Abstract
UN APARATO (1) PARA EL SUMINISTRO DE FORMULACIONES BASADAS EN AGUA TALES COMO UN PULVERIZADOR DE AEROSOL QUE PROPORCIONA CANTIDADES DE LIQUIDO Y AIRE A PRESURIZAR POR LA ACCION DE UNA BOMBA EN CAMARAS SEPARADAS (61,59) DEFINIDAS POR CILINDROS SOLIDARIOS (14,10). EL LIQUIDO SE DISTRIBUYE A TRAVES DE UN ORIFICO (69) A TRAVES DE UN CANAL DE DISTRIBUCION (67) QUE EN UN ASPECTO DE LA INVENCION SE PURGA DURANTE UNA PARTE TERMINAL DE LA CARRERA DE ACTUACION AL LIBERAR EL AIRE A TRAVES DEL CANAL DE DISTRIBUCION. EN UN SEGUNDO ASPECTO DE LA INVENCION SE MEZCLAN AIRE Y LIQUIDO DURANTE LA CARRERA DE ACTUACION PARA DISTRIBUIRLOS DE FORMA CONJUNTA Y DURANTE UNA CARRERA DE RETORNO EL AIRE ES ABSORBIDO A TRAVES DEL CANAL DE DISTRIBUCION PARA RETIRAR EL LIQUIDO RESIDUAL. LA ACCION DE LIMPIEZA POR CHORRO DE AIRE PREVIENE LA FORMACION DE DEPOSITOS EN EL CANAL DE DISTRIBUCION Y EN EL ORIFICIO.
