Abstract

L'invention vise à produire de l'eau sanitaire à partir d'eau salée ou d'eau polluée et repose sur un coffre à eau (1) sur lequel est monté un cylindre (2) doté d'un piston de levée (3). Une soupape de refoulement (12) et une soupape d'eau de rinçage (17) sont montées sur le coffre à eau (1). La soupape de chambre de piston (11) en face de laquelle est monté le réservoir d'alimentation (4) est placée au-dessus de la chambre de piston (10). Le piston de levée (3) est déplacé par exemple par la tige de piston (5). Une dépression se crée dans le coffre à eau (1), sous l'effet de la remise en place du piston de levée (3) depuis le point le plus bas, lorsque les soupapes sont fermées. De l'eau brute est injectée par le piston de levée (3) avant la fin de la phase de retour du piston. L'eau brute évaporée est évacuée par la soupape de refoulement (12) et traitée de manière plus poussée dans le mouvement en avant du piston de levée (3).
