Abstract

"LIMITADOR POROSO PARA MANCAL DE GáS". A presente invenção refere-se a um limitador de gás particularmente útil para aplicação em um mancal de gás conforme usado, por exemplo, em uma maquinaria de ciclo "Stirling" de pistão livre. O material de tira poroso juntamente com uma chapa de encosto e um orifício (orifício de sangramento) é usado de modo a prover a restrição ao fluxo de gás para dentro de um entreferro anular entre um pistão e um cilindro.
