Abstract: A fluid pressure regulating unit, comprises a fluid inlet port, a fluid outlet port, a valve comprising a movable valve part, wherein the movable part comprises at least one fluid pressure balancing means and wherein the at least one pressure balancing means comprises a tapered surface, and a main valve biasing means. The main valve biasing means biases said valve in the direction of an open position. An auxiliary valve biasing means is provided, biasing the valve in the direction of a closed position. Wherein essentially every surface part, being in fluid connection to the fluid inlet port and having a surface normal at least partially in parallel to the moving direction of the moving part of the valve, is balance by a balancing surface part.

Abstract: It is proposed to design a fluid flux regulating unit, comprising a first fluid port, a second fluid port and a valve comprising a movable valve part and at least one fluid pressure balancing means, wherein the fluid pressure balancing means comprises a surface in fluid communication with the first fluid port, which has a surface normal vector at least partially in parallel to the moving direction of the movable valve part.

Abstract: A fluid pressure regulating unit (1, 28, 35, 56, 58), comprises a fluid inlet port (3), a fluid outlet port (4), a valve means (6) and a main valve biasing means (14, 36). The main valve biasing means (14) biases said valve means (6) in the direction of an open position. An auxiliary valve biasing means (26) is provided, biasing the valve means (6) in the direction of a closed position.
