Abstract

uma mola a gás com um invólucro com uma parede lateral que se prolonga axialmente, uma extremidade aberta e uma parede de extremidade fechada afastada da extremidade aberta e uma câmara de pressão fornecida em parte pelas paredes para receber gás sob pressão e uma haste de pistão recebida de forma deslizante em um alojamento recebido no invólucro e móvel entre posições estendidas e retraídas. um anel de alívio de pressão suportado de forma deslizante ao redor da haste de pistão e normalmente projetando-se axialmente para fora do alojamento pode ser deslocado axialmente para dentro durante uma condição de sobrecurso da haste de pistão para deslocar uma parte da vedação da haste de pistão para abrir um trajeto de alívio de sobrepressão para permitir que gás pressurizado na câmara de pressão escape para o exterior da mola a gás.
