Abstract

A gas piston accumulator with a piston-cylinder unit, the hydraulic space of which can be connected to a hydraulic line. A pressure piston biased with a biasing force acts on the hydraulic space in order to pressurize the hydraulic fluid in the hydraulic line with an accumulator pressure. The biasing force is achieved by a gas pressure in a gas space which is separated from the hydraulic space via the pressure piston, at least one cylinder base of the gas piston accumulator being assigned to the pressure piston as a mechanical stop, and the pressure piston having an axially set back piston main body, on the gas side of which and/or on the hydraulic side of which there protrudes a stop structure which is of reduced area compared to the respective pressure piston side and which can be brought into pressure contact with the cylinder base.
