Abstract

UN ELEMENTO DE MEDICION DE FLUIDOS (1) UTIL PARA UN SISTEMA DE SUMINISTRO IMPLANTABLE (1'') QUE SE ENCUENTRA ACOPLADO ENTRE UNA FUENTE DE FLUIDOS A PRESION (100'') Y UN CONDUCTO DE SALIDA (106) PARA PROPORCIONAR IMPULSOS DE FLUJO DISCRETOS A UNA VELOCIDAD PREDETERMINADA. EL ELEMENTO DE MEDICION (1) CONSISTE EN UN PRIMER MIEMBRO MOVIL (3) ENCERRADO DENTRO DE UN ALOJAMIENTO (2) Y UN SEGUNDO MIEMBRO MOVIL (4) RETENIDO EN UNA RANURA (12) POR EL PRIMERO. EL POSICIONAMIENTO ALTERNO DEL PRIMER MIEMBRO LLENA Y VACIA SIMULTANEAMENTE UNA CAVIDAD (16) EN LA QUE RESIDE EL SEGUNDO, DESCARGANDO EL FLUIDO A TRAVES DEL CONDUCTO. EL PRIMER MIEMBRO MOVIL PUEDE SER UNA CORREDERA PLANA (3), UN CILINDRO CAPAZ DE TRASLADARSE AXIALMENTE (131) O UN CILINDRO ROTATIVO (144). EL SEGUNDO MIEMBRO MOVIL PUEDE SER UNA LANZADERA PLANA (4), UNA BARRA DESLIZANTE (130) O UN DIAFRAGMA (161).
