Abstract

SE DESCRIBE UN ELEMENTO HIDRAULICO DE NIVELACION DE JUEGO (3) EN EL ACCIONAMIENTO DE LA VALVULA DE UN MOTOR DE COMBUSTION INTERNA, QUE INCLUYE UNA PIEZA CILINDRICA CERRADA (4) Y UNA PIEZA DE EMBOLO (6) DENTRO DE ESTA. EN LA PIEZA DE EMBOLO (6) UN ESPACIO DE RESERVA (10) CON ACEITE LUBRICANTE, QUE ESTA SEPARADO MEDIANTE UN CANAL DE UNION (11) DEL ESPACIO DE PRESION (9). PARA PODER DESCONECTAR LA FUNCION DE NIVELACION DE JUEGO AL FRENAR EL MOTOR, SE PREVEE UNA VALVULA DE BLOQUEO (16) EN EL ESPACIO DE RESERVA, A TRAVES DE LA QUE EL CANAL DE UNION (11) DEPENDIENDO DE LA PRESION DEL ACEITE HIDRAULICO EN EL ESPACIO DE RESERVA 810) ES DIRIGIDO.
