Abstract

UN ROCIADOR GIRATORIO INCLUYE UN ROTOR MONTADO DE MODO GIRATORIO CON RESPECTO A SU BOQUILLA Y UN DISPOSITIVO DE RETARDO QUE TIENE UNA PRIMERA SUPERFICIE QUE PUEDE GIRAR CON EL ROTOR, UNA SEGUNDA SUPERFICIE NO GIRATORIA RESPECTO DE LA BOQUILLA, Y UN LIQUIDO VISCOSO ENTRE LAS DOS SUPERFICIES. LA PRIMERA SUPERFICIE DEL DISPOSITIVO DE RETARDO ES UNA CAVIDAD FORMADA EN EL ROTOR, Y LA SEGUNDA SUPERFICIE DEL DISPOSITIVO DE RETARDO ESTA EN UNA ESPIGA MONTADA SIN GIRO ALGUNO RESPECTO DE LA BOQUILLA Y DISPUESTA DENTRO DE LA CAVIDAD. EL ROTOR INCLUYE ADEMAS UNA CUBIERTA QUE CIERRA LA CAVIDAD Y ESTA FORMADA CON UNA ABERTURA PARA RECIBIR LA ESPIGA, Y UN SELLO SOSTENIDO POR LA CUBIERTA Y QUE INCLUYE UN SUPERFICIE DE SELLADO ANULAR EN CONTACTO CON LA ESPIGA PARA SELLAR LA CAVIDAD, ESTANDO SITUADA LA SUPERFICIE ANULAR DEL SELLO DE MODO QUE SE SUMERJA CONTINUAMENTE EN EL LIQUIDO VISCOSO EN LA CAVIDAD.A ROTATING SPRINKLER INCLUDES A ROTALLY MOUNTED ROTOR WITH RESPECT TO ITS NOZZLE AND A DELAY DEVICE THAT HAS A FIRST SURFACE THAT CAN ROTATE WITH THE ROTOR, A SECOND NON-ROTATING SURFACE WITH RESPECT TO THE NOZZLE, AND A LIQUID SURFACE. . THE FIRST SURFACE OF THE DELAY DEVICE IS A CAVITY FORMED IN THE ROTOR, AND THE SECOND SURFACE OF THE DELAY DEVICE IS ON A MOUNTED TAP WITHOUT ROTATION IN RESPECT OF THE NOZZLE AND ARRANGED WITHIN THE CAVITY. THE ROTOR FURTHER INCLUDES A DECK THAT CLOSES THE CAVITY AND IS FORMED WITH AN OPENING TO RECEIVE THE TIP, AND A SEAL SUSTAINED BY THE DECK AND WHICH INCLUDES A SEALING SURFACE CANCELLATE IN CONTACT WITH THE TIP TO SEAL THE CAVITY, BEING SITUATED CANCEL THE SEAL SO THAT IT IS CONTINUOUSLY IMMERSED IN THE VISCOSE LIQUID IN THE CAVITY.
