Device (100) for preserving and serving, from a bottle, by-the-glass liquid that can be affected by oxygen such as wine, by pumping pressurized inert gas in a bottle (40′). The device comprises a coupling portion (10) adapted to couple with a pressurized gas supply, a central body (20), and a fastening portion (30) to the bottle (40′), in particular, to a bottle neck (40). The central body (20) provides an inlet duct (21) of the pressurized gas, associated with an inlet valve (24), and a delivery duct (22) of the liquid, associated with a delivery valve (25), which draws the liquid from the bottle (40′) and brings it to a delivery mouth (23). In particular at least one among the inlet valve (24) and the delivery valve (25) is a pilot valve, which is piloted by the pressure of the inert gas. Furthermore, a pilot channel (26), (29) is provided communicating with a pilot port (27), (28) present in the coupling portion (10) and communicating with the pilot valve.

1. Apparatus for preserving and serving from a bottle by-the-glass liquid that can be affected by oxygen, in particular wine, by pumping pressurized inert gas into said bottle, said bottle having a neck with an inlet mouth, said device comprising: a coupling portion adapted to couple with a pressurized gas supply,a central body, anda fastening portion to said bottle adapted to engage with said inlet mouth, said body having: a pressurized gas inlet duct, ending in said bottle, communicating with an inlet port present on said coupling portion, anda liquid delivery duct, which draws the liquid from the bottle and brings it to a delivery mouth,wherein to said inlet duct an inlet valve is associated, adapted to open said inlet duct when delivery of liquid is requested and to stop said inlet duct and to prevent the inert gas flow when delivery of liquid is not requested, and whereinto said delivery duct a delivery valve is associated, adapted to open said delivery duct when delivery of liquid is requested and to stop said delivery duct and to prevent the liquid to exit from the bottle when delivery of liquid is not requested,wherein at least one among said inlet valve and said delivery valve is a pilot valve that is piloted by the pressure of said inert gas, and whereina pilot channel is provided communicating with a pilot port present in said coupling portion and communicating with said pilot valve. 2. A device, according to claim 1, wherein said valve piloted by the pressure of said inert gas is said inlet valve. 3. A device, according to claim 1, wherein said valve piloted by the pressure of said inert gas is said delivery valve. 4. A device, according to claim 1, wherein both said inlet valve and said delivery valve are valves piloted by the pressure of the inert gas, having each a respective pilot channel communicating with a respective pilot mouth. 5. A device, according to claim 1, wherein said pilot valve comprises: a first chamber connected to said pilot duct from which the gas is inserted;a second chamber connected to said inlet duct and/or with said delivery duct;a membrane arranged between said first and second chamber;a stopper arranged in said second chamber and integral to said membrane,such that said membrane deforms by the pressure difference between said first and second chamber and moves said stopper from a first position that opens said inlet duct and/or said delivery duct, to a second position that blocks said inlet duct and/or said delivery duct. 6. A device, according to claim 5, wherein said central body is a box-like body with a housing having a shoulder, said first and second chamber being obtained arranging said membrane on said shoulder, said first chamber being obtained from a plug that tightly engages in said housing and has a recess and an edge, such that in closed position of said plug in said housing said edge presses said membrane against said shoulder, and said first chamber is formed by said recess, whereas the second chamber is formed by the other part of said housing beyond said membrane. 7. A device, according to claim 6, wherein said housing from the side of said second chamber has a hole where said stopper engages, beyond said hole a pass being provided that represents a portion of said inlet duct and/or said delivery duct that said stopper selectively opens or blocks. 8. A device, according to claim 1, wherein said coupling portion comprises a flange that slidingly engages with a guide that is made in said pressurized gas supply such that said flange aligns with said inlet duct to enable said gas to pass. 9. A device, according to claim 1, where in said coupling portion a recess is made having a plurality of channels that in use connect the inlet port of said inlet duct and said pilot ducts.
