High-pressure piston cylinder unit

摘要: High-pressure piston cylinder unit with a (2) and (5, 126, 136) moving within said having free end, the front surface (52) of which, arranged perpendicularly to 136), forms movable wall high-pressure chamber (3) in cylinder. Said is characterized that limiting gap between has one or several limited sections, where it more extensive widthwise order provide pressure compensation. The can be extended by decreasing diameter area means grooves inside wall.
