Abstract
A piston accumulator has an accumulator housing and a separating piston () guided for longitudinal motion in the accumulator housing. The separating piston separates a liquid side () from a gas side () in the accumulator housing. Liquid unintentionally transitions from the liquid side () to the gas side () despite a piston seal on the separating piston (). By a return device (), the transitioned liquid is at least partially returned from the gas side () of the accumulator housing to the liquid side () of the accumulator housing.
