Abstract

La présente invention a pour objet un moteur à explosion deux temps à crosse comportant un système de distribution à chemise rotative.The subject of the present invention is a motor with two-stroke buttstock explosion including a rotary liner distribution.

Il est constitué d'un moteur à explosion deux temps de type à crosse (3) comportant, d'une part, un cylindre (1) à double parois (10 11) entre lesquelles tourne un fourreau cylindrique (12) pourvus d'orifices contrôlant l'ouverture des lumières d'admission (13) et d'échappement (14) et, d'autre part, un piston auxiliaire (9) disposé dans le carter (6) de vilebrequin et destiné à comprimer les gaz frais pour assurer un bon remplissage de la chambre d'explosion en même temps qu'un balayage très efficace des gaz brûlés.It consists of a two internal combustion engine stock type time (3) comprising, on the one hand, a double-walled cylinder (1) (10 11) between which turns a cylindrical sheath (12) provided with orifices controlling the opening of the intake lights (13) and exhaust (14) and, on the other hand, an auxiliary piston (9) arranged in the crankcase (6) and intended compress fresh gases to ensure proper filling of the explosion chamber at the same time as a sweep very efficient burnt gases.

Il est destiné d'une façon générale à améliorer le rendement des moteurs à explosion à deux temps, c'est à dire dans lesquels les phases d'admission, de compression, de combustion, de détente et d'échappement s'effectuent durant un seul tour du vilebrequin, et plus particulièrement les moteurs deux temps Diesel ou à injection d'essence.

Figure 00000001
It is generally intended to improve the efficiency of two-stroke internal combustion engines, that is to say in which the intake, compression, combustion, expansion and exhaust phases take place during one single turn of the crankshaft, and more particularly two-stroke diesel or petrol injection engines.
