Abstract

Boisseau en deux parties coaxiales, et moteur à source chaude externe comprenant celui-ci La présente invention concerne un boisseau (10) pour moteur à source chaude externe (1) du type comprenant : un cylindre (2), un piston (3), une culasse (4), une chambre de travail (5) pour un gaz de travail, une distribution comprenant ledit boisseau faisant sélectivement communiquer la chambre de travail avec différentes ressources. Le boisseau (10) comprend deux parties coaxiales : une partie de guidage (11) du gaz de travail, comprenant des passages internes débouchant radialement par au moins une embouchure qui communique sélectivement avec la chambre de travail (5) par au moins une lumière (41) pratiquée dans la culasse (4), et une partie de distribution (16) du gaz de travail, mobile et disposée en périphérie de la partie de guidage (11), comprenant au moins une fenêtre (17) qui fait sélectivement communiquer la chambre de travail (5) avec au moins un desdits passages internes de façon que le gaz de travail s’écoule sélectivement entre la chambre de travail (5) et les différentes ressources. La présente invention concerne également un moteur à source chaude externe comprenant ledit boisseau. Figure pour l’abrégé : Fig. 3Valve in two coaxial parts, and external hot source engine comprising the same The present invention relates to a valve (10) for an external hot source engine (1) of the type comprising: a cylinder (2), a piston (3), a cylinder head (4), a working chamber (5) for a working gas, a distribution comprising said valve selectively making the working chamber communicate with different resources. The valve (10) comprises two coaxial parts: a guide part (11) of the working gas, comprising internal passages emerging radially through at least one mouth which communicates selectively with the working chamber (5) through at least one port ( 41) made in the cylinder head (4), and a distribution part (16) of the working gas, movable and arranged on the periphery of the guide part (11), comprising at least one window (17) which selectively communicates the working chamber (5) with at least one of said internal passages so that the working gas flows selectively between the working chamber (5) and the different resources. The present invention also relates to an external hot source engine comprising said valve. Figure for the abstract: Fig. 3
