Abstract

LA INVENCION TRATA DE UN CILINDRO DE INMERSION, EN EL QUE ESTA COLOCADO UN TUBO DE CONEXION DE SEÑALES 34 HIDRAULICO EN LA FUNDA DEL CILINDRO 30. EL TUBO DE CONEXION DE SEÑALES ESTA UNIDO AL INTERIOR DEL CILINDRO MEDIANTE UN TALADRO TRANSVERSAL 40. SOBRE EL LADO INTERNO DEL CILINDRO DEL TALADRO TRANSVERSAL 40 SE ENCUENTRA UN CANAL ANULAR 42 QUE SE LIMITA EN SUS FLANCOS ABIERTOS Y LATERALES Y EN SUS LADOS INFERIORES, MEDIANTE ANILLOS GUIA Y ANILLOS DE JUNTA 60, 62. EL ANILLO DE JUNTA 62 QUE LIMITA AL FLANCO LATERAL INFERIOR ESTA FORMADO A MODO DE ANILLO METALICO ABIERTO, EL CUAL ESTA SITUADO EN UN PINCHAZO 50 DEL CILINDRO, COLOCADO DETRAS Y EN FORMA ANULAR DE UN ANILLO DE JUNTA 63 DE ELASTOMERO. EL PISTON DE INMERSION 16 TIENE VARIOS TALADROS DE CONTROL 28 QUE PASAN A LA FUNDA DEL PISTON 22 A UNA DISTANCIA DEL EXTREMO INFERIOR DEL PISTON 26 QUE COMUNICA CON EL LADO INFERIOR DE LA CAMARA INTERNA DEL CILINDRO. AL SOBREPASAR EL CANAL ANULAR 42 SE DISPARA UN PROCEDIMIENTO INTERRUPTOR MEDIANTE LACONEXION DE SEÑALES .THE INVENTION IS ABOUT A DIPPING CYLINDER, IN WHICH A HYDRAULIC SIGNAL CONNECTION TUBE 34 IS PLACED IN THE COVER OF THE CYLINDER 30. THE SIGNAL CONNECTION TUBE IS ATTACHED TO THE INTERIOR OF THE CYLINDER BY A CROSS-CUTTING DRILL 40. ON THE SIDE INTERNAL OF THE CYLINDER OF THE TRANSVERSAL DRILL 40 IS AN ANNULAR CHANNEL 42 THAT IS LIMITED IN ITS OPEN AND SIDE FLANGES AND IN ITS LOWER SIDES, THROUGH GUIDE RINGS AND GASKET RINGS 60, 62. THE GASKET RING 62 THAT LIMITS THE LOWER SIDE FLANK IT IS FORMED AS AN OPEN METALLIC RING, WHICH IS LOCATED IN A PINCH 50 OF THE CYLINDER, PLACED BEHIND AND IN ANNULAR FORM OF A SEALING RING 63 OF ELASTOMER. DIP PISTON 16 HAS SEVERAL CONTROL HOLES 28 GOING TO PISTON CASE 22 AT A DISTANCE FROM THE BOTTOM END OF PISTON 26 COMMUNICATING WITH THE BOTTOM SIDE OF THE INTERNAL CHAMBER OF THE CYLINDER. ON EXCEEDING CANCEL 42, A SWITCHING PROCEDURE IS TRIPPED THROUGH THE SIGNAL CONNECTION.
