Water installation arrangement with cylinder unit

摘要

In the bore of the cylinder unit (25) there is a free-floating piston (33) which moves axially in water- and gas-tight manner, dividing the cylinder space into two chambers. In the first chamber there is a pressure storage device, coacting with the piston. The main line section (18) has one end (19) supplied with water from a water installation section. The other end (21) of the main line section feeds the water supply into a further section of the water installation. There is a secondary line section (22), branching from the main line section and opening into the second cylinder chamber. Pref. the pressure storage is formed by a volume of air enclosed in the first cylinder chamber.
