The bushel comprises a plurality of sections for controlling the plurality of fluids in the plurality of fluid circuits respectively. The shell comprises a plurality of fluid inlet and outlet ports that are brought in fluid communication with each other based on angular position of the bushel within the shell, wherein different fluid is selectively supplied in the plurality of fluid circuits based on the angular position of the bushel within the shell. In one example, the bushel comprises a first section, a second section and a third section adapted to control a first fluid, a second fluid and a third fluid respectively, wherein the second section is located between the first section and the third section. The bushel comprises a first fluid inlet for supplying a first fluid and a second fluid to the first section and the second section respectively, and a third fluid inlet for supplying a third fluid to the third section. Since the first fluid and the second fluid are supplied to the first section and the second section respectively through a single fluid inlet, there are some design limitations for the fluid control valve in terms of number of modes, interface adaptation and so on. Particularly, independent control of the first fluid and the second fluid to the first section and the second section respectively is difficult. SUMMARY
[0006] An objective of the present invention is to provide a fluid control valve that alleviates the problems in the prior arts. To be more precise, an objective of the present invention is to reduce the design limitations for the fluid control valve.
