Abstract
Abstract An apparatus (10) for the aeration of water, beverages and liquids in general, comprises a tank (11) provided with one or more inlets (17) connected to a supply (A) of the liquid to be aerated, one or more inlets (19) connected to a source (B) of gas under pressure, and one or more outlets (21) for removal of the aerated liquid, and also comprises valves (18, 20, 22) which regulate the flow of fluid along each inlet (17, 19) and each outlet (21); at least one rotating member (24) provided with agitating means is housed in a freely rotatable manner inside the tank (11) and is arranged opposite the gas inlet so as to be actuated by the gas introduced into the tank (11) and so as to agitate the liquid to be aerated which has been introduced into the tank (11). This apparatus is simple, reliable, low-cost and requires little maintenance.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
149 words
Apparatus (10, 30) for the aeration of water,
beverages and liquids in general, comprising a tank (11)
provided with one or more inlets (17) connected to a
supply (A) of the liquid to be aerated, one or more
inlets (19) connected to a source (B) of gas under
pressure, and one or more outlets (21) for removal of the
aerated liquid, and comprising valve means (18, 20, 22)
which regulate the flow of fluid along each inlet (17,
19) and each outlet (21), characterized in that it
comprises at least one rotating member (24) which is
provided with agitating means and is housed in a freely
rotatable manner inside the tank (11) and arranged
opposite the gas inlet so as to be actuated by the gas
introduced into the tank (11) and so as to agitate the
liquid to be aerated which has been introduced into the
tank (11).
Claim 2
Dependent Claim
30 words
Apparatus according to Claim 1, in which said
rotating member consists of an impeller (24) integral
with a shaft (25) supported in a freely rotatable manner
inside the tank (11).
Claim 3
Dependent Claim
45 words
Apparatus according to Claim 1 or 2, in which
the rotating member (24) is arranged on a central axis
(Y) of the tank (11) and a gas inlet pipe (19) which
extends inside the tank (11) as far as the rotating
member (24) is provided.
Claim 4
Dependent Claim
38 words
Apparatus according to any one of the
preceding claims, in which a plurality of said rotating
members (24) coupled in rotation with one another are
provided, at least one of said members being arranged
opposite the gas inlet.
Claim 5
Dependent Claim
23 words
Apparatus according to any one of the
preceding claims, comprising means (31, 32, 33) for
compensation of the pressure inside the tank (11).
Claim 6
Dependent Claim
94 words
Apparatus according to Claim 5, in which said
compensation means comprise a member (31) which is
movable inside the tank (11) and which divides the tank
into a first chamber (32) into which the fluid under
pressure is introduced and a second chamber (36) inside
which aeration of the liquid occurs, the movable member
(31) being displaced inside the tank depending on the
difference in pressure between the first chamber (32) and
the second chamber (36) so as to vary the volume of the
second chamber (36) and correspondingly maintain the same
pressure therein.
Claim 7
Dependent Claim
17 words
Apparatus according to Claim 6, in which said
movable member consists of a resiliently deformable
membrane (31).
Claim 8
Dependent Claim
19 words
Apparatus according to Claim 7, in which the
edge of said membrane (31) is fixed to the tank (11).
Claim 9
Dependent Claim
50 words
Apparatus according to any one of the
preceding claims, in which the valve means (18, 20) which
regulate the entry of the liquid and the gas into the
tank (11) allow, during the aeration operation, first
entry of the liquid and then entry of the gas into the
tank (11).
