Abstract

Un attuatore pneumatico, rotativo, a doppia cremagliera con ammortizzatore in contropressione. L'attuatore comprende due cremagliere mobili alternativamente in corrispondenti cilindri pneumatici, che si impegnano sui lati opposti del pignone di un albero di uscita. Ciascuna cremagliera alle sue estremità è provvista di pistoni scorrevoli in una camera di comando rispettivamente in una camera di contropressione che vengono messe in comunicazione attraverso un condotto assiale nella cremagliera, provvisto di una valvola di ritegno azionata da un organo di contrasto. La camera di contropressione comunica a sua volta con l'esterno attraverso un orifizio regolabile; l'organo di contrasto penetra in detto condotto per aprire in modo controllato la valvola di ritegno immediatamente prima che la cremagliera giunga al termine della sua corsa.
