Abstract: A fluid expansion valve with a main body and a method of its use. The main body has an internal fluid passage and an outlet connector. The outlet connector is suitable for delivering the expanded fluid and for connecting with a socket. The internal profile of the socket is suited for connection with the external profile of the outlet connect. The outlet connect has three connention sections of varying external diameters. The valve may be used to introduce a pressurized gas to a liquid or a beverage.

Abstract: The invention relates to a fluid expansion valve (50) comprising a main body (30) with an internal fluid passage (32, 32a, 32b) and an outlet connector (1). Said outlet connector is used to deliver the expanded fluid and is provided with an external profile that is suitable for the connection of a user socket having an internal profile that is adapted and/or complementary to the external profile of the connector. The outlet connector (1) comprises at least three cylindrical connection sections (P1 to P3) which are arranged in succession from the outlet end (11) of said outlet connector (1) to the connection end (10) of the outlet connector (1) on the body (30) of the expansion valve. Said connection sections (P1 to P3) are provided with increasing external diameters (D1 to D3). The invention also relates to the use of one such expansion valve to deliver a pressurised gas that is intended to pressurise a food drink, particularly beer or soft drinks.

Abstract: A fluid pressure-reducing unit or pressure-reducing valve allowing the pressure or flow rate of a fluid to be controlled or adjusted, including a main body within which at least one internal fluid passage is made between at least one fluid inlet orifice and at least one fluid outlet orifice, a part for controlling the fluid pressure and/or flow rate being arranged in or on at least part of the internal fluid passage, and at least one operator-operable rotary hand wheel part cooperating with the fluid pressure and/or flow rate control part, in response to the rotary hand wheel part being rotated, so as to control or adjust the pressure and/or the flow rate of the fluid flowing through the internal fluid passage and leaving via the fluid outlet orifice, wherein the rotary hand wheel parts can move in terms of rotation into a number of distinct angular positions, each angular position corresponding to a given fliud pressure or flow rate value, and the rotary hand wheel part having an angular travel less than 340

Abstract: The invention relates to an open-type protective cowling for a fluid container, particularly for a gas cylinder, made up of a cowling body (1) made of polymer comprising an insert (2) made of metal or metal alloy with a tapping (10). As a preference, the insert (2) is essentially in the shape of a ring with a tapped internal wall and the cowling body (1) is overmolded around the tapped insert (2). In addition, the insert (2) may have one or more recesses (7) and/or one or more strengtheners (6) on its external peripheral wall. Furthermore, the invention also relates to a gas cylinder equipped with such a protective cowling, and to the method for manufacturing such a protective cowling.
