Abstract
A device (1; 101) for controlling the flow of a fluid through a conduit (2; 102; 402; 602; 702) from an upstream side (3; 103; 703) to a downstream side (5; 105; 405; 605; 705), the device (1; 101) comprising: a valve having a valve member (14; 114; 414; 514; 614) arranged to move reciprocally selectively to open and close one or more valve apertures (10; 110; 412; 512; 611, 612), thereby controlling flow of the fluid from the upstream side (3; 103; 703) to the downstream side (5; 105; 405; 605; 705); and means for introducing a reference pressure (24; 124; 324; 424; 524; 624); wherein said valve member (14; 114; 414; 514; 614) is acted on by the pressure of the downstream side (5; 105; 405; 605; 705) and the reference pressure so as to be moved by the difference between said pressures.
Claims23
A device for controlling the flow of a fluid through a conduit from an upstream side to a downstream side, the device comprising:
- a valve having a valve member arranged to move reciprocally to selectively open and close at least one valve aperture, thereby controlling flow of the fluid from the upstream side to the downstream side;
- and
- an arrangement for introducing a reference pressure;
- wherein said valve member is acted on by the pressure of the downstream side and the reference pressure so as to be moved by the difference between said pressures.
