Abstract
A plunger pressure accumulator includes a shell; and a plunger which is adapted to move relative to the shell into an interior space of the shell. The interior space is divided into at least two subspaces, a first subspace of which is suppliable with hydraulic fluid of an external system and a second subspace which is provided with a pressurized gas. Between the plunger and the shell is arranged a slide element upon which the plunger is supported to move to a distance apart from an internal surface of the first subspace and from an internal surface of the second subspace. The plunger pressure accumulator is provided with at least one regenerator which is stationary relative to the shell or the plunger.
