Abstract

"PISTãO ELìPTICO DE MOLA PNEUMáTICA". A presente invenção refere-se a um pistão de mola pneumática de compensação de carga lateral que apresenta uma seção transversal elíptica. A mola pneumática de compensação de carga lateral compreende uma luva de mola pneumática que forma uma câmara e que apresenta um lóbulo de rolamento. Uma extremidade da luva é conectada a um tampão extremo inclinado para a compensação de carga lateral. A outra extremidade da luva apresenta um lóbulo de rolamento engatado com a superfície externa elíptica do pistão. A superfície externa elíptica do pistão é disposta em um ângulo de 90<198> com relação a uma distribuição de tensão elíptica na luva, tornando assim uniforme a distribuição de tensão na porção de lóbulo de rolamento da luva, à medida que ela rola no pistão.
