Problems solved by technology

In addition, the intermeshing of the valve stem 26 and tool valve stem 28 also limits the necessary movement of the fuel tank 20 and gauge valve 24 in the tool 10.
Finally, the activation of each continuous firing duty cycle of the fastener causes continuous or repeated pivotal movement of the valve stem 26 relative to the tool stem 28 while maintaining the aforementioned fluid interface between the two elements, which will As a result, both the valve stem 26 and the tool valve stem 28 will be subjected to bending stresses or strains, which can lead to structural fatigue, cracking, damage, failure and additional fuel leakage within the tool 10

Embodiment Construction

[0022] See now the attached drawings, especially the Figure 4 , disclosed is a fuel tank powered fastener driving tool in which a new and improved auxiliary fuel tank gauge valve stem seal adapter constructed in accordance with the principles and teachings of the present invention may be utilized, which The tool is indicated generally at 110 . Figure 4 shown in Tool 110 with figure 1 The tool 10 shown in is similar, therefore, the tool 110 and the corresponding components in the tool 10 will be indicated by corresponding reference numerals, except that the labeling of each component in the tool 110 is within the range of 100 series.

[0023]Correspondingly, briefly, since such fastener driving tools are well known in the art industry, the fastener driving tool 110 seen in the figures includes a trunk portion 101 defining a burner The combustion chamber 112 and the air-fuel mixture distribution fan 114 are arranged in the combustion chamber 112 . The piston 102 is vertical...

Abstract

An auxiliary elastomeric sealing adaptor (164) is disclosed which effectively provides a high degree of sealing, and prevents fuel leakage, between the metering valve stem (126) and the tool stem components (128) of a fuel-cell powered fastener-driving tool despite bending, tilting, or pivotal movements of the metering valve stem attendant a fastener-firing operation. In addition, the incorporation of the elastomeric adaptor between the stem components reduces the need for high tolerance manufacturing techniques and also enhances the service lives of the stem components (128). The sealing adaptor is mounted upon the free or distal end portion of the metering valve stem (126) and is seated within a counterbored region (134) of the fastener-driving tool stem (128).

Description

technical field [0001] This invention relates generally to fastener driving tools and, more particularly, to a new and improved seal adapter configured to be operatively connected to a fuel tank power source operable with a fastener driving tool Between the outwardly projecting valve stem of the (operatively) connected measuring valve and the tool valve stem of the fastener driving tool such that, during periodic firing of the normal operation of the fastener driving tool, the fuel tank relative to the tool Regardless of position or orientation, a reliable seal between the measuring stem and tool stem is always maintained. Background technique [0002] Fuel tanks are commonly used as a power supply or power source for fastener driving tools. Examples of fuel tanks and fastener driving tools employing fuel tanks are described in US Patent 5,115,944 issued May 26, 1992 to Nikolich, US Patent 4,522,162 issued June 11, 1985 to Nikolich, and issued November 20, 1984 to Nikolich ...
