Abstract

UNA CARCASA ENTREETAPAS HECHA DE LAMINAS METALICAS QUE INCLUYE UN CUERPO CILINDRICO PARECIDO A UN RECEPTACULO PROVISTO DE UNA PARED INFERIOR (24) EN UN EXTREMO DEL MISMO Y UN EXTREMO ABIERTO OPUESTO AL ANTERIOR. EL EXTREMO ABIERTO TIENE UNA SUPERFICIE EXTREMA AXIAL (22) Y OTRA INTERNA RADIAL (23) QUE SIRVEN COMO MIEMBRO DE UNA JUNTA DE ENCHUFE QUE SE VA A UNIR A OTRA CARCASA SIGUIENTE. EL CUERPO CILINDRICO PARECIDO A UN RECEPTACULO INCLUYE TAMBIEN UNA PARED LATERAL CILINDRICA (21), UNA PARTE CILINDRICA (25), UNIDA ENTRE LA PARED INFERIOR (24) Y LA PARED CILINDRICA LATERAL (21) Y PROVISTO DE UN DIAMETRO EXTERIOR LIGERAMENTE PEQUEÑO AL DIAMETRO INTERNO DEL EXTREMO ABIERTO, Y UNA PARTE PLANA (27) UNIDA A LA PARTE DE RECESO (26) Y SIRVEN COMO UNA SUPERFICIE EXTREMA DE LA PARED INFERIOR (24). LA PARTE PLANA (27) SE ADAPTA PARA ACOPLARSE CON LA SUPERFICIE EXTREMA DEL EXTREMO ABIERTO DE UNA CARCASA ENTREETAPAS ADYACENTE . LA PARTE PLANA (27) TIENE UN DIAMETRO EXTERIOR LIGERAMENTE MAYOR QUE EL DIAMETRO EXTERIOR DEL EXTREMO ABIERTO. LA CARCASA INCLUYE TAMBIEN UNA PARTE DE RECESO (26) UNIDA A LA PARTE CILINDRICA (25) Y MENOR EN DIAMETRO QUE LA PARTE CILINDRICA. LA PARTE DE RECESO PROPORCIONA UN ESPACIO PARA INSTALAR UNA JUNTA TORICA (31) EN LA MISMA.
