Patent number: 7392922Abstract: A fuel cell for use with a combustion tool for delivery of a predetermined amount of fuel with each stem actuation is provided and includes a housing defining an open end enclosed by a closure. A main valve stem has an outlet, disposed in operational relationship to the open end and reciprocating relative to the housing at least between a closed position wherein the stem is relatively extended, and an open position wherein the stem is relatively retracted. A fuel metering valve is located within the housing, associated with the main valve stem, including a fuel metering chamber disposed in close proximity to the closure and configured so that when the stem is in the open position, only a measured amount of fuel is dispensed through the outlet. In a preferred embodiment, the fuel cell housing includes a separate fuel container, and the fuel metering valve includes a valve body having a second end opposite the fuel metering chamber located within the container.Type: GrantFiled: April 19, 2004Date of Patent: July 1, 2008Assignee: Illinois Tool Works Inc.Inventors: Valery H.

Patent number: 6786378Abstract: An auxiliary elastomeric sealing adaptor is disclosed which effectively provides a high degree of sealing, and prevents fuel leakage, between the metering valve stem and the tool stem components 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. The sealing adaptor is mounted upon the free or distal end portion of the metering valve stem and is seated within a counterbored region of the fastener-driving tool stem.Type: GrantFiled: January 9, 2002Date of Patent: September 7, 2004Assignee: Illinois Tool Works Inc.Inventors: Mohamed K.
