Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO INDICADOR DEL NIVEL DE LLENADO DE UNA BOLSA FILTRANTE COLOCADA EN UN ASPIRADOR DE POLVO, EN EL QUE EN LA CAMARA DEL PISTON (16) DE UNA CARCASA DE PISTON ESTA DISPUESTO DESPLAZABLE UN PISTON (21) CONECTADO CON UN MUELLE DE RECUPERACION (20) ASI COMO ACOPLADO DIRECTA O INDIRECTAMENTE CON UN ELEMENTO INDICADOR Y EN EL CUAL DISPOSITIVO, ADEMAS, LA CAMARA DEL PISTON (16) ESTA CONECTADA SOBRE UNO DE LOS LADOS CON LA PRESION DE LA ATMOSFERA Y SOBRE SU OTRO LADO, A TRAVES DE UNA PIEZA DE CONEXION (1) PROVISTA CON UN AGUJERO DE ENTRADA Y DE SALIDA (6, 7), CON LA PRESION NEGATIVA REINANTE EN EL ASPIRADOR DE POLVO. NO SON NECESARIOS ELEMENTOS DE OBTURACION SEPARADOS PARA LA CONEXION DEL DISPOSITIVO INDICADOR PORQUE LA PIEZA DE CONEXION (1) ESTA CONECTADA CON SU AGUJERO DE ENTRADA (6) DE FORMA HERMETICA EN UN AGUJERO DE CONEXION (14) PREVISTO EN UNA PARTE DE LA CAMARA DE PRESION NEGATIVA Y LA CAMARA DEL PISTON (16) ESTA CONECTADA DE FORMA HERMETICA EN EL AGUJERODE SALIDA (7) DE LA PIEZA DE CONEXION (1).THE INVENTION REFERS TO A FILLING LEVEL INDICATING DEVICE FOR A FILTER BAG PLACED IN A DUST VACUUM, IN WHICH A PISTON (21) IS CONNECTED WITH A PISTON IN A PISTON HOUSING. RECOVERY SPRING (20) AS WELL AS DIRECTLY OR INDIRECTLY COUPLED WITH AN INDICATOR ELEMENT AND IN WHICH DEVICE, IN ADDITION, THE PISTON CHAMBER (16) IS CONNECTED ON ONE SIDE WITH THE PRESSURE OF THE ATMOSPHERE AND ON ITS OTHER SIDE, THROUGH A CONNECTION PIECE (1) PROVIDED WITH AN INLET AND OUTLET HOLE (6, 7), WITH THE NEGATIVE NEGATIVE PRESSURE IN THE DUST VACUUM CLEANER. SEPARATE SEALING ELEMENTS ARE NOT NECESSARY FOR THE CONNECTION OF THE INDICATOR DEVICE BECAUSE THE CONNECTION PIECE (1) IS CONNECTED WITH ITS INLET HOLE (6) IN A CONNECTION HOLE (14) PROVIDED IN A PART OF THE CHAMBER OF NEGATIVE PRESSURE AND THE PISTON CHAMBER (16) IS CONNECTED HERMETICALLY IN THE HOLE OF THE OUTLET (7) OF THE CONNECTION PART (1).
