Abstract

"LUVA DE MOLA DE AR". A presente invenção refere-se a uma luva de mola de ar. A luva compreende um corpo de elastómero que tem duas camadas. Cada camada compreende uma corda embutida no corpo de elastómero. Cada corda está enrolada ao redor da luva em uma direção oposta da outra e cada uma tendo um ângulo de hélice. O primeiro ângulo de hélice de corda e o segundo ângulo de hélice de corda compreendem um ângulo de hélice diferencial de corda. O primeiro ou ângulo de hélice de corda interno é maior do que um segundo ou ângulo de hélice de corda externo. O ângulo de hélice diferencial de corda está na faixa de aproximadamente 0<198> a 2,5<198>.
