본 발명의 목적은 윤활 층 없이 유리 실린더에 대하여 이용될 수 있는 피스톤-실린더 배열을 제공하는 것이다. 이 목적을 위해서, 실린더 내벽(30) 상의 피스톤의 마찰을 감소시키기 위해 피스톤-실린더 배열(4)용 유리 실린더(3)를 처리하는 방법으로서, 유리(2)의 표면 에너지가 실린더 내벽(30)에 의해 확정된 내부(31)에서 상승되고, 이로써 유리(2)의 물과의 접촉각이 낮아지는 것인 방법이 제공된다. A method of treating a glass cylinder for a piston-cylinder arrangement for reducing the friction of a piston on an inner cylinder wall of the glass cylinder includes: elevating surface energy of glass of an interior bounded by the inner cylinder wall and hence lowering a contact angle of the glass with water. The contact angle is lowered by: a gas discharge that acts on the glass at the inner cylinder wall and is generated by an electric or electromagnetic field; or the action of ozone on the glass surface. The glass with the lowered contact angle is contacted with water to form a water film on the contacted glass.
