ABSTRACT:
A piston-type pressure accumulator for traction slip controlled brake systems, and a switching arrangement provided therewith. An accumulator piston (2) is hydraulically pressurized through a compression spring (1) and slidingly guided within a housing (4). At least one sealing element (27) is provided at the accumulator piston (2) which separates an accumulator chamber (21) from a spring chamber (24). The compression spring (1) is clamped between a first cap (3) directly contacting and surrounding the accumulator piston (2) and a second cap (5) straddling the housing (4) and the first cap (3), the first cap (3) performing a relative movement within the second cap (5) which is sensed by a control switch (7), charging of the accumulator chamber 21 is controlled by energization of a loading valve (8) and pump (9), in turn controlled by the control switch (7).
