Abstract

ACIONADOR HIDROPNEUMáTICO REGENERATIVO A invenção refere-se a um acionador hidropneumático aplicável aos acionamentos lineares, compreendendo disposições tendo por objetivo gerar de maneira interna e regenerativa uma pressão hidráulica a partir do movimento das partes móveis. Estas disposições permitem ao mesmo tempo desacelerar o movimento regulando finamente sua velocidade quando isto é necessário para a utilização. O acionador compreende um pistão pneumático (Pp) anular provido de um tubo móvel (21) montado na parte interna do pistão, o pistão pneumático (Ep) podendo se deslocar dentro de um cilindro externo (Cy) sob efeito de um diferencial de pressão aplicado a partir do exterior por conexões pneumáticas (Xl, X2). O acionador é provido além disto de um pistão hidráulico (Eh) coaxial munido de uma haste (10) deslizante dentro de uma camisa coaxial fixa (19, 20) separando os dois pistões, estes sendo solidários entre si por uma conexão mecânica (11) entre a extremidade da haste (10) do pistão hidráulico e a extremidade do tubo móvel (21) O acionador compreende além disto comportas de comando elétrico ou pneumático, restrições ajustáveis, válvulas anti-retorno, e um reservatório de óleo (l5) mantido sob pressão por uma mola (16) ajustável por uma rosca (1). O reservatório pode ser posto em conexão por meio de comportas, restrições ajustáveis e válvulas anti-retorno, com os dois lados do pistão hidráulico.REGENERATIVE HYDROPNEUMATIC DRIVER The invention relates to a hydropneumatic actuator applicable to linear drives, comprising arrangements for the purpose of internally and regeneratively generating a hydraulic pressure from the movement of moving parts. These arrangements allow at the same time to slow down the movement by finely adjusting its speed when necessary for use. The actuator comprises an annular pneumatic piston (Pp) provided with a movable tube (21) mounted inside the piston, the pneumatic piston (Ep) being able to move within an external cylinder (Cy) under the effect of a pressure differential applied from outside by pneumatic connections (Xl, X2). The actuator is furthermore provided with a coaxial hydraulic piston (Eh) provided with a sliding rod (10) within a fixed coaxial sleeve (19, 20) separating the two pistons, which are integral with each other by a mechanical connection (11). between the piston rod end (10) and the movable tube end (21) The actuator further comprises electric or pneumatic control gates, adjustable restraints, non-return valves, and an oil reservoir (l5) held under pressure by a spring (16) adjustable by a thread (1). The reservoir can be connected through gates, adjustable restraints and non-return valves on both sides of the hydraulic piston.
