Abstract
Pressure volume regulator () for control of supply and pressure of barrier fluid for pumps and compressors subsea, comprising an inlet () for barrier fluid at an inlet pressure, a first outlet () and a second outlet (), the inlet pressure is higher than the first outlet pressure that is higher than the second outlet pressure. The pressure volume regulator is distinctive in that the inlet and the second outlet are interlocked between a movable longitudinal interlock member () with valve elements operatively arranged at either end, the length of the interlock member plus said valve elements is shorter than the distance between an open-close valve mechanism of the inlet and an open-close valve mechanism of the second outlet.
