Abstract

UM DISPOSITIVO DE INJEÇÃO- A presente invenção se refere a um dispositivo de injeção para o envio de uma composição líquida, que compreende um alojamento em geral alongado, arranjado para reter um cartucho intercambiável contendo a composição líquida. O alojamento compreende um dispositivo de acionamento, e a haste de êmbolo de mergulho conectada com o dispositivo de acionamento e conectada a um êmbolo de mergulho dentro do cartucho, quando o cartucho é mantido no alojamento, para acionar o êmbolo de mergulho dentro do cartucho. O êmbolo de mergulho compreende um elemento de conexão de haste conectado com a porção de extremidade dianteira da haste de êmbolo de mergulho. O elemento de conexão de haste tem uma porção de abertura de entrada definida por seções de parede do elemento de conexão de haste, a largura da porção de abertura de entrada sendo menor do que a largura da porção de extremidade dianteira. A largura da porção de haste adjacente a e atrás da porção de extremidade dianteira no máximo corresponde a uma largura da porção de abertura de entrada. As seções de parede são flexíveis para permitir que a porção de extremidade dianteira passe da porção de abertura de entrada ao se exercer uma força de abertura nas seções de parede. O elemento de conexão de haste compreendendo uma porção de parada de haste, em que há um jogo longitudinal entre a haste de êmbolo de mergulho por um lado e a porção de abertura de entrada e a porção de parada de haste por outro lado, desse modo permitindo que a porção de extremidade dianteira se mova para frente e para trás entre a porção de abertura de entrada e a porção de parada de haste sem mover o êmbolo de mergulho.
