Abstract
A pressure tank includes a hollow container which has an outlet for discharging fluid therefrom. The outlet is provided with a valve seat, for receiving a valve member which is slidably mounted in the container above the valve seat for respective movement between an open position, so that fluid in the container can flow therefrom through the outlet and a closed position so as to prevent discharging of fluid out of the container. A flexible partition is provided in the container, subdividing the interior thereof into a gas-containing compartment and into a liquid-containing compartment. The partition is displaceable on expansion of gas in the gas compartment, into an extended position immediately adjacent the outlet. An element is connected to the valve member, which element cooperates with the partition in the extended position of the same so as to prevent premature movement of the valve member into the closed position until the container is empty.
