Title
(EN) FREE-PISTON LINEAR APPARATUS
(FR) APPAREIL LINÉAIRE À PISTONS LIBRES
Abstract
(EN)
The present invention relates to a free-piston linear apparatus, comprising a piston arranged within a cylinder, said piston being configured for linear displacement within the cylinder; a combustion chamber arranged on one side of said piston and a gas expansion chamber arranged on an opposite side of said piston, wherein said piston is drivable under the action of a fuel medium expanding in the combustion chamber; an exhaust vent arranged to release exhaust gas from the combustion chamber to an exhaust system, wherein said exhaust system comprises a heat exchanger configured to transfer residual heat from said exhaust gas to said gas expansion chamber in order to heat the gas expansion chamber; and wherein said gas expansion chamber comprises at least one gas port for injecting and/or releasing gas into/from the gas expansion chamber.
(FR)
La présente invention concerne un appareil linéaire à piston libre, comprenant un piston agencé à l'intérieur d'un cylindre, ledit piston étant conçu pour un déplacement linéaire à l'intérieur du cylindre; une chambre de combustion disposée sur un côté dudit piston et une chambre d'expansion de gaz disposée sur un côté opposé dudit piston, ledit piston pouvant être entraîné sous l'action d'un milieu combustible s'étendant dans la chambre de combustion; un évent d'échappement conçu pour libérer le gaz d'échappement de la chambre de combustion vers un système d'échappement, ledit système d'échappement comprenant un échangeur de chaleur conçu pour transférer de la chaleur résiduelle dudit gaz d'échappement vers ladite chambre d'expansion de gaz afin de chauffer la chambre d'expansion de gaz; et ladite chambre d'expansion de gaz comprenant au moins un orifice de gaz destiné à injecter et/ou libérer du gaz dans/à partir de la chambre d'expansion de gaz.
