摘要： A fluid valve which opens for a predetermined time before automatically closing. The valve (101) incorporates a control means including a control chamber (103), a first/inlet passageway (102) and a second/outlet passageway (120). A flow control element (104) is provided in one of the passageways (102) or (120). A biasing means (117) normally biases the valve to a first/closed position (Fig. 3). An activation means (113) is adapted to move the flow control element (104) to an activated position (Fig. 4) wherein flow of fluid is then permitted for a predetermined time.

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.-

摘要： A valve device to control fluid supplied to a tank (123). The valve device includes a fluid inlet (101), a fluid outlet (120) to expel fluid to said tank (123), a valve seat (119), defining an opening through which fluid is adapted to flow from said inlet (101) to said outlet (120), a valve member (107), movable relative to said valve seat (119) between an open and a closed position, and, a control means to operate said valve device. The control means includes a control chamber (103), a fluid passageway (102) between said control chamber (103) and said inlet (101), a flow control element (104) within said fluid passageway (102), a relief valve (106), movable between an open and closed position to selectively expel fluid from said control chamber (103) to a relief port (121), and, a relief valve activation means, to control the operation of said relief valve according to the amount of fluid in said tank (123).
