Abstract
The invention relates to a pressurized container valve which has a simple structure, is easy to use and is functionally reliable and which is used, in particular, in a compressed air respirator which is used as rescue breathing apparatus. Said valve comprises a supply connection (2) and a discharge housing (3) which are connected together on the front sides such that they can be rotated or can be displaced in a linear manner against each other, by means of first and second planar ceramic valve discs acting as blocking elements (8, 11). A supply and/or discharge opening (9, 12) respectively provided in the first and/or second valve disc is aligned with the supply channel (10) and/or the discharge channel (15) in the supply connection (2) and/or in the discharge housing. The valve can be opened or sealingly closed in a simple manner by rotating the discharge housing about the longitudinal axis thereof or displacing the discharge housing in a linear manner in relation to the supply connection. Said pressurized container which is connected to the valve can be filled according to the same principle via the filling opening (13).
