Abstract

<B>MOLA A GáS DE BAIXO IMPACTO<D> Uma mola a gás tendo uma câmara de gás principal, uma câmara de gás secundária e superfícies de vedação as quais, durante uma parte do curso da haste de pistão, definem uma vedação hermética a gás entre as mesmas para proporcionar duas câmaras de gás separadas cada uma proporcionando uma força atuando sobre as haste de pistão em direções opostas uma à outra para reduzir a força líquida sobre a haste de pistão. Quando a haste de pistão está próxima de sua posição totalmente estendida as superfícies de vedação proporcionam a vedação hermética a gás e a força líquida sobre a haste de pistão é mínima e na direção para deslocar a haste de pistão para sua posição totalmente estendida. Dessa forma, até que as superfícies cooperantes sejam deslocadas para terminar a vedação hermética a gás, apenas uma ligeira força é exigida para deslocar inicialmente a haste de pistão a partir de sua posição totalmente estendida. Isso reduz bastante a força de impacto ou impulso transmitida a um êmbolo percussor de prensa mediante acionamento inicial da haste de pistão totalmente estendida. Um segundo conjunto de vedação também pode ser provido o qual controla a taxa na qual o conjunto de haste de pistão retorna para sua posição totalmente estendida. Após a vedação hermética a gás ser concluída, a mola a gás funciona geralmente como uma mola a gás convencional com uma única pressão de gás atuando sobre a haste de pistão e empurrando a haste de pistão em direção à sua posição estendida contra a força do êmbolo percussor deslocando a mesma.
