A hand-held power tool is provided, the operational power of which is provided by a gas combustion mechanism. The gas combustion mechanism comprises a first priming cylinder (2) having a first piston (4) and an air intake valve (6). The priming cylinder (2) is fluidally connected via a transfer valve (8) to a combustion chamber (10) connected to a second delivery cylinder (12) having a second piston (14). In use, said first piston (4) is arranged to compress air and transfer compressed air to said combustion chamber (10) via said transfer valve (8). The combustion chamber (10) is arranged to receive said compressed air from the priming cylinder (2) and fuel gas from said fuel supply port (16). The air and fuel gas are mixed to form an air/fuel gas mixture therein. The combustion chamber (10) is also arranged so that said air/fuel mixture is ignited therein to impart motion onto said second piston (14) and to facilitate the operation of the tool.
Outil mécanique portatif alimenté par un système de combustion de gaz, lequel comprend un premier cylindre d'amorçage (2) à premier piston (4) et une vanne d'admission d'air (6). Ce cylindre (2) est relié fluidique via une vanne de transfert (8) à une chambre de combustion (10) reliée à un second cylindre de distribution (12) doté d'un second piston (14). Le premier piston (4) comprime l'air et transfère l'air comprimé à la chambre (10) via une vanne de transfert (8). La chambre (10) reçoit l'air depuis le premier cylindre (2) et un gaz combustible depuis un orifice d'alimentation en gaz (16). Le mélange air/gaz est établi dans ladite chambre (10), laquelle assure l'allumage du mélange pour transmettre un mouvement au second piston (14) et faciliter le fonctionnement de l'outil..
