Abstract

SE PRESENTA UN TENSADOR DE CADENA PARA TENSAR UNA CADENA EN UN DISPOSITIVO DE IMPULSION DE UN MOTOR DE COMBUSTION INTERNA QUE COMPRENDE UN PISTON DESPLAZABLE DENTRO DE UNA CAMARA. EL PISTON ES EMPUJADO POR UN MUELLE DE COMPRESION DE MANERA QUE SOBRESALGA DEL ALOJAMIENTO HACIA LA CADENA PARA SUMINISTRAR LA TENSION. LA CAMARA TIENE UNA ENTRADA CONECTADA CON UN SUMINISTRO DE ACEITE DEL MOTOR. EL ACEITE ACTUA SOBRE CADA LADO DEL PISTON SUSTANCIALMENTE CON LA MISMA PRESION, DE MANERA QUE EL PISTON SEA AMORTIGUADO EN AMBAS DIRECCIONES CUANDO SE MUEVE EN LA CAMARA. LAS AREAS SUPERFICIALES DEL PISTON SOBRE LAS QUE ACTUA EL ACEITE PUEDEN SER BASICAMENTE IGUALES, DE MANERA QUE NO SEA SUMINISTRADA NINGUNA FUERZA DE TENSION POR EL ACEITE.
