Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine, and more particularly, to a valve opening / closing device capable of stably and rotating at high speed in a two-stroke manner by sucking and exhausting compressed air.
An engine is a mechanical device that converts heat energy into mechanical energy and supplies it to the outside. It can be roughly classified into a heat engine, an internal combustion engine, and a motor. In particular, since the engine needs to burn fossil fuel to obtain power, it is made of materials that can withstand high temperatures and high pressures. These engines are used as power generation devices in real cars, generators and various industries.
On the other hand, in order to easily understand the internal structure and the operating principle of such an engine in schools and industrial sites, an educational engine is manufactured and used as in Patent Documents 1 to 3.

However, the following problems arise in the engine used for the purpose of existing learning or the like.
(1) Most of the existing engines are manufactured in the form of four-stroke engines leading to the suction-compression-explosion-exhaust sequence. Therefore, it is difficult to accurately implement the four-stroke order engine.
(2) That is, the four-stroke engine mixes air and fuel and then explodes them to obtain the power required for actual driving. However, since the explosion process can not be implemented in the existing engine, there is a limitation in showing the accurate engine driving state.
(3) Also, if an engine that works like an actual engine is required, such as a radio control car, such an existing engine can not be used. Accordingly, since a large number of motors are used as a power generating means such as an engine, there is a limit to realizing an operation like an actual engine.
(4) On the other hand, a four-stroke sequence is performed by using a fluid such as compressed air as a working fluid. In this case, since the number of rotations through each process is low, .
The present invention takes this point into consideration and constitutes a valve so that the engine can rotate while the valve rotates through intake and exhaust processes in the form of two strokes of compressed air so that the structure is simple and the intake and exhaust operations are directly switched And it is an object of the present invention to provide an engine valve opening / closing apparatus which can rotate at a high speed and obtain the same effect as an actual engine.
Further, according to the present invention, such a valve opening / closing device can be assembled and assembled using a 3D printer, so that anyone can easily and quickly use the opening / closing device by assembling and using, Another object is to provide a valve opening / closing device for an engine that can be mass-produced in a quick and accurate shape.
In order to achieve the above object, an engine valve opening / closing apparatus according to the present invention includes a cylinder head (100) mounted on a cylinder block and adapted to reciprocate a piston by supplying compressed air to the cylinder block Two
Particularly, the
delete
Lastly, the
The valve opening / closing apparatus for an engine according to the present invention has the following effects.
(1) Since the power is obtained by the two-stroke method, the structure is simple and can be easily manufactured. In particular, the rotational force can be obtained through intake and exhaust, and the rotational speed can be increased.
(2) As the number of revolutions increases, it can be applied not only to existing education but also to devices requiring actual engine power such as a radio controlled car (RC car) or a toy car driven by a motor. In addition, it can be utilized for industrial use. In this case, the working fluid is operated by utilizing pulmonary steam.
(3) Since necessary parts are manufactured using 3D printer, necessary parts can be manufactured and used easily and quickly.
(4) In addition, since the parts used in the valve opening / closing apparatus according to the present invention can be easily assembled by hand and can be quickly assembled by hand, anybody can easily assemble or replace damaged parts or the like.
