Abstract

UN MOTOR HIDRAULICO DE PISTON AXIAL O BOMBA (8) DEL TIPO EN EL QUE UN ROTOR (10) TIENE UNA PLURALIDAD DE NUMERO IMPAR DE ABERTURAS DE CILINDRO (30) CON LAS QUE LAS ABERTURAS ARQUEADAS (40, 42) DE UNA PLACA DE ABERTURA (36) ENTRAN EN CONTACTO SUCESIVAMENTE. LA PLACA DE ABERTURA (36) ESTA PROVISTA CON ABERTURAS DE INTERCAMBIO DE FLUIDO (44, 46) A TRAVES DE LAS CUALES COMUNICAN UNOS CILINDROS (16) CON UN SISTEMA DE CAPACITANCIA HIDRAULICA (81, 82, 84, 86, 93). EL SISTEMA DE CAPACITANCIA (81, 82, 84, 86, 93) MANDA EL FLUIDO A CADA CILINDRO (16) DEL ROTOR (10) A TRAVES DE UNA ABERTURA DE INTERCAMBIO (44) DESPUES DE QUE LA ABERTURA DE CILINDRO ASOCIADA (30) NO ESTE EN CONTACTO CON UNA ABERTURA ARQUEADA (40) PERO ANTES DE QUE EL PISTON ASOCIADO (14) HAYA ALCANZADO SU POSICION DE CENTRO MUERTO INFERIOR (72), Y RECIBE EL FLUIDO DESDE CADA CILINDRO A TRAVES DE UNA ABERTURA DE INTERCAMBIO (46) DESPUES DE QUE EL PISTON ASOCIADO HAYA COMENZADO SU GOLPE DE COMPRESION PERO ANTES DE QUE LA ABERTURA DE CILINDRO HAYA EMPEZADO A ESTAR EN CONTACTO CON UNA SEGUNDA ABERTURA ARQUEADA (42). LA IMPULSION DEL FLUIDO A CADA CILINDRO ELIMINA LOS EFECTOS DE CAVITACION QUE DE OTRA FORMA RESULTARAN DEL TENER UNA ZONA DE DESCOMPRESION DEMASIADO GRANDE (68, 67), MIENTRAS QUE LA RECEPCION DE FLUIDO DESDE CADA CILINDRO IMPIDE LA PRESURIZACION EXCESIVA QUE DE OTRA FORMA RESULTARA DEL TENER UNA ZONA DE PRECOMPRESION DEMASIADO GRANDE (67). LA INVENCION PERMITE DE ESTE MODO EL USO DE ABERTURAS ARQUEADAS (40, 42) QUE SOBREMANTIENEN LOS ALCANCES ANGULARES MAS LIMITADOS REQUERIDOS PARA PROPORCIONAR UNA BOMBA O MOTOR QUE FUNCIONA CON UN NUMERO CONSTANTE DE CILINDROS DE GRAN PRESION Y, CONSECUENTEMENTE, CON UNA FUERZA DE AGARRE CONSTANTE ENTRE EL ROTOR (10) Y LA ABERTURA DE PLACA (36).
