Abstract
A piston-type accumulator includes a separating piston () axially displaced inside an accumulator housing () and separating two spaces from one another inside the accumulator housing (), particularly a gas side () from a liquid side () of the accumulator. Due to the fact that the separating piston () 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.
