摘要： A valve device comprising a first fluid port (101), a second fluid port (121), a valve seat (119) defining an aperture through which fluid may flow from said first port to said second port, a valve member (107), moveable relative to said valve seat between a seated position and a lifted position. A control chamber (103) is formed at least in part by said valve member, having a first passageway (102) communicating between said control chamber and said first port, and a second passageway (106) communicating between said control chamber and said second port. A control valve (117, 112) is associated with at least one of said passageways to permit fluid flow therethrough, and to thereby urge said valve member into either said seated or lifted position. A restrictor or flow control element (104) is also provided.

摘要： A flow control element adapted to be provided within a substantially longitudinal fluid passageway (105) of a valve device, said flow control element comprising:
a substantially longitudinal element (104) having a cross-sectional area smaller than the cross-sectional area of said passageway (105);
retaining means to retain said element within said passageway (105) whilst permitting automatic movement of said element relative to said passageway (105); and,
a biasing means, such as a spring (120), which permits said element (104) to alter its position within said passageway (105);
such that, said flow control element enables a consistent low flow-rate of fluid through said passageway (105) whilst said automatic movement of said element (104) relative to said passageway (105) cleans and/or clears said passageway (105) from particulate matter such as dirt and/or deposit whilst preventing the ingress of particles which might otherwise clog said passageway (105) and/or flow paths downstream thereof.
