Abstract

A piston accumulator has a dividing piston (22) inside an accumulator housing (2) that separates a chamber (28) containing a working gas, such as nitrogen, from a chamber (26) containing a working fluid, such as hydraulic oil. The dividing piston (22) is longitudinally movably guided in a guide tube (24). The guide tube (24) is arranged inside the accumulator housing (2) and extends at least partially along the housing longitudinal axis (10).
