Title (EN) IMPROVED MULTIPLE STAGE REED VALVES FOR USE IN INTERNAL COMBUSTION ENGINES
(FR) SOUPAPES FLEXIBLES MULTI-ETAGEES AMELIOREES, DESTINEES AUX MOTEURS A COMBUSTION INTERNE
Abstract: front page image
(EN)The present invention provides improved multiple stage reed valve construction for internal combustion engines. The reed valves (10) comprise first stage reed valves (12) with multiple ports (16) in the first stage reed valve (12). Beams (18) have a smoothly shaped curve from the base (20) of the first stage reed valve (12) to the apex (22) thereof and narrowing toward the apex separate adjacent ports (16). The reed valves of the present invention provide significant improvements in engine operation.
(FR)La présente invention se rapporte à une structure de soupape flexible multi-étagée pour des moteurs à combustion interne. Ces soupapes (10) comprennent une soupape flexible (12) de premier étage, présentant des orifices multiples (16). Des tiges (18) présentent une courbe régulière partant de la base (20) de la soupape flexible (12) du premier étage et se dirigeant vers le sommet de cette dernière, en se rétrécissant vers le sommet, ces tiges séparant des orifices adjacents (16). Les soupapes flexibles de la présente invention améliorent de manière notable le fonctionnement du moteur.
