Abstract

EN UNA DISPOSICION DE LAS VALVULAS EN MOTORES DE IMPACTO NEUMATICO (10), EL ALOJAMIENTO (40) DE UNA VALVULA DE DISTRIBUCION TIENE FORMA DE TAZON DE PLASTICO (46) CON ALAS HACIA AFUERA EN LA APERTURA Y FONDO DEL MISMO. UNA VALVULA PLANA (50) SE MUEVE ENTRE EL FONDO DEL TAZON, QUE FORMA UN ASIENTO DE VALVULA (51) DEL ALOJAMIENTO DE LA VALVULA (40), Y UN MIEMBRO PARA CUBRIR EL TAZON (53), QUE FORMA EL OTRO ASENTAMIENTO DE VALVULA (52). LAS ALAS DEL TAZON, DEFINEN ENTRE ELLAS UNA HENDIDURA, QUE CONECTA CON UN CANAL DE SUMINISTRO (39) QUE SE PROPORCIONA EN EL MOTOR DE IMPACTO (10). ESTE CANAL SUMINISTRA AIRE COMPRIMIDO A LA VALVULA PLANA (50) MONTADA DENTRO DEL TAZON (46). LA PARED DEL TAZON SITUADA ENTRE LAS ALAS (47,48) INCLUYE APERTURAS LATERALES CALIBRADAS (57,58) QUE CONTROLAN EL SUMINISTRO DE AIRE COMPRIMIDO A LOS ASENTAMIENTOS DE VALVULA RESPECTIVOS (51,52) EN LAS PAREDES RESPECTIVAS DE LA VALVULA PLANA (50). ESTE SUMINISTRO DE AIRE ES ADAPTADO Y CALIBRADO.
