Abstract

Un attuatore lineare comprendente un cilindro pneumatico provvisto di mezzi di arresto meccanici ed un ammortizzatore pneumatico portati da un'unità telescopica di supporto scorrevole internamente al cilindro, regolabile in posizione per variare la corsa del pistone; l'unità di supporto dell'ammortizzatore pneumatico può essere regolata in posizione tramite mezzi a vite azionabili manualmente. Un condotto estensibile nell'unità telescopica di supporto collega la camera del cilindro con una valvola di sfogo dell'aria, prevista in una testata estrema di chiusura dell'attuatore.A linear actuator comprising a pneumatic cylinder provided with mechanical stop means and a pneumatic shock absorber carried by a telescopic support unit sliding inside the cylinder, adjustable in position to vary the stroke of the piston; the shock absorber support unit can be adjusted in position by means of manually operated screw means. An extensible duct in the telescopic support unit connects the cylinder chamber with an air vent valve, provided in an extreme closing head of the actuator.
