Abstract

UN EMPUJA-VALVULAS HIDRAULICO (10) PARA LAS VALVULAS DE UN MOTOR INCLUYE UN PAR DE PISTONES (PCF, PVD) QUE DEFINEN UNA CAMARA DE PRESION (CP) ENTRE LOS MISMOS Y UN PISTON SEPARADO DE AJUSTE DEL HUELGO (PLA) QUE DEFINE UNA CAMARA DE AJUSTE DEL HUELGO (CLA) CON UNO DE LOS PISTONES DEL PAR. ESTRUCTURAS DE VALVULA DE PASO UNICO (V) PERMITEN EL FLUJO DE FLUIDO DESDE LA CAMARA DE PRESION (CP) A LA CAMARA DE AJUSTE DEL HUELGO (CLA), DESPLAZANDO CON ELLO AL PISTON DE AJUSTE DEL HUELGO (PLA) PARA AJUSTAR, A SU VEZ, EL HUELGO DE LA VALVULA. SE PROPORCIONAN TAMBIEN FUNCIONES DE AMORTIGUACION DEL MOVIMIENTO DURANTE UNA CARRERA DESCENDENTE DE LOS PISTONES EMPUJADORES (PCF, PVD, PLA) MEDIANTE UNA CAMARA AMORTIGUADORA DE LA VALVULA (CD) Y CONDUCTOS DE FLUIDO (90B, 112) ENTRE LAS CAMARAS DE PRESION Y AMORTIGUADORA (CP Y CD, RESPECTIVAMENTE).
