Abstract

DISPOSITIVO DE INTERCEPCION DE UN FLUIDO.COMPRENDE UN CUERPO (2) SUBDIVIDIDO EN DOS PORCIONES: SUPERIOR (3) E INFERIOR (4), UNIDAS POR UN ELEMENTO TUBULAR MARCADO EN SU INTERIOR (5) CON UN CONDUCTO (6) POR EL QUE CORRE EL FLUIDO A CORTAR. LA PORCION (4) ESTA PREPARADA AXIALMENTE PARA DEFINIR UN ASIENTO CILINDRICO (8) POR EL QUE SE DESLIZA UN PISTON (9). EN LA PARTE DIRIGIDA HACIA (3), EL PISTON (9) PRESENTA UNA CABEZA (10) CON DIAMETRO REDUCIDO Y UNA ACANALADURA (11), LAS CUALES DEFINEN JUNTO CON (8) DOS CAMARAS ANULARES (13 Y 12). EL PISTON (9) PRESENTA UN VASTAGODE EXTREMO (15) POR LA PARTE OPUESTA A (10) QUE DEFINE CON LA PORCION (11) UN ESPACIO INTERMEDIO (16) QUE COMUNICA CON (6) A TRAVES DE UNA CAMARA ANULAR (17). POR LA PARTE OPUESTA A ESTA PRESENTA UNA CABEZA DE ALFILER (18) QUE CIERRA UNOS ORIFICIOS PASANTES (19) QUE PRESENTA (4). LAS CAMARAS (12 Y 13) A TRAVES DE CONDUCTOS (22 Y 23) A CAMARAS ESFERICAS (24, 25), QUE ALOJAN CADA UNA UN ELEMENTO (26, 27) EN FORMA DE FUNDA ESFERICA REALIZADA EN MATERIAL PIEZOELECTRICO.
