Description

Technical Field

[0001] The utility model belongs to the technical field of engines, and particularly relates to a rotor engine. Background Art

[0002] With the development of industrial technology, modern engine technology has become more and more perfect, and engines of various structures have been continuously developed. Among them, the rotary engine has attracted attention from all parties because of its unique mechanical structure. However, the lubrication and maintenance of the rotary engine are relatively difficult, and some parts are susceptible to wear, resulting in a relatively short life.

[0003] Secondly, the internal structure of a rotary engine is generally complex, especially the opening and closing structure of its combustion chamber, which is prone to failure after running for a long time. In addition, the combustion chamber of the engine is small, and a large part of the energy is carried away by the exhaust gas, and the energy conversion rate of fuel combustion is not high. Summary of the invention

[0004] The purpose of the utility model is to address the deficiencies of the prior art and to solve the above problems. The utility model provides the following technical solutions: a rotary engine, comprising a cylinder body, a rotor and a cylinder head, a circular channel being arranged in the middle of the cylinder body, a rotor being rotatably arranged inside the circular channel, a receiving groove being arranged at the top end of the circular channel, and a movable valve mechanism being arranged inside the receiving groove and being passively opened and closed as the rotor rotates.

[0005] Furthermore, a stopper is provided on the side wall of the rotor, and an inclined reinforcing rib for lifting the movable valve mechanism is provided on the left side of the stopper. The end face of the stopper is an arc surface, and the end face of the stopper is close to the inner wall of the circular channel, so that a high air tightness is maintained in the chamber;

[0006] The movable valve mechanism includes a stop valve, a baffle is provided at the left end of the stop valve, and the baffle is designed to be arc-shaped for the convenience of the end contacting the rotor. A torque hole is provided at the right end of the stop valve, and a shaft rod matching the torque hole is provided on the side wall of the accommodating groove. A reset torsion spring is also provided in the torque hole, and the reset torsion spring runs through the shaft rod, one end of which is clamped on the cylinder body, and the other end is clamped on the stop valve, so as to provide the stop valve with a rotational force rotating in the direction of the rotor with the shaft rod as the center. A limiting rod is also provided below the accommodating groove to control the distance between the stop valve and the rotor, so that the stop valve can be infinitely close to the rotor without contact friction. A roller is also provided at the position where the bottom end of the baffle first contacts the stop block. Since the roller is arranged at the rear, it does not affect the air tightness of the front end of the baffle. When the stop block on the rotor rotates to the stop valve position, the stop valve is gradually lifted up by the inclined reinforcement ribs, and the roller structure is provided to reduce friction during lifting.

[0007] Furthermore, an oil inlet hole, an ignition hole, a trigger hole and an exhaust hole are arranged on the inner side wall of the circular channel. An ignition device is installed inside the ignition hole. The ignition device is generally a spark plug. A trigger is installed inside the trigger hole and is triggered by contact with a block. The trigger controls the fuel to be input from the oil inlet hole and ignited by the ignition device. As the rotor rotates, the block on the rotor contacts the trigger once per circle. The trigger controls the fuel to enter the combustion chamber and be ignited by the ignition device to drive the rotor to continue rotating.

[0008] The stop valve is twisted and falls close to the outer wall of the rotor, and the baffle separates the annular channel between the rotor and the cylinder body into two chambers. The oil inlet, ignition hole and trigger hole are in the left chamber, and the exhaust hole is in the right chamber. The space of the two chambers changes continuously with the position of the block.

[0009] Furthermore, a regulating valve for adjusting the movable distance of the stop valve is provided on the cylinder body at the movable end of the stop valve, and a shock-absorbing spring is provided at the bottom of the regulating valve. The shock-absorbing spring can reduce the impact of the stop valve on the cylinder body when it jumps up, and can also quickly reset the stop valve. The stop valve is also provided with a pocket groove matching the limit rod.

[0010] Furthermore, a counterweight hole is provided on one side of the rotor close to the stopper, and the number and size of the counterweight holes are specifically set according to the size and weight of the stopper to make the rotor rotate more smoothly. The stopper can be a detachable structure fixed to the rotor by bolts. Since the stopper is easily damaged by impact for a long time during operation, it is set as a detachable structure so that only the stopper can be replaced without replacing all rotor parts. A pulley is provided at the outer end of the rotor, and an annular groove is provided on the pulley. A notch is also provided on the pulley to facilitate applying external force to start the engine.

[0011] Furthermore, the trigger includes a heat-resistant touch rod whose front end is assembled into the combustion chamber, a reset spring and a rear-end trigger switch. When the block rotates and contacts the front-end heat-resistant touch rod, it moves backward to trigger the rear-end trigger switch. The trigger switch controls the fuel to be input from the oil inlet and the ignition device to ignite. The block continues to rotate and the heat-resistant touch rod is reset under the action of the reset spring, ready for the next trigger.

[0012] Furthermore, the fuel passing through the oil inlet hole is compressed by an external compressor to form high-pressure fuel and sprayed into the combustion chamber. The compressor is connected in series to the main shaft of the engine. After the engine runs normally, the main shaft provides power to the compressor so that it works synchronously with the engine.

[0013] Furthermore, the cylinder body edge of the circular channel is provided with an annular array of bolt holes, and the cylinder cover is locked with the cylinder body by bolts.

[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0015] The combustion chamber is a full circle, and the fuel combustion space is large, so that it can be completely burned and the energy of fuel combustion can be converted into mechanical energy to the maximum extent;

[0016] The shut-off valve and trigger are passively triggered by the block through the rotation of the rotor and can be quickly reset, making the entire engine simple in structure and stable in operation;

[0017] The rotor with the function of a flywheel makes the entire internal combustion engine run more smoothly. The exhaust gas is discharged directly from the exhaust hole through the rotation of the rotor and the pressure generated by the block, without the need for an additional exhaust structure.

A limiting rod 702 is also provided below the accommodating groove 4 to control the distance between the stop valve 7 and the rotor 2, so that the stop valve 7 can be infinitely close to the rotor 2 without contact and friction. A roller is also provided at the position where the bottom end of the baffle first contacts the block.

[0034] The inner wall of the circular channel is provided with an oil inlet hole 601, an ignition hole 5, a trigger hole 6 and an exhaust hole 8. A spark plug is loaded inside the ignition hole 5. A trigger that is contacted and triggered by the block 201 is installed inside the trigger hole 5. The trigger controls the fuel to be input from the oil inlet hole 601 and ignited by the spark plug. As the rotor 2 rotates, the block 201 on the rotor 2 contacts the trigger once per circle.

[0037] In a further embodiment of the utility model, a counterweight hole is provided on one side of the rotor 2 close to the block 201, and the number and size of the counterweight hole are specifically set according to the size and weight of the block 201, so that the rotor 2 can rotate more smoothly. The block 201 can be a detachable structure, which is fixed to the rotor 2 by bolts.
