Abstract

Un cilindro maestro in tandem nel quale il pistone primario (3) ed il pistone secondario (4) sono distanziati uno dall'altro per mezzo di due molle (9, 10). Soltanto una (9) delle due molle è preventivamente sollecitata nella posizione di riposo dei pistoni. Le pressioni nelle camere primaria (6) e secondaria (7) divengono così rapidamente prossime una all'altra, senza che sia necessario montare le molle in una gabbia di lunghezza regolabile.
