ABSTRACT:
A projection television display tube comprising an evacuated envelope (1) having a display window (4) which on its inside has a display screen (5) and in front of which on its outside a transparent second window (6) is provided, a cooling liquid (16) flowing through a space (7) between the display window and the second window from at least one inlet aperture (19) to at least one outlet aperture (17), said space communicating with an expansion vessel. The expansion vessel in the operating condition of the tube is present on the top side of the space and is a gas-filled rigid chamber (20), providing effective compensation for the thermal expansion of the cooling liquid (16) without the flow of cooling liquid being obstructed.
