摘要

The system has a gas volume varying device for varying volume of gas in a propellant supplying circuit (4). The gas volume varying device comprises a hydraulic accumulator (8) having variable level of liquid. The accumulator includes a gas supply point and a connection with a conduit of the propellant supplying circuit. A plunger tube of the volume varying device is provided between the gas supply point and the connection for connecting the conduit to the variable level of the hydraulic accumulator, where the plunger tubes comprise a valve. Independent claims are also included for the following: (1) a method for reducing pogo effect (2) a computer medium comprising a set of instructions for performing a method for reducing pogo effect.
