Abstract

LA BOMBA INCLUYE UN CUERPO DISTRIBUIDOR (7) EN EL QUE ESTA REALIZADA UNA CAMARA DE BOMBEO (6) CUYO VOLUMEN ES VARIABLE EN VIRTUD DE QUE TAL DISTRIBUIDOR (7) ES DESPLAZABLE AXIALMENTE, PRODUCIENDOSE ESA VARIACION COMO CONSECUENCIA DE QUE EN EL INTERIOR DE LA CAMARA (6) EXISTE UN PISTON ESTACIONARIO (5) EMPUJADO CONTRA UNA TAPA (4) MEDIANTE UN MUELLE (8) QUE A SU VEZ EMPUJA EN SENTIDO CONTRARIO AL PROPIO DISTRIBUIDOR (7). DICHO CUERPO DEL DISTRIBUIDOR (7), ADEMAS DEL DESPLAZAMIENTO AXIAL ALTERNATIVO, ESTA SOMETIDO A UN MOVIMIENTO GIRATORIO PARA PERMITIR LA COMUNICACION ALTERNATIVA DE LA ENTRADA Y SALIDA CON LA PROPIA CAMARA DE BOMBEO (6), PRODUCIENDOSE EL MOVIMIENTO DE GIRO POR MEDIO DE UN SINFIN QUE ATACA A UN DENTADO (9) SOLIDARIO DEL PROPIO DISTRIBUIDOR (7), MIENTRAS QUE EL DESPLAZAMIENTO AXIAL SE REALIZA POR CONTACTO DE UNA LEVA (11) CONFORMADA EN LA PARTE INFERIOR DEL DISTRIBUIDOR (7) QUE ALTERNATIVAMENTE Y CADA MEDIA VUELTA CONTACTA CONTRA LA LEVA (13) O LA LEVA (12) CONFORMADAS EN UN EJE (14) PERPENDICULAR AL EJE AXIAL DEL DISTRIBUIDOR (7). LA BOMBA TIENE POR FINALIDAD EL DESPLAZAR UN CAUDAL DE ACEITE PARA LA LUBRICACION DE UN MOTOR DE DOS TIEMPOS, EN FUNCION DEL REGIMEN DE GIRO DE ESTE Y DEL GRADO DE ESTRANGULAMIENTO DE LA VALVULA DE CONTROL DE GASES DE LA ADMISION DEL MOTOR.THE PUMP INCLUDES A DISTRIBUTOR BODY (7) IN WHICH A PUMPING CHAMBER IS MADE (6) WHOSE VOLUME IS VARIABLE VIRTUE THAT SUCH DISTRIBUTOR (7) IS AXIALLY DISPLACABLE, PRODUCING THAT VARIATION AS A RESULT OF THE INTERVAL OF THE CHAMBER (6) THERE IS A STATIONARY PISTON (5) PUSHED AGAINST A COVER (4) THROUGH A SPRING (8) WHICH IN turn PUSHES IN THE DIRECTION OF THE OWN DISTRIBUTOR (7). SAID BODY OF THE DISTRIBUTOR (7), IN ADDITION TO THE ALTERNATIVE AXIAL DISPLACEMENT, IS SUBJECTED TO A ROTATING MOVEMENT TO ALLOW THE ALTERNATIVE COMMUNICATION OF THE ENTRY AND EXIT WITH THE OWN PUMPING CHAMBER (6), PRODUCING THE MOVIMO DEL PORTO THAT ATTACKS A TOOTHED (9) SOLIDARITY OF THE OWN DEALER (7), WHILE THE AXIAL DISPLACEMENT IS MADE BY CONTACT OF A CAM (11) CONFORMED IN THE BOTTOM OF THE DEALER (7) THAT ALTERNATIVELY AND EVERY HALF TURN CONTACT THE CAM (13) OR CAM (12) CONFORMED TO A SHAFT (14) PERPENDICULAR TO THE AXIAL SHAFT OF THE DISTRIBUTOR (7). PURPOSE OF THE PUMP IS TO DISPLACE AN OIL FLOW FOR THE LUBRICATION OF A TWO-STROKE ENGINE, DEPENDING ON THE EAST TURNING REGIME AND THE STRAINING DEGREE OF THE ENGINE INTAKE GAS CONTROL VALVE.
