FIELD: mechanical engineering.
SUBSTANCE: invention relates to water reservoirs, specifically to automatic machines for selling water by automatically controlled supply of water from the water reservoir to the water filling chamber through its (water reservoir) bottom branch pipe by means of a centrifugal pump with a "wet" rotor located in the hydraulic lock of the corresponding supply pipeline. Technical problem consists in the need to damp the water vortex formed in the water reservoir during operation of the centrifugal pump, for which a corresponding silencer is required. Blade silencer of water vortex for bottom branch pipe of water reservoir of aqua vending apparatus comprises disc 1, horizontal in working position of silencer, with four L-shaped blades 2-5 on one side of disc, so that these blades are connected to each other with formation of L-shaped crosspiece of silencer symmetrical relative to disc axis . Each blade is an L-shaped plate including horizontal and vertical elements. Horizontal elements 6, 8, 10 and 12 of these four plates together form a four-blade horizontal shelf in the working position of the silencer, on which disk 1 is located and which is permanently attached to disk 1. Vertical elements 7, 9, 11 and 13 of these four plates together form a four-blade vertical leg in the silencer working position, made with possibility of this leg location in the bottom branch pipe 15 in the silencer working position relative to this branch pipe.
EFFECT: damping of said water vortex, as a result of which the possibility of air passage into the bottom branch pipe of the water reservoir and into the centrifugal pump of the hydraulic system during its operation is excluded and, as a result, increased reliability of the hydraulic system and increased service life.
