Patent number: 11738433Abstract: A fastener driving tool for fixation of parts by way of nails or staple propelled by a driving piston under the effect of the combustion of one or more fluids. More specifically, a device of controlling the relative proportions of the fluids used for combustion including a combustion chamber having a first inlet port for inputting a first fluid having at least one variable fluid characteristic, and a second inlet port for inputting a second fluid. A first actuator is operably coupled to said first inlet port, adapted to switch between a first open state, allowing said first fluid to move into said combustion chamber at a first mass flow rate that is dependent on said at least one variable fluid characteristic, and a first closed state, preventing or at least limiting said first fluid from moving into said combustion chamber.Type: GrantFiled: August 3, 2021Date of Patent: August 29, 2023Assignee: Illinois Tool Works Inc.Inventors: Pascale Grandjean, Médéric Cartier, Romain Nony

Patent number: 10456897Abstract: The present disclosure concerns a method and an electronic ignition control device of a combustion chamber of a gas-powered fixing tool designed to optimize the quality of the shooting of fixation elements by the tool. According to the principle of the present disclosure, the triggering of the ignition of the chamber to produce the shot is commanded on the condition that the time between the moment when the user places the tool against a work surface and the moment when he pulls on an actuation trigger of the tool is greater than a predefined delay time, to ensure an optimal filling of the combustion chamber with the combustible gas. According to one embodiment of the present disclosure, the triggering of the ignition is enabled on the supplemental condition that a signal of medium ignition voltage is greater than a trigger threshold voltage.Type: GrantFiled: December 14, 2016Date of Patent: October 29, 2019Assignee: Illinois Tool Works Inc.Inventors: Pascale Grandjean, Pierre Cordeiro, Patrick Herelier, Frederic Nayrac, Alain Vettoretti

Patent number: 8701957Abstract: This invention relates to controlling a tool for driving fastening elements through firing a fuel. A valve, upon each shot, opens via a current (IA) in a component created by a voltage injection control (Uv). Upon the first one of a series of shots and after the control, the time to is detected of a drop of current in a measuring member upon the transient rise of current and, the opening period To of the valve being predetermined, the end of the injection control is triggered at the time td, after a period To, following the time to, reduced with a period To, of a first rise of the voltage injection control following the beginning of the drop of current or a rise, following the beginning of its drop, of the current.Type: GrantFiled: January 19, 2011Date of Patent: April 22, 2014Assignee: Societe de Prospection et d'Inventions Techniques SPITInventors: Pascale Grandjean, Pierre Cordeiro, Jean-Michel Dreveton

Publication number: 20140069981Abstract: A gas setting tool, wasting a limited amount of fuel. The tool comprises i) an internal combustion engine, with a device for injecting fuel in the chamber of the engine, comprising a check valve and an injection piston, the injection piston extending beyond the check valve, and iii) a sealing joint mounted on the injection piston of the check valve. The injection piston comprises an internal bore opened on the exterior and the check valve and its injection piston are arranged so that, in an opening position, the fuel in a container is able, outside the check valve, to only flow through the internal bore of the injection piston. Thanks to this invention, fuel waste is reduced to the best.Type: ApplicationFiled: September 22, 2011Publication date: March 13, 2014Applicant: SOCIETE DE PROSPECTION ET D'INVENTIONS TECHNIQUES SPITInventors: Christian Ricordi, Alain Vettoretti, Frederic Nayrac, Patrick Herelier, Pascale Grandjean, Pierre Cordeiro, Jean-Michel Dreveton

Patent number: 7766205Abstract: The tool includes a cylinder inside of which is slidably mounted a piston for driving a fastening element, as a result of the explosion inside of a combustion chamber of a mixture of gas and air that has been injected therein from a gas cartridge, after which the tool has come to bear weight against a support, the head switch has retracted and the combustion chamber has closed, followed by actuation of the trigger switch for controlling the spark plug. The tool also includes an element for determining the rate of fire which includes a real-time clock designed to cooperate with a microcontroller of an operating and control module. The arrangement applies well to fastening tools.Type: GrantFiled: October 12, 2006Date of Patent: August 3, 2010Assignee: Societe de Prospection et d'Inventions Techniques SpitInventors: Pierrick Calvet, Florent La Bella, Pascale Grandjean, Nicolas Guihard
