Title (EN) ROTARY ENGINE VALVE
(FR) SOUPAPE ROTATIVE POUR MOTEUR
Abstract: front page image
(EN)A shaft-type valve means for an internal combustion engine (12) of the type having a block (14) in which there is a cylinder (20) and a piston (22) reciprocal in the cylinder (20) wherein the chamber (103) is covered by a head (41) and an improved valve is in the form of a shaft (36) journaled in the head (41) with a portion of the shaft (36) spanning a portion of the cylinder (20) above the piston (22) and the shaft (36) has a diametrical (90, 92) passageway of a cross sectional area which, in the direction of the centerline of the shaft (36), is at least as great as the radius of the cylinder (20) and circumferentially is a distance substantially equal to one-sixteenth of the circumference of the shaft (36) and wherein seal means (501, 601) are provided between the shaft (36) and the engine and a crank shaft (28) connected to the piston (22) is connected to the shaft (36) to rotate it simultaneously with the crank shaft (28) by a force transmission means such as a belt or the like.
(FR)Soupape du type a arbre pour moteur a combustion (12) ayant un bloc (14) contenant un cylindre (20) et un piston (2) anime d"un mouvement de va et vient dans ce cylindre (20), dans lequel la chambre (103) est recouverte par une tete (41), et une soupape amelioree a la forme d"un arbre (36) ajuste dans la tete (41), une partie de cet arbre environnant une partie du cylindre (20) au dessus du piston (22) et l"arbre (36) possede un orifice de passage, place diametralement (90, 92) d"une surface de coupe transversale qui, dans la direction de la ligne de centre de l"arbre (36) est au moins aussi grande que le rayon du cylindre (20) et dont la circonference est sensiblement egale a un seizieme de la circonference de l"arbre (36), et dans lequel des moyens de scellement (501, 601) sont fournis entre l"arbre (36) et le moteur et un vilebrequin (28) relie au piston (22) est relie a l"arbre (36) de maniere a le faire tourner simultanement avec le vilebrequin (28) par un moyen de transmission de force telle qu"une courroie ou analogue.
