Abstract: The present invention relates to an installation for automatically purifying one or more enclosures located in one or more premises, such as toilets, comprising:a supply module comprising a control panel and a reservoir of liquid purifying product;at least one module for spraying the purifying product, comprising an electrovalve and a spray;each spray module being connected to the supply module via a single pipe;characterized in that it comprises means for placing said product under pressure, solely in said pipe, the pressure being substantially greater than atmospheric pressure.

Abstract: This invention relates to a toilet system of the type with direct evacuation and rinsing without flushing effect nor siphon, constituted by a bowl of generally truncated form comprising at the level of its small base, in lower position, a trap controlled by a pneumatic jack, for intermittent communication with an evacuation conduit, and the bowl comprises at least one nozzle for projecting rinsing and evacuation water coming from a pressurizing chamber, characterized in that said system is connected to a source of energy constituted by a source of compressed air communicating on the one hand with the pressurizing chamber to ensure high pressure supply of the rinsing and evacuation nozzles and, on the other hand, with the pneumatic jack for maneuvering the trap, such communication being ensured by a pneumatic slide valve adapted to regulate and control the evacuation cycle comprising the synchronized phases, firstly, of opening of the trap and of projection of pressurized water and, secondly of closure of the
