Abstract: A valve which intended to control the flow of a fluid, for example a gas, comprises a valve body (50), an internal member for opening and shutting-off the passage of the gases, an operating handwheel (56) connected to the opening and shut-off member, and means limiting movement of the operating handwheel (56) and of the opening and shut-off member in the direction of opening of the valve. To avoid the valve jamming in the open position, said means limiting the movement of the operating member includes a stop (60) and of a mating stop (62), with frontal contact, arranged respectively on a rotary element and on the body of the valve (50) or vice versa. To ensure optimum contact between the stop (60) and the mating stop (62), the latter forms part of an element the angular position of which can be adjusted.

Abstract: The present invention relates to a visual valve indicator comprised of a handle assembly with peripheral sidewalls attached to a linear moving valve stem for opening and closing of the valve and a grommet stratified into one or more color bands attached to and surrounding the base of the valve stem. A breakaway portion of the grommet allows the handle assembly to close if the grommet is frozen, by breaking away from the grommet. A sawtooth-edged inner radius of the grommet allows the grommet to slide one direction when pushed down by the handle assembly, if the valve is worn.

Abstract: The tap intended for controlling the flow of a fluid, for example of a gas, comprises a tap body (34), an inner member (36) for opening and closing the passage of the gases, an outer rotary operating handwheel (42), a connector member (40) connecting the operating handwheel (42) to the closing member (36) and a stop mechanism limiting the movement of the operating handwheel (42) and of the opening and closing member (36) in the opening direction of the tap. In order to avoid the tap becoming jammed in the open position, the stop mechanism that limits the movement of the operating member comprises of an abutment (44) and a counterabutment (46) with frontal contact, which are arranged respectively on a rotary element and on the body (34) of the tap, or vice versa.

Abstract: The valve is intended to be opened at a predetermined temperature in order to release the pressurized fluid from the tank and its opening is triggered by melting of a meltable material. It comprises a body in the shape of a socket (10), the open end of which is exposed to the gas pressure and the bottom of which is closed except for a minuscule orifice (12). The side wall of the body (10) comprises at least one radial opening (14) and the body (10) is engaged, by its bottom, by sliding, in a cap (16) of complementary shape and is fastened thereto by means of the meltable material (18). The cap (16) comprises at least one access (20) to the atmosphere and, after melting of the meltable material (18), can be moved with respect to the body (10) until each access (20) communicates with a side opening (14) in the body (10).

Abstract: The shut-off device is intended for refillable gas cylinders. In order to be sure that only authorized persons can refill the cylinder, the filling device comprises a non-return valve element (16) which prevents filling and which can only be neutralized using a special magnet (18).

Abstract: A safety valve for a compressed gas tank in which the plug is made of meltable material and intended to melt at a pre-determined temperature in order to release the compressed gas from the tank. The safety valve is essentially characterized in that the meltable plug is subjected to the action of a differential action sliding piston intended for reducing at least some of the effect of the gas pressure on the meltable plug.

Abstract: A gas tap comprising an external operating element and a connecting stem for transmitting the movement of the operating element to the opening and closure member which is arranged in such a way as to be held against the sealing seat under the effect of the pressure of the gas. To make opening against the pressure of the gas easier, the operating element comprises a cylindrical sleeve which has a first screw thread that makes the sleeve move axially when the operating element is turned and a second screw thread of opposite hand to the first screw thread and with different screw pitch so as to alter the effect brought about by the first screw thread.

Abstract: The valve comprises an operating wheel connected by a connecting rod to an opening and closing member. The valve is sealed by a stuffening box fixed into the upper part of the body around the rod. The stuffening box has a polygonal head so that it can be screwed and unscrewed. However the head is not accessible using a conventional spanner so as to prevent a non-specialist form slackening of the stuffing box and avoid him risking an accident.

Abstract: The tap comprises an external operating element and a connecting stem for transmitting the movement of the operating element to the opening and closure member which is arranged in such a way as to be pressed against the sealing seat under the effect of the pressure of the gas. To make opening against the pressure of the gas easier, the connecting stem and/or the opening and closure member are designed in such a way that the opening of the tap comprises a first phase in which the opening and closure member pivots, followed by a movement of the axial translation.

Abstract: A trigger assembly comprising a handle through which there passes an axial duct and a spray mouth through which there passes an outlet passage. The posterior frontal face of the spray mouth and the anterior frontal face of the handle are surfaces with complimentary curvatures so that the spray mouth and the handle can pivot with respect to each other, against the action of elastic means, towards an open position in which the passage of the spray mouth and the duct of the handle are aligned with one another and, under the action of elastic means, towards the closed position in which the duct and the passage are not aligned with each other.

Abstract: The valve (30) comprises at least two lateral openings (34, 36) which can be shut off by a plug (40) provided with an axial orifice (48) for the passage of gas, which plug slides axially in the casing (32) between a position in which the openings (34, 36) are shut off under the influence of a spring (44) and an open position counter to the action of the spring (44) under the influence of the pressure of the filling gas, and a level valve (52) activated by a float (62) at the bottom of the casing (32).In order to prevent pressure from building up inside the casing (32) after closure, the latter is provided with escape orifices (50) which are associated with resilient opening means (64).

Abstract: The closure of the bottle is achieved with the aid of a cylindrical ring (20), the base of which is closed by a membrane (22). This ring (20) is put in place together with a filling adaptor which is screwed onto the neck of the bottle and which allows the ring (20) to be tightened after filling. A drawing-off adaptor is also designed to be screwed onto the neck of the bottle and includes a bevelled drawing-off tube intended to pierce the membrane.
