Abstract

El motor de combustión interna de tres tiempos con transmisión de movimiento hidráulica utiliza el movimiento oscilatorio de un pistón doble (2) producido por las explosiones de combustible en las cámaras de combustión (6), para mover un bombeador (7) que al moverse succiona aceite desde un estanque (15) y envía pulsos de aceite hacia un acumulador (16) y una válvula reguladora de flujo (17), que transforman los pulsos en un flujo continuo que mueve un motor hidráulico (18), cuyo eje de salida es el eje de salida del motor de tres tiempos. El motor es de tres tiempos, porque tiene un tiempo de compresión, un tiempo de expansión y un tiempo en que el pistón doble permanece detenido, tiempo en el cual se realiza el ciclo de abertura y cierre de las válvulas de escape (10) y admisión (9). El pistón doble se detiene por un equilibrio de fuerzas entre la presión de los gases combustionados sobre el pistón doble y la suma de las fuerzas de la presión de compresión sobre el pistón doble y la presión hidráulica sobre el bombeador, cuando se liberan los gases combustionados, la válvula de bloqueo (14) impide el movimiento del pistón doble hasta el momento de producirse la inyección de combustible y la ignición.The three-stroke internal combustion engine with hydraulic movement transmission uses the oscillatory movement of a double piston (2) produced by the explosions of fuel in the combustion chambers (6), to move a pump (7) that when moving sucks oil from a tank (15) and sends oil pulses to an accumulator (16) and a flow regulating valve (17), which transform the pulses into a continuous flow that moves a hydraulic motor (18), whose output shaft is the output shaft of the three-stroke engine. The engine is three-stroke, because it has a compression time, an expansion time and a time in which the double piston remains stopped, time in which the opening and closing cycle of the exhaust valves (10) and admission (9). The double piston is stopped by a balance of forces between the pressure of the combusted gases on the double piston and the sum of the forces of the compression pressure on the double piston and the hydraulic pressure on the pump, when the combusted gases are released. , the blocking valve (14) prevents the movement of the double piston until the moment of fuel injection and ignition.
