylinder 4 coaxial rotating shaft 2 middle parts that are fixed on, change and offer the cylinder 41 that radially connects on the cylinder 4, slide in the cylinder 41 and be provided with direction opposite two and can be drawn piston 5 by radially outward to stator 1 inner chamber perisporium, constitute firing chamber 42 between two-piston 5 and the cylinder 41, rotating shaft 2 is a hollow shaft, its inner chamber is communicated with firing chamber 42 on changeing cylinder 4, being inserted with two spark plugs 3 that stretch into firing chamber 42 on the commentaries on classics cylinder 4.

Rotating shaft 2 is divided into front and back two-part by changeing cylinder 4, the two-part inner chamber in rotating shaft 2 front and back constitutes suction port 21 and relief opening 22 respectively, be respectively equipped with valve 6 between firing chamber 42 and suction port 21, the relief opening 22, be fixed with the cam bit 12 corresponding on the stator 1 with valve 6, valve 6 is controlled the switching of suction port 21 and relief opening 22 respectively, change the moving circle of cylinder 4 revolutions, valve 6 contacts the switching of once controlling suction port 21 and relief opening 22 with cam bit 12.

When changeing cylinder 4 rotations, piston 5 slides outside cylinder 41 under action of centrifugal force, and replaces stator 1 inner chamber perisporium, and the rotation of changeing cylinder 4 makes piston 5 reciprocating under the constraint of cylinder 41; Piston 5 from the solstics of eccentric arcwall 11 to the process of closest approach motion, air enters firing chamber 42 from suction port 21, the distance of two pistons 5 reduces gradually and the air in the firing chamber 42 is compressed, piston 5 moves to when nearest, fuel in the firing chamber 42 and air mixing work by combustion; Piston 5 moves to the solstics from closest approach then, the distance of two pistons 5 increases gradually, and waste gas discharged from relief opening 22, to change cylinder 4 and rotate once enclosing the work cycle process of finishing, acting is once, fuel and air mixing are effective, fuel combustion and expansion are abundant, and output torque is big, and noise is little, stable working, simple in structure.
