SANITARY-ENGINEERING INSTALLATION THAT OPERATES AT HIGHER PRESSURE Russian patent published in 2010 - IPC E03D3/00 

FIELD: personal use articles.

SUBSTANCE: sanitary-engineering device works under pressure and comprises, without limitation, a toilet bowl, and also flush tank comprising channels of water letting in and out under pressure and discharge reservoir for water and air accumulation under higher pressure, which represents a tight thin-walled vessel, shell of which is arranged in the form of two convex surfaces, which are joined to each other by means of cylindrical part. Besides convex parts of discharge reservoir shell are manufactured in the form of two halves of triaxial ellipsoid cut along plane of section of maximum area, on every of which there is either a water letting-in or letting-out channel mounted. Ellipsoid is oriented relative to toilet bowl so that plane of ellipsoid symmetry passing through its longest and shortest axes matches vertical plane of toilet symmetry. Size of ellipsoid axis of medium length does not exceed maximum width of upper end section of toilet bowl.

EFFECT: water saving, increased reliability and reduction of device cost.
