Abstract

En una cámara de combustión de un motor de combustión de pistón hay un pistón desplazable que se puede mover progresivamente hacia arriba o hacia abajo entre una posición de giro superior e inferior. El desplazamiento se realiza a través de un motor de paso controlado eléctricamente que se conecta al pistón a través de un enlace hidráulico, que incluye un bloqueo hidráulico. El bloqueo se desactiva durante el desplazamiento de un cierto número de pasos hacia arriba o hacia abajo ordenados por un sistema de control del motor, y cuando finaliza el desplazamiento, el bloqueo se activa por dicho sistema de control del motor y el pistón móvil se bloquea en una cierta posición ordenada por el sistema de control del motor.
