Abstract (en)
A piston accumulator (40) for damping two fluid systems is provided. The piston accumulator (40) comprises a cylinder (42), a first port (44) for a fluid system to be damped, which is disposed at one end of the cylinder (42), and a first piston (52), which is contained in a sealed manner and slidably in the cylinder (42). Furthermore, the piston accumulator (40) comprises a second port (46) for a second fluid system to be damped, which is disposed at the other end of the cylinder (42), and a second piston (54), which is contained in the cylinder (42) in a sealed manner and is slideable between the first piston (52) and the second port (46). A first damping volume (60), formed between the first (52) and the second piston (54), is or can be filled with fluid, preferably gas. The accumulator further comprises a third piston (68), which is contained in the cylinder (42) in a sealed manner and is slideable between the second piston (54) and the second port (46), wherein a second damping volume (70), formed between the second (54) and the third (68) piston, is or can be filled with fluid.
