Descripción detallada de la invención Detailed description of the invention
El objeto de la invención se refiere a un dispositivo destinado para regular el movimiento de la válvula de escape en los cilindros (1) de los motores de explosión, concretamente para ir acoplado al eje (2) del mecanismo de movimiento de la válvula de escape, el The object of the invention relates to a device designed to regulate the movement of the exhaust valve in the cylinders (1) of the explosion engines, specifically to be coupled to the axis (2) of the exhaust valve movement mechanism. , he

El dispositivo preconizado consta de un cuerpo (6) que se cierra con una tapa (7), determinando una cámara interior (8) que se llena con aceite. The recommended device consists of a body (6) that closes with a cover (7), determining an inner chamber (8) that is filled with oil.
La cámara interior (8) queda dividida por un tabique compuesto por una parte fija ( 9) y una parte móvil (10), determinando dos compartimentos (11 y 12) que se comunican a través de un orificio (13) que atraviesa a la parte fija (9) del tabique divisor. The inner chamber (8) is divided by a partition composed of a fixed part (9) and a mobile part (10), determining two compartments (11 and 12) that communicate through a hole (13) that crosses the fixed part (9) of the partition wall.
La parte móvil (10) del tabique divisor va incorporada sobre un eje axial (14) que sale al exterior, de manera que dicha parte móvil (10) es susceptible de girar recorriendo angularmente la cámara interior (8) del dispositivo, obligando en ese movimiento a que el aceite contenido en dicha cámara interior ( 8) circule por el orificio (13) entre los compartimentos (11 y 12), en una dirección u otra según sea el sentido del movimiento. The movable part (10) of the dividing partition is incorporated on an axial axis (14) that goes outside, so that said movable part (10) is capable of rotating angularly traversing the inner chamber (8) of the device, forcing in that movement to the oil contained in said inner chamber (8) circulating through the hole (13) between the compartments (11 and 12), in one direction or another depending on the direction of movement.
El orificio (13) se halla calibrado para que el paso del aceite a través de él tenga una resistencia, yendo además dispuesto en relación con dicho orificio The hole (13) is calibrated so that the passage of oil through it has a resistance, also being arranged in relation to said hole

De este modo, mediante acoplamiento del dispositivo por medio de su eje axial (14), respecto del eje (2) del mecanismo de movimiento de una válvula de escape, se consigue que el movimiento de la válvula de escape entre las posiciones de apertura y cierre sea progresivo, debido a la resistencia que opone el dispositivo por la dificultad del paso del aceite a
In this way, by coupling the device by means of its axial axis (14), with respect to the axis (2) of the movement mechanism of an exhaust valve, it is achieved that the movement of the exhaust valve between the opening positions and closing is progressive, due to the resistance that the device opposes due to the difficulty of the oil passing to

Dicha resistencia del dispositivo al movimiento de la válvula de escape de aplicación puede ser regulada mediante el estrangulamiento selectivo del orificio Said resistance of the device to the movement of the application exhaust valve can be regulated by selective throttling of the orifice.

(13) with the plug screw (15), whereby this device of the invention allows to adapt the progressivity of the movement of the application exhaust valve, to determine the operation of the corresponding engine in the desired way.
A ese efecto, el tornillo obturador (15) va dispuesto de forma que puede ser actuado desde el exterior del dispositivo, de modo que no es necesario ningún desmontaje para efectuar la regulación. For this purpose, the sealing screw (15) is arranged so that it can be operated from outside the device, so that no disassembly is necessary to carry out the adjustment.
La parte móvil (10) se prevé además atravesada por un orificio (16), el cual se cierra en un extremo mediante una pletina flexible (17), de forma que cuando la parte móvil (10) gira en un sentido el aceite de la cámara interior (8) pasa a través de ese orificio (16), ya que el propio impulso del aceite obliga a la pletina flexible (17) hacia fuera dejando abierto el paso, con lo cual el efecto de resistencia al giro del eje (14) y por lo tanto al movimiento de la válvula de escape de aplicación, resulta reducido o anulado. The mobile part (10) is also provided to be crossed by a hole (16), which is closed at one end by means of a flexible plate (17), so that when the mobile part (10) rotates in one direction the oil of the inner chamber (8) passes through that hole (16), since the oil impulse itself forces the flexible plate (17) out leaving the passage open, thereby the effect of shaft rotation resistance (14 ) and therefore the movement of the application exhaust valve is reduced or canceled.
Por el contrario, cuando la parte móvil (10) gira en el sentido opuesto al anterior, el impulso del aceite hace que la pletina flexible (17) presione contra esa parte móvil (10) obturando el orificio (16), On the contrary, when the movable part (10) rotates in the opposite direction to the previous one, the impulse of the oil causes the flexible plate (17) to press against that movable part (10) sealing the hole (16),

Por lo tanto, disponiendo la pletina flexible (17) en un lado u otro de la parte móvil (1 O) , se puede adaptar el dispositivo para determinar una acción resistente en relación con un determinado sentido del movimiento de la válvula de escape de aplicación, por ejemplo para que la acción de apertura de la misma se produzca de una manera progresiva y que, sin embargo, el retorno a la posición de cierre se produzca de una manera prácticamente instantánea; o bien, disponiendo Therefore, by providing the flexible plate (17) on one side or the other of the mobile part (1 O), the device can be adapted to determine a resistant action in relation to a certain direction of movement of the application exhaust valve , for example, so that the opening action thereof occurs in a progressive manner and, however, that the return to the closed position occurs virtually instantaneously; or, arranging
