Abstract
The present utility model is a free-piston engine comprising pinions, with various stages, providing excellent efficiency and control.
Description
- This Patent Application for a Utility Model pertains to the field of motor mechanics in general and to the use of compressed gas in particular.
- The applicant is owner of several patents in the same technical field including automotive field.
- The object of this invention has the advantage of granting a greater use to the energy due to the following reasons, among others:
- a) Less friction due to the exclusively rectilinear movement of the pistons and their rod.
- b) Use of the pressure decrease in each stage, each of them including greater diameter cylinders as Force=Pressure×Surface and decreasing pressure and increasing diameter of the piston of the following stage increases, the drive force value can be maintained.
- c) When the gas expands, its temperature decreases; but when ambient air penetrates into the cylinders, usually at a higher temperature, that also leads to an increase in the pressure in the system.
- The engine comprises a compressed-air tank, with an exhaust valve, pipes and valves that link said tank with motor pistons, each of them located at their respective cylinder. The rod of each cylinder is connected to a chain, which is linked at its other end to a spring. Said spring is fixed, at its other end, to a point.
- The chain(s) of each piston are each connected to a pinion and these are located in a same axis that is the motor axis of the device where the engine is applied, whether it is a car, a generator or another device.
- The pipe links the exhaust of the tank valve with derivations to each cylinder. Each derivation is preceded by a valve and another valve is located at the end of said pipe.
- As it arises from what was exposed, the engine may be provided with several pistons, all of them located in the same side of the motor axis or half on one side and the other half on the other side, opposing the former, which allows a greater use of the energy.
- The engine also includes an opening and closing command system of the valves in due time and form which may be constituted by known means such as PLC, microcomputer or mechanical means, etc.
- In order to make it easer to understand the prior description and its functioning, a drawing of a preferred example is added, which is described next.
- When the vehicle is stopped, tank 1 with pressure air and
pistons valve 3 opens. The air goes fromtank 1 tocylinder 4 throughpipe 2 andvalve 3. The air pushespiston 5, which pullsaxis 6, which pullschain 8, which makespinion 7 turn, which makesaxis 10 turn, which makes the vehicle wheel turn. When the desired amount of air has entered intocylinder 4,valve 3 shuts andvalve 11 opens. The air goes fromcylinder 4 to 13 throughpipe 12 andvalve 11. The air pushespiston 14, which pullsaxis 15, which pullschain 24, which makespinion 23 turn, which makesaxis 10 turn. Valve 16 opens, the air goes throughcylinder 13 tocylinder 18 throughpipe 17 andvalve 16. The air pushespiston 19, which pullsaxis 20, which pullschain 25, which makespinion 22 turn, which makesaxis 10 turn. Valve 21 opens. The air ofcylinders pipes valves - The pistons go back to their initial position, that is, the point of their route which is closest to the valves, carried by the force of
springs chains axis respective inlets - On of the ways in which to make this system work is the following:
- When
piston 5 gets to the end of its route,valve 11 opens. This can be done in several ways; one of them is that, when getting to the end of its route,axis 6 touches a mechanism that opens the valve mechanically. Another way is that, when getting to the end of its route,axis 6 closes an electric circuit that makes a solenoid work and opensvalve 11. When air goes fromcylinder 4 to 13, it makespiston 13 work, and when it gets to the end of its route, it opensvalve 16, in the same way thatvalve 11 was opened. Now the air goes fromcylinder 13 to 18, makingpiston 19 work. Whenpiston 19 gets to the end of its route, it opensvalve 21, thus allowing the air to escape to the atmosphere. Now the 4 pistons are brought to their initial position by the springs, that is, to the closest to the valves (allowing the entrance of ambient air in said cylinders through theirinlets spring 8, followed in strength byspring 24, followed in strength byspring 26, forpiston 4 to get to the initial position in the first place, then 14 and then 19. Whenpiston 5 gets to the initial position, it closesvalve 11. Whenpiston 14 gets to the initial position, it closesvalve 16. Whenpiston 19 gets to the initial position, it closesvalve 21. Once the three pistons get to the initial position,valve 3 may be opened in order to repeat the cycle. The ideal thing is for the air to come out at atmospheric pressure, but it can come out at a higher pressure. Also,valve 3 can be left open even after one or several pistons have finished their route. - In the case that a small amount of air has entered into the pistons and some of them or all of them did not go all the way,
valves - Another way of making this system work would be:
- Placing a piston that pulls in the same direction that the other but in the opposite sense in a same axis, that is, if one pulls from the top, the other pulls from the bottom of the axis. Everything is connected in the same way, but both pistons will be linked with one another. Two advantages are accomplished in this way: not losing energy in the springs and giving higher speed to the backward movement of the piston, with which a greater power in the engine is accomplished. When a piston is working, it is taking the other to the initial position.
- Note that the free-wheel and pinion engine, object of this invention, has a great number of advantages, but one of the most important ones is that it does not need a heat exchanger since the engine in itself is an excellent heat exchanger. As the air expands and cools, the piston heats. This is due to the fact that the atmosphere air, possibly at a higher temperature, penetrates into the cylinder through the vents that it has to that effect, thus increasing the temperature of the cylinder, mainly in its internal side, which will then heat the air when the piston works. Also, the piston axis is heated when going out into the atmosphere and it will heat the air when the piston works. In the high pressure piston there is a separation of 2 mm between the cylinder and the axis, which makes the system heat quickly. Besides, external ailerons can be placed for further heating.
- In a car engine, for example, 12 pistons can be placed and these work in decompressions in groups of three, making them work in order; a first group of three, a second group of three, a third group of three and a fourth group of three, so that when the first group has to work again, it is already heated.
- The engine can also be larger and with more pistons, in order to achieve a better functioning as a heat exchanger.
- The axis with a screw where the pinions are placed may comprise a single piece. This axis can also work as a crankshaft. In order to fasten it better, some pieces screwed from the inside and flat on the outside can be placed where the ball bearings that hold the chassis go, which is equal to the conventional bedplates.
