The invention relates to a valve spring plate (10) for supporting the spring resistance of locking springs acting upon gas exchange valves in valve regulation of internal combustion engines. Said valve spring plate comprises a reinforcement part (12) which is made of a less solid material and an annular- shaped support part (14) which is made of more solid material and which is arranged between the reinforced part and locking spring in such a manner that the support part is maintained in a friction fit on the reinforcement part in order to simplify production and pre-assembly.

La présente invention concerne une cuvette de ressort de soupape (10) qui sert d'appui vis-à-vis des forces de rappel de ressorts de fermeture qui agissent sur des soupapes d'échange gazeux, dans le cadre de l'actionnement des soupapes de moteurs à combustion interne. Ladite cuvette de ressort de soupape comprend une partie de renfort (12) faite d'un matériau de dureté inférieure et une partie d'appui (14) annulaire disposée entre la partie de renfort et le ressort de fermeture et faite d'un matériau de dureté supérieure. Selon l'invention, afin de simplifier la réalisation et le pré-montage, la partie d'appui est maintenue uniquement par liaison de frottements contre la partie de renfort.
