Title (EN) POPPET VALVE AND METHOD OF ITS MANUFACTURE
(FR) SOUPAPE À CLAPET ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) The present invention relates to a method for manufacturing a poppet valve or mushroom valve, comprising: providing a mixture of metal powder and a binder, filling and pressing said mixture in a mold, to obtain a green product, removing the binder from said green product, and thermally sintering said green product to a poppet valve blank, by hot isostatic pressing, and also to a poppet valve manufactured with said method.
(FR) La présente invention concerne un procédé de fabrication d'une soupape à clapet ou soupape champignon, consistant à : fournir un mélange de poudre métallique et d'un liant, remplir et comprimer ledit mélange dans un moule, pour obtenir un produit vert, retirer le liant dudit produit vert, et fritter thermiquement ledit produit vert jusqu'à obtenir une ébauche de soupape à clapet, par compression isostatique à chaud, et également une soupape à clapet fabriquée par ledit procédé.
