Abstract

L'invenzione concerne un cilindro maestro comprendente un corpo (12) provvisto di un'alesatura (14) nella quale scorre a tenuta almeno un pistone (16, 18), spostabile fra una posizione di riposo ed almeno una posizione di lavoro e definente almeno una camera di pressione (20, 22) connessa ad un circuito fluidico di utilizzazione. Il pistone (18) presenta una gola periferica (44). Secondo l'invenzione, un dito (42) azionato da un mezzo esterno (46) può penetrare nella gola (44) per bloccare il pistone in una delle sue posizioni.
