Abstract (en)
[origin: EP2110597A1] The device (3) has a valve (9) e.g. electromechanic valve, controlled by a signal provided from a pressure sensor (6), and a tube (8) with end connected to the valve, and end connected to a hydraulic duct (2) connected to a hydropneumatic reservoir (1) in a form of flask. A check valve (11) is arranged in the tube to prevent passing of liquid in the tube towards the valve. A check valve (5) is arranged in the duct between the reservoir and the tube. The check valve (5) is closed when a pump (4) mounted on the duct is stopped, where the valve is opened as soon as the pump is started. An independent claim is also included for a method for introducing air into an anti-pressure surge or regulating hydropneumatic reservoir connected to duct.
