Abstract

Patente de Invenção: <B>''MOLA DE GáS COM COMPENSAçãO DE TEMPERATURA''<D>. Uma mola de gás tem um único bypass através de êmbolo que é controlado por um membro de válvula de material elastomérico, que limita o fluxo através de bypass quando a mola de gás é comprimida (a haste de êmbolo deslocando-se para o interior do cilindro) e produz um diferencial de pressão através do êmbolo que varia inversamente com a temperatura. A força crescente opondo-se à compressão da mola de gás devido a um diferencial de pressão através de bypass quando a temperatura da mola de gás, e assim a força de saída decresce mantendo a carga de manuseio mais uniforme através de uma gama de temperatura. O membro de válvula elastomérico tem reduzido efeito sobre o funcionamento normal da mola de gás no modo de extensão (a haste deslocando-se para fora).
