Abstract
a presente invenção refere-se a um dispositivo que compreende duas juntas (7, 8) conduzindo uma haste de pistão (5), as ditas juntas sendo localizadas em um lado de um pistão (4), enquanto que uma junta interna (7) divide a câmara dentro do cilindro fechado (1), em uma câmara de trabalho (10) limitada axialmente por uma superfície interna de um fundo (2), e em uma câmara de lubrificação (9) limitada axialmente pela superfície interna da junta externa (8). a câmara de trabalho (10) tem uma zona de fluxo (11) moldada como o cilindro (1) com seu diâmetro interno aumentado, colocado adjacente à junta interna (7), como também a zona de compressão (12), enquanto que o diâmetro interno do cilindro (1) é deslizadamente ajustado com o diâmetro externo do pistão (4).
