Abstract

Mejoras introducidas en la patente de invención 9401231, por "bomba dosificadora de aceite para motores de dos tiempos''. Consisten en establecer en el cuerpo general (1) de la bomba una entrada (2) y dos salidas (3-3"''), con las que colabora el conducto único (11) establecido en el distribuidor, que comunica secuencialmente con aquellas, contando dicho distribuidor en su base con una doble leva (14-15), plana, semicircunferencial y con dos sectores de diferente anchura, mientras que en el clásico eje (16) de levas se establecen tres levas, una central (17), de admisión, y dos extremas (18) y (19), de impulsión respectivamente hacia las dos salidas (3-3"''), siendo el sector (14) de la primera leva susceptible de actuar sobre las dos levas de impulsión (18) y (19), obviamente primero sobre una de ellas y después sobre la otra, mientras que el sector (15) más estrecho está capacitado para actuar exclusivamente sobre una de estas levas de impulsión (18) y sobre la leva de admisión (17).
