Abstract

Bomba de vacío que comprende un primer y un segundo cilindros ( 1, 2 ) del mismo diámetro ( D ) en los que un primero y segundo pistones respectivos ( 3, 4 ) de los cuales cada uno, está movido por una excéntrica ( 51, 52 ), delimitan un primero y un segundo volúmenes ( V1, V2 ) respectivos, estando provisto cada cilindro de una entrada ( 11, 21) dotada de una válvula anti-retorno de aspiración ( 13, 23 ) y de una salida ( 12, 22 ) dotada de una válvula anti-retorno de expulsión ( 14, 24 ), estando alineados los cilindros ( 1, 2 ) uno con otro y colocados simétricamente con respecto a un eje principal ( X ), caracterizado porque los pistones ( 3, 4 ) están animados simultáneamente de movimientos respectivos de aspiración ( MA1, MA2 ), simétricos con respecto al eje principal ( X ), y por los cuales los volúmenes primero y segundo ( V1, V2) crecen, y de movimientos de expulsión respectivos ( MR1, MR2 ), simétricos con respecto al eje principal ( X ), y por los cuales los volúmenes primero ysegundo ( V1, V2 ) disminuyen, y porque los movimientos de aspiración y de expulsión ( MA1, MA2, MR1, MR2 ) tienen una primera y una segunda duraciones respectivas ( t1, t2 ) de las cuales la primera ( t1 ) es superior a la segunda ( t2 ).
