| 摘要 |
This invention relates to a hydropneumatic piston reservoir (1) with a primary cylinder (2) in which runs a separating piston (12) with free mobility, with the separating piston (12) sealed off circumferentially, with the separating piston (12) inside the primary cylinder (2) separating two pressure chambers (16, 18) from one another. The separating piston (12) has an axial separating piston rod (20) at one end that is sealed off circumferentially from the primary cylinder (2) and is guided as a plunger (22) in a connected secondary cylinder (4) and is subjected to or can be subjected to a pressure medium. The plunger (22) at its free end away from the primary cylinder (2) has a bumper element (24) with a bumper area (28) projecting radially over the outer circumference (26) of the plunger (22).
