Abstract
INJETOR DESCARTÁVEL COM ALTA SEGURANÇA DE INJEÇÃO. A presente invenção refere-se a um injetor descartável sem agulha com uma carcaça (10), que compreende, pelo menos, uma barra de pressão, com uma unidade de cilindro e êmbolo (100), com um punção de acionamento do êmbolo (60), com uma unidade de liberação (80), e com um acumulador de energia de mola (50), sendo que, a unidade de liberação (80) bloqueia o acumulador de energia de mola (50) pré-tensionado, primeiramente por meio da barra de pressão, sendo que, durante a liberação da barra de pressão a unidade de liberação (80) desliza ao longo de, pelo menos, um elemento de liberação (82), e sendo que, após a liberação da unidade de liberação, por meio do punção de acionamento do êmbolo o acumulador de energia de mola desloca a barra de pressão e aciona a unidade de êmbolo e cilindro. Para isso, durante o carregamento pelo acumulador de energia de mola, o acoplamento entre a parede interna do elemento de liberação e a superfície de contato da barra de pressão, voltada uma para a outra, pelo menos, parcialmente apresenta um coeficiente de fricção cinética mais alto que o acoplamento entre a superfície do colar do punção de acionamento do êmbolo e a superfície de apoio da barra de pressão voltada uma para a outra. Com a invenção em questão é desenvolvido um injetor descartável, em cujo emprego é assegurado a força mínima necessária de pressão por contato.
