Title (EN) DAMPENED TELESCOPIC SPRINKLER SYSTEM
(FR) SYSTEME D'EXTINCTEUR TELESCOPIQUE A AMORTISSEMENT
Abstract:
(EN) A telescopic high pressure sprinkler system (10) includes a plurality of gaskets (18) forming sliding seals between the piston (21) and the outer conduit (11), and bleeder holes (57). The volume between the gaskets (18) and the piston (21) and the outer conduit (11) forms a fluid chamber (49) that is compressed as the piston (21) is deployed so as to dampen the acceleration of Sprinkler deployment. The bleeder holes (57) regulate the compression of the fluid chamber (49). A cushion gasket (17) stops the piston (21) at full compression of the fluid chamber (49).
(FR) La présente invention concerne un système d'extincteur télescopique à haute pression (10) comprenant plusieurs joints statiques (18) formant des joints d'étanchéité coulissants entre le piston (21) et le conduit extérieur (11), et des orifices de purge (57). Le volume compris entre les joints statiques (18), le piston (21) et le conduit extérieur (11) forme une chambre à fluide hydraulique (49) qui est comprimée lorsque le piston (21) est déployé de façon qu'il amortit l'accélération du déploiement de l'extincteur. Les orifices de purge (57) permettent de réguler la compression de la chambre à fluide hydraulique (49). Un joint statique (17) amortisseur arrête le piston (21) lorsque la chambre à fluide hydraulique (49) est arrivée à une compression complète.
