<p>The invention relates to a bleed valve for extracting condensed fuel gases from a reservoir, the bleed valve having a valve housing, a bleed opening provided in this housing, a bleed line, formed in the valve housing and leading from the reservoir to the bleed opening, a first moving valve member for opening and closing the bleed line, and a safety valve, likewise arranged in the valve housing, which automatically at least partially blocks the bleed line if the fuel gas exceeds a specific bleeding rate. In order to allow rapid emptying of the reservoir, bypassing the safety valve, an additional emptying nozzle is provided arranged on the valve housing, which is normally closed by a second moving valve member, and the second valve member has a means of operation engaging on the safety valve which renders the safety valve inoperative when the second valve member moves to its open position, such that fuel gas can emerge from the emptying nozzle at a high bleeding rate. <IMAGE></p> |
