Abstract

UN TENSOR HIDRAULICO (100) PARA UNA TRANSMISION DE CORREAS O CADENAS (12) DISEÑADO PARA MINIMIZAR LA CANTIDAD DE AIRE PRESENTE EN LA CAMARA DE PRESION. EL TENSOR HIDRAULICO INCLUYE UNA VALVULA COMBINADA DE RETENCION/LIMITACION DE PRESION PARA UTILIZAR CON UNA CAMARA DE PRESION DE PISTON HUECO (110), QUE CONTIENE UN MUELLE PARA EMPUJAR EL PISTON HACIA EL EXTERIOR DEL AGUJERO. EL CUERPO DE VALVULA ESTA DISEÑADO PARA REDUCIR EL VOLUMEN DE FLUIDO CONTENIDO EN LA CAMARA DE PRESION Y MINIMIZAR LA CANTIDAD DE AIRE QUE PUEDE QUEDAR OCLUIDA EN LA CAMARA DE PRESION, MEJORANDO ASI EL COMPORTAMIENTO DEL TENSOR.
