Problems solved by technology

It reduces the life of the fuel tank due to product leakage not only from the internal seals in the tank, but also through the seals located in the valves
[0005] An important disadvantage of the second system, not only is there more leakage, but it is also complicated for the user
Also, attempting to fit the fuel tank with the shipping cap still in place can cause extensive damage to the tool

Embodiment Construction

[0024] see now figure 1 and 2 , it can be seen that a prior art valve 4 is secured to the fuel tank 12 in a detached position by means of a securing cap or shipping cap 6 . As known in the art, such as figure 1 As shown, in order to move from the disengaged position to the engaged position, the user must first disassemble the retaining cap 6 together with the prior art valve 4 (these two parts are now connected together by a snap fit). The user then needs to disengage the retaining cap 6 from the prior art valve 4 and then place the prior art valve 4 on the fuel tank 12 to snap it into the engaged position. The engaged position is described in the prior art valve 4 engaged with the fuel tank 12. figure 1 can be seen in .

[0025] It is also known in the prior art that the fuel tank 12 is transported by fully engaging the prior art valve 4, as figure 1 shown. Because the prior art valve 4 is fully engaged with the fuel tank 12, the prior art valve is exposed to the liquid...

Abstract

A valve configured for use with a fuel cell in both a disengaged position, in which the valve has not established fluid communication with the fuel cell, and an engaged position, in which the valve has established fluid communication with the fuel cell. The valve includes a body having a first formation for maintaining the disengaged position, and a second formation for maintaining the engaged position.

Description

technical field [0001] The present invention relates to improvements to an external metering valve for use with a fuel tank, liquefied gas tank or dispenser for dispensable fluids. Background technique [0002] As described in U.S. Patent Nos. 4,403,722, 4,483,474, 4,522,162 and 5,115,944 to Nikolich, all of which are incorporated by reference, it is known to dispense hydrocarbon fuels using a dispenser for dispensable liquids. Dispensed into a gas-powered tool, such as a gas-powered valve driver tool. Such valve actuation tools, as well as such fuel tanks, are commercially available from ITW-Paslode, a division of Illinois Tool Works, Inc., of Vernon Hills, Illinois, under the trademark IMPULSE. In particular, one suitable fuel tank is disclosed in the aforementioned Nikolich US Patent No. 5,115,944. [0003] Two systems are known for securing an external metering valve to such fuel tanks. In a first known system, the valve is fully engaged with the ...
