Abstract

UN DISPOSITIVO TENSOR PARA MECANISMOS DE CADENAS O CORREAS, CON UN EMBOLO DE AMORTIGUACION (3) EN UN DEPOSITO CILINDRICO (1), QUE SE IMPULSA POR UN RESORTE DE PRESION (4), QUE SE ENCUENTRA EN EL DEPOSITO (1), EN EL SENTIDO DE TENSION DE LAS CADENAS. ENTRE EL FONDO DEL DEPOSITO (2) Y EL EMBOLO DE AMORTIGUACION (3), SE ENCUENTRA UN ESPACIO DE ALTA PRESION (8) PARA LIQUIDO DE PRESION. ESTE SE CIERRA CON UNA VALVULA DE RETROCESO (8) FRENTE A UN ESPACIO DE SUMINISTRO DE ACEITE (5), Y SE ABRE POR UNA HENDIDURA (14) FORMADA POR EL ORIFICIO DE CONDUCCION (15) DEL DEPOSITO (1) Y EL EMBOLO DE AMORTIGUACION (3). EN FUNCIONAMIENTO, EL DISPOSITIVO TENSOR TIENE EL ESPACIO DE ALTA PRESION DEL LIQUIDO DE PRESION, A CAUSA DE LAS DIFERENCIAS DE VISCOSIDAD, MAYOR EN ESTADO FRIO QUE EN ESTADO CALIENTE. SEGUN EL INVENTO, EL ESPACIO DE ALTA PRESION (9) SE LIMITA POR UN EMBOLO ADICIONAL QUE ACTUA COMO EMBOLO DE SOBREPRESION (10). ESTE SE DESLIZA SOLO EN EL SENTIDO DE UN AUMENTO DEL VOLUMEN DEL ESPACIO DE ALTA PRESION (9) CUANDO LA VISCOSIDAD DEL ACEITE DE PRESION SE SITUA SOBRE UN VALOR LIMITE DETERMINADO, A CAUSA DE NO HABER ALCANZADO AUN LA TEMPERATURA DE FUNCIONAMIENTO.
