Embodiment Construction

[0086] Referring to the accompanying drawings (Figs. 1 to 6) by way of example only, an externally refillable metered dose valve for use with a fuel tank, aerosol canister, or dispenser for a dispensable fluid is presented, The fluid is held under pressure in the fuel tank, aerosol can, or dispenser, but can be released when the valve system is opened and exits the fluid stream, fluid spray, in a continuous stream or in intermittent sprays Wait.

[0087] In particular, the present invention relates to an externally fillable metering valve 1 for dispensing hydrocarbon fuel for automatic gas feed drive tools.

[0088]Figures 1 to 6 illustrate a possible embodiment of lifting means. A fuel tank typically includes a tank body 2, an inner fuel bag for storing gas, a gas space between the fuel bag and the inner surface of the fuel tank (the gas space is also typically filled with the same gas as the gas in the fuel bag) , to apply pressure to the gas contained in the bag), and the...

Abstract

This invention relates to a refillable external dosing valve for use with a fuel cell, aerosol can, or dispenser for a dispensable fluid. In particular, the invention relates to a refillable external dosing valve for use in dispensing a hydrocarbon fuel for a gas auto-feed drive tool. The refillable dosage valve includes an entry point and a non-return valve so that the fuel canister is able to be reloaded after the fuel bag internally of the canister has been totally deflated. The valve is adapted to engage the fuel canister in a manner allowing the valve to establish fluid communication with the fuel in the canister and to co-operate with a refilling nozzle of apparatus adapted to deliver a substance from a reservoir through the dosing valve to refill a receptacle with said substance, with which the dosing valve is used. The valve is also configured to include an internal metering feature which enables a predetermined amount of fuel to be delivered to a metering chamber within the gas auto-feed drive tool. The invention also provides a system to enable removal of residual gas within a canister to be removed when the canister is to be disposed of.

Description

technical field [0001] The present invention relates to a refillable external dosing valve adapted for use with a fuel tank, aerosol canister, or dispenser for a dispensable fluid. In particular, the present invention relates to an externally fillable metering valve for dispensing hydrocarbon fuels for automatic gas feed powered tools. [0002] The refillable dosing valve includes an entry point and a check valve so that the fuel tank can be refilled after the inner fuel bag of the fuel tank is completely deflated. The externally fillable dosing valve is also configured to include internal metering features that enable a predetermined amount of fuel to be delivered to a metering chamber within the auto-gas drive. The metering valve is adapted to engage the fuel tank in a manner that allows the metering valve to establish fluid communication with fuel within the tank. [0003] The externally fillable metering valve is also adapted to cooperate with a refill nozzle of the devi...
