摘要

The accumulator charging valve arrangement (1) comprises a high-pressure terminal (12) and an accumulator port (11). A seat valve (20) is arranged between the high pressure terminal and a low-pressure chamber (14). The seat valve comprises a poppet valve piston (21) formed with a sealing surface that is biased against a sealing edge into a closed position in which communication between the high pressure terminal and the low-pressure chamber is interrupted.
