Abstract

DISPOSITIVO DE INJEÇÃO E COMPONENTES DO MESMO. A presente invenção é dirigida a um dispositivo de injeção e um método de utilização do mesmo. O dispositivo de injeção inclui um conjunto de acionamento de injeção, que inclui uma câmara de pistão pneumático, uma câmara de dosagem, um pistão pneumático posicionado de forma deslizante na câmara de pistão pneumático e um pistão injetado posicionado de forma deslizante na câmara de dosagem. Em um aspecto, o conjunto de acionamento de injeção é configurado de modo que qualquer energia resultante de uma aplicação de força ao conjunto de acionamento de injeção esteja instantaneamente disponível para o início de um ciclo de injeção. Em outro aspecto, o dispositivo de injeção inclui membros resilientes respectivos separados para cada um dentre o pistão pneumático e o pistão injetado que são configurados para posicionar cada um dentre o pistão pneumático e o pistão injetado no posição de pré-injeção. Ainda em outro aspecto, o dispositivo de injeção inclui um conjunto de válvula com uma válvula que é configurada para fornecer fluido pressurizado para a câmara de pistão pneumático quando a válvula está em uma posição aberta. A taxa do movimento da válvula entre a posição fechada e a posição aberta é independente de controle por um usuário do dispositivo de injeção.
