<p>The device (1) has at least one cylinder (35, 36) housed inside a pressure chamber (40) enclosed by a casing (30). A sliding plate (10) can be moved transverse to the flow direction in order to block the flow. The plate is connected via a piston rod (25, 26) to a piston (27, 28) driven by a pressurised medium introduced via at least one closure valve (45) from a pressurised vessel to a cylinder work region (46, 47).</p> |
