Abstract

''CABEçA DE CHAVE DE CATRACA''. A presente invenção refere-se geralmente a mecanismos de catraca pneumáticos e em particular a um dispositivo para auxiliar na retenção do eixo de encaixe durante a reconfiguração da catraca. De acordo com a presente invenção, pelo menos um recesso é fornecido no eixo de encaixe de uma cabeça de catraca para receber uma mola no mesmo. A extremidade da mola é cumprimida contra uma superfície interna da cabeça de catraca para reter por fricção o eixo de encaixe e a ling³eta da catraca durante o golpe de reconfiguração da forquilha de catraca.
