Hydropneumatic pressure store - has membrane dividing housing and gas chamber filled with incompressible filler

摘要

Hydro-pneumatic pressure store with a two-part housing and a compressible membrane which divides the inside of the housing into a gas chamber and a fluid chamber of variable size where, at its edge region, the membrane is so pressed against the inner wall of one of the housing halves by means of a holding component. The inner face of the housing, extending from the middle zone, corresponds to the shape of the undeflected membrane. The inner face of the pressure store on the other side of the middle zone is greater than the face of the undeflected membrane. The gas chamber (10) of the space between the inner face (18) of the housing (2,3) and the inverted undeflected membrane (9) is filled with an incompressible, gas-impermeable fillter (19).
