Abstract
A piston accumulator () comprises a pressure chamber () which on one side is closed by a piston () axially displaceable in a pipe () in order to change its volume depending on the axial position of the piston (). A detent mechanism is provided in order to hold back the piston () against a spring preload () in a second position differing from a first position. The piston () is formed in a multi-part fashion and comprises at least a first piston part () and a second piston part (), wherein at least one of the two piston parts () is hardened and disposed to cooperate with the detent mechanism in a catching fashion.
