  • Piston accumulator
    Patent number: 12241482
    Abstract: A piston accumulator has an accumulator housing and a separating piston (8) guided for longitudinal motion in the accumulator housing. The separating piston separates a liquid side (4) from a gas side (10) in the accumulator housing. Liquid unintentionally transitions from the liquid side (4) to the gas side (10) despite a piston seal on the separating piston (8). By a return device (28), the transitioned liquid is at least partially returned from the gas side (10) of the accumulator housing to the liquid side (4) of the accumulator housing.
    Type: Grant
    Filed: November 29, 2022
    Date of Patent: March 4, 2025
    Assignee: HYDAC TECHNOLOGY GMBH

  • PISTON ACCUMULATOR
    Publication number: 20200362883
    Abstract: A piston accumulator, having an accumulator housing and a separating piston (8) guided for longitudinal motion therein, wherein said separating piston separates a liquid side (4) from a gas side (10) in the accumulator housing, and wherein liquid unintentionally transitions from the liquid side (4) to the gas side (10) despite a piston seal on the separating piston (8), is characterized in that, by means of a return device (28) the transitioned liquid is at least partially returned from the gas side (10) of the accumulator housing to the liquid side (4) of the latter.
