Abstract

UN PISTON EN FORMA DE SETA 10 ES CONDUCIDO DENTRO DE SU CORRESPONDIENTE CILINDRO 20 MEDIANTE UNA PARTE CONDUCTORA ANULAR 70 QUE SE EXTIENDA ALREDEDOR DE SU VASTA. LA PARTE CONDUCTORA FORMA "EL ROTOR" DE UN MOTOR ELECTRICO LINEAL, EL "ESTATOR" ESTA PROVISTO DE UN CILINDRO. LOS EXTREMOS DEL PISTON ESTAN EXPUESTOS A UNAS PRESIONES P1,P2 DONDE P1 ES MAYOR QUE P2. DURANTE EL MOVIMIENTO DEL MIEMBRO CONDUCTOR DEL PISTON CONTRA EL RESORTE 40 EL FLUJO DE FLUIDO A TRAVES DEL CANAL 76 EL CUAL CONTIENE UNA VALVULA DE UNA VIA 60 DONDE SE GENERA UNA SOBREPRESION EN LA CAMARA ENTRE LOS SELLOS 30, 32, 34, PREVINIENDO LA SALIDA DE FLUIDO A TRAVES DEL SELLO 30. LA FIGURA 2 MUESTRA UNA MODIFICACION EN LA QUE EL PISTON 110 TIENE UN POZO CENTRAL 114 QUE CONTIENE UN EMBOLO 180 INCLINADO POR UN DIAFRAGMA 140. AQUI LA SOBREPRESION SE GENERA EN EL POZO Y UN CANAL 116 SE EXPONE A UNA SOBREPRESION EN EL SELLO 131 PARA PREVENIR EL FILTRADO ALREDEDOR DEL PISTON.
