Abstract: The invention relates to an accumulator comprising: - a housing; - a piston arranged in the housing and movable in an axial direction, wherein the piston seals on the inner wall of the housing and divides the housing in a first fluid tight space and a second space; - a supply opening arranged in the housing and in fluid connection with the first fluid tight space; - urging means for urging the piston towards the supply opening, wherein the urging means are arranged in the second space; - a magnet arranged at the circumference of the piston and adjacent to the housing inner wall, wherein the housing is of a non-ferromagnetic material, such as stainless steel; and - an indicator arranged on the outside of the housing and movable in axial direction, wherein the indicator comprises at least a ferromagnetic part for interaction with the attractive force of the magnet.

Abstract: The invention relates to an accumulator (1) comprising:
- a housing (2);
- a piston (3) arranged in the housing and movable in an axial direction, wherein the piston seals on the inner wall of the housing and divides the housing in a first fluid tight space (5) and a second space (6);
- a supply opening (7) arranged in the housing (2) and in fluid connection with the first fluid tight space (5);
- urging means for urging the piston towards the supply opening, wherein the urging means are arranged in the second space;
- a magnet (8) arranged at the circumference of the piston and adjacent to the housing inner wall, wherein the housing is of a non-ferromagnetic material, such as stainless steel; and
- an indicator (11) arranged on the outside of the housing and movable in axial direction, wherein the indicator comprises at least a ferromagnetic part for interaction with the attractive force of the magnet.
