Abstract: A dispensing device is disclosed for a fluid product, activated by inhaling, which includes a product reservoir (20), a pump or dosing valve (30), and an activating device controlled by inhaling. The activating device includes a control element (3) and an actuating member (7). The actuating member (7) is urged towards its actuating position when the control element (3) is in its control position. A retaining element (8) is provided, which is mobile between a retaining position and a releasing position. Further provided is a cam element (2), which is urged towards its storing position and is moved into its inhaling position when the user of the device inhales. The retaining element (8) is elastically deformable between its retaining position and its releasing position. The retaining element (8) is urged towards its releasing position by the actuating member (7) when the control element (3) is in its control position.

Abstract: A dispenser device which has a pumping device, an ejection nozzle incorporating a dispensing orifice, an actuator for activating the dispenser such as a pusher, and a closure system which enables the dispenser device to be closed, thereby avoiding problems such as contamination or drying out of the dispensing substance. The closure system contains a closure element that is resiliently deformable to go between a closed position in which it hermetically closes the dispensing orifice, and an open position in which it opens the dispensing orifice. When the dispensing device is actuated, the closure element is deformed into its open position by a member solid with the ejection nozzle or the ejection nozzle, and the closure element returns resiliently into its closed position after the dispensing device has been actuated.

Abstract: A device for dispensing a fluid substance contained in a container (1) provided with an opening has an element (2) that is movable between a rest position in which it closes the opening of the container (1) and an actuated position, a connection between the inside of the container and an expulsion channel (10) for expelling the substance, and an actuator member (6) for moving the element towards its actuated position. The element slides in a sealed manner inside the container so that the substance is expelled via the expulsion channel. The element includes a sealing ball (5) which, in the rest position of the element, cooperates with the element to increase interference between the element and the container, thereby guaranteeing total hermetic closure of the container.

Abstract: A device is provided for emptying a metering chamber of a powder dispenser. The dispenser includes an expulsion channel passing through the metering chamber and a device for delivering an air flow which is intended to pass along the expulsion channel to empty the metering chamber when the dispenser is actuated. A flow device is adapted to configure the air flow in such a manner that it empties the metering chamber completely. The flow device is disposed in the expulsion channel upstream from the metering chamber in the flow direction of the air flow.

Abstract: A reloadable auto-injector including a housing portion (1, 101) designed to receive a syringe (3), and a cover portion (2, 102), the auto-injector incorporating an injection device for automatically injecting the substance contained in the syringe, the injection device comprising: a piston (21) comprising a high portion (21b) and a low portion (21c), the low portion (21c) co-operating with the plunger of the syringe, the piston (21) being mounted to move, under the effect of an actuating spring (22) between a cocked position and an end-of-stroke position, the spring (22) being compressed in the cocked position; and trigger means (19) mounted to move between a blocking position in which they hold the piston (21) in its cocked position, and a releasing position in which they release the piston (21), the trigger means (19) being released from their blocking position by an actuating member; the auto-injector being characterized in that it further includes recocking means for recocking the automatic injection devi

Abstract: A device (2) for pre-dosing a powder for a dispenser that includes an expulsion channel (12), the device being characterized in that it comprises at least one hermetically closed reservoir (4) each containing a dose of powder that is to be expelled on each actuation of the dispenser, said dispenser including a transfer device (16, 17) designed to transfer an entire dose of powder from one of said at least one reservoir (4) towards said expulsion channel (12) on each actuation of the dispenser, said transfer device (16, 17), when actuated, exerting pressure on a portion of a reservoir (4), each reservoir (4) including a closure wall (6) adapted to open totally and in predetermined manner towards the outside of the reservoir under the effect of the pressure created by actuating said transfer device (16, 17). A transfer element such as an insert (1) may optionally be placed in each reservoir (4).

Abstract: Dispensing device for underwater respiration apparatus having a plurality of floating valves operating according to an improved system with pivots free from mechanical connections, said device being constructed in a single piece and comprising a central three-way distributor leading the compressed air or gas towards the center of the undersurface of a diaphragm of the floating valve, said diaphragm being located in a chamber containing a spacer member and, above the center, in a suitable central seat and loaded by a very weak spring, a service small valve with upright stem having fixedly mounted thereon an arm that operates in an upper chamber and is directly acted upon by the main control diaphragm, wherein the latter chamber communicates, through a suitable passage, both with the inspiration opening and with the expiration opening the latter containing a non-return valve, and also with the space below the undersurface of the diaphragm of said floating valve.

Abstract: High-pressure valve provided with internal opening and closing members which are indirectly actuated by a handwheel and a servo-control system based on the balancing effect generated by the same pressure of compressed air or gas or the like to be dispensed so as to obtain a very sensitive operation, the assembly being particularly suitable for compressed air or gas bottles or the like.

Abstract: A drive mechanism for pressure-gages in general, comprising a main body which can support all the members, and which is made by molding a plastic material with simultaneous embedding therein of an end of a Bourdon tubular spring, said end having fixedly inserted therein a small tube, which is also embedded in the plastics body in the same molding operation and which ensures the communication with the pressure source. The movable end of said Bourdon tube has integrally-formed thereon an eye member for connection with an S-shaped link which can actuate the indicating means of the pressure-gauge.
