Abstract (en)
[origin: WO2022218665A1] 2. A hydraulic accumulator, in particular a piston accumulator, comprising a separation element (16) which is movably arranged in an accumulator housing (10) and which separates two media chambers (24, 26) from each other, and comprising a distance measuring device for monitoring the position of the separation element (16), is characterized in that the distance measuring device is in the form of a radar device (32) that includes a transmitter (42) emitting a primary signal which, upon at least partial reflection off the separation element (16), generates a secondary signal which, upon reception by a receiver (46), allows a position of the separation element (16) in the accumulator housing (10) to be determined.
