Abstract

o dispositivo de injeção automática compreende uma mola de injeção (24), deformável entre um estado comprimido antes da utilização do dispositivo de injeção automática e um estado distendido depois da injeção. ele compreende um órgão de comando de pistão (22), configurado para aplicar uma força sobre um pistão (40) sob a ação da mola de injeção (24) para permitir o deslocamento do pistão (40) na direção distal do dispositivo de injeção automática. o órgão de comando de pistão (22) leva um batente (118) escamoteável entre uma configuração ativa de retenção da mola de injeção (24) no estado comprimido e uma configuração escamoteada de liberação da mola de injeção (24). o dispositivo de injeção automática compreende igualmente um órgão de travamento (122) do batente escamoteável (118) em sua configuração ativa, este órgão de travamento (122) podendo tomar uma posição de travamento, na qual ele exerce uma pressão sobre o batente escamoteável (118) para impedi-lo de tomar sua configuração escamoteada, e uma posição de destravamento na qual o batente escamoteável (118) é liberado.
