Abstract: Disclosed is a piston accumulator having an accumulator housing (10) and a separator piston (12), which can be moved longitudinally in the accumulator housing (10) and separates two media spaces (14, 16) from each other, which is characterized in that an end-position cushioning (28) is provided between the separator piston (12) and the accumulator housing (10), which end-position cushioning (28) has at least one gap (66, 72) that narrows as the motion of the separator piston (12) increases in the direction of its end position and in that way builds up a flow resistance, which inhibits the motion of the separator piston (12), and which is introduced as a recess (64, 78) into at least one of the adjacent end faces (30, 56) of the separator piston (12) and the accumulator housing (10).

Abstract: Degasifying apparatus is for eliminating gases, such as ambient air, from fluids, such as oil. The apparatus has at least one permeable membrane (26) that lets the gas to be eliminated from the fluid (22) penetrate through the permeable membrane and retains the liquid moiety of the fluid within the permeable membrane.
