Title (EN) EXTERNAL HEAT SOURCE ENGINE WITH SLIDE VALVES
(FR) MOTEUR A SOURCE CHAUDE EXTERNE A BOISSEAUX
Abstract:
(EN) The present invention concerns an external heat source engine comprising: - at least one cylinder (2), - a piston (3) that is movable back and forth in the cylinder, - a cylinder head (4) defining a working chamber (5) with the piston and the cylinder, - a heat exchanger (6) for exchanging heat between a working gas and a heat-transfer fluid, - a distribution comprising two rotary slide valves (20, 30) mounted so as to be able to rotate in the cylinder head and bringing the working chamber selectively into communication with the following resources: o a working gas inlet (A), o a cold end (B) of the exchanger, o a hot end (C) of the exchanger, o an exhaust (D). The slide valves (20, 30) comprise internal passages that open through the side wall of same through at least one opening that communicates selectively with the working chamber (5) via at least one opening formed in the cylinder head (4).
(FR) La présente invention concerne un moteur à source chaude externe comprenant : - au moins un cylindre (2), - un piston mobile (3) en va et vient dans le cylindre, - une culasse (4) définissant une chambre de travail (5) avec le piston et le cylindre, - un échangeur de chaleur (6) entre un gaz de travail et un fluide caloporteur, - une distribution comprenant deux boisseaux rotatifs (20, 30) montés en rotation dans la culasse et faisant sélectivement communiquer la chambre de travail avec les ressources suivantes : o une admission (A) de gaz de travail, o une extrémité froide (B) de l'échangeur, o une extrémité chaude (C) de l'échangeur, o un échappement (D). Les boisseaux (20, 30) comprennent des passages internes débouchant à travers leur paroi latérale par au moins une embouchure qui communique sélectivement avec la chambre de travail (5) par au moins une lumière pratiquée dans la culasse (4).
