Abstract
A piston-type accumulator includes a separating piston (24) axially displaced inside an accumulator housing (10) and separating two spaces from one another inside the accumulator housing (10), particularly a gas side (22) from a liquid side (20) of the accumulator. Due to the fact that the separating piston (24) is predominantly or completely made of a plastic material, it can be provided with a very light weight reducing the overall installation weight of the piston-type accumulator.
