Patent DE-2756965-A1 (DE)
Title: Dissolved gases release system - with double acting piston in cylinder producing negative pressure
Inventor: HEDERMANN DIETER DIPL ING
IPC: B01D19/00
Filed: 1977-12-21
Abstract: Gases which are dissolved in liqs. e.g. the hydraulic systems of aircraft, are sepd. in a liq.-filled cylinder with a double-acting piston. When the volume of a cylinder side becomes grater than the volume occupied by the incoming liq., the inside pressure is reduced and dissolved gases are released for collection at a certain point. This removes dissolved gases continuously without requiring extraneous electric power. The satn. pressure lies below the lowest pressure during operation and standstill of the hydraulic system. It can be operated in a bypass to avoid interference with the continuous fluid flow.
