Metering valve for dispensing a fluid product, having a valve body containing a metering chamber defined by a chamber insert and two annular seals, a valve seal and a chamber seal. The chamber insert has a cylindrical wall, an upper edge cooperating with the valve seal and a lower edge that cooperates with the chamber seal. A valve slides axially in the valve body between a rest position and a dispensing position, so as to selectively dispense the contents of the metering chamber, the valve being urged towards its rest position by a spring that cooperates with the valve body and with the valve. The upper edge of the chamber insert has an annular cutout formed on the radially inner side of the upper edge, so that the width of the upper edge in contact with the valve seal is always the same, whatever the width of the cylindrical wall.

Various embodiments of the present disclosure provide a combustion-powered fastener driving tool fuel cell assembly including a fuel cell, fuel cell adapter, and fuel cell adapter cap for a combustion-powered fastener driving tool. The fuel cell, the fuel cell adapter, and the fuel cell adapter cap enable both the fuel cell adapter and the fuel cell adapter cap to be attached to a fuel cell and particularly a sealing member of the fuel cell in one efficient step. This single step process can be done manually or automatically, and is substantially more efficient and less time-consuming than the known fuel cell assemblies.

A method of detecting the presence of a product sprayed onto an application surface, in which the product to be applied to the application surface is sprayed onto a target zone of the application surface in pulses. Before spraying the product it is heated to a temperature higher than a predetermined temperature value. After spraying the product, a value of a parameter representing the temperature of the target zone is measured remotely, and the value of that parameter is compared to a reference value of that parameter. A detection installation including pulsed spraying by way of forming part of a device shared with the heating element.

A non-electrically powered automatic dosing and spraying valve assembly for a container of pressurized fluid with an outlet valve is described, wherein the valve assembly comprises a housing containing at least two chambers wherein one of those chambers is a main chamber open at one end to the contents of the container and closed at one end by a movable plunger, and another of those chambers is a dose chamber closed at one end by the movable plunger and closed at the other end by a prodder seal formed between a movable prodder and a fluid outlet opening; wherein the movable plunger is biased against movement toward the dose chamber by a main spring means and a prodder spring means, the main spring means being mounted in or adjacent to the dose chamber and the prodder spring means being connected to both the movable plunger and movable prodder, the assembly further comprises a fluid leak path between the main chamber and the dose chamber; and wherein the assembly is arranged such that, in use, one movable component of the assembly is configured to move relative to another component of the assembly to temporarily expose the dose chamber to the full fluid pressure of the main chamber.
