Fluid transfer guiding/controlling device and application system thereof

A fluid transfer guiding/controlling device comprising a power transfer/distribution unit and a switch member, the power transfer/distribution unit having a first chamber and a second chamber, bypass flow ways being disposed in the first chamber, stop sections being disposed in the second chamber, the number of the stop sections being equal to the number of the bypass flow ways, the stop sections being respectively positioned corresponding to the bypass flow ways, a communication notch being disposed between each two adjacent stop sections, the communication notches being in communication with an outer side of the power transfer/distribution unit, the switch member being disposed in the power transfer/distribution unit, a circumference of the switch member being formed with a first flow guide window and a second flow guide window, the first flow guide window being positioned within a range of the first chamber, the second flow guide window being positioned within a range of the second chamber, whereby the first flow guide window can be switched between the bypass flow ways to communicate with one of the bypass flow ways and the second flow guide window can be switched between the positions of the stop sections, the switch member having an internal flow guide passage in communication with both the first flow guide window and the second flow guide window, when the switch member is switched between different positions, the first flow guide window and the second flow guide window being synchronously switched between different positions along with the switch member, whereby the first flow guide window becomes non-communicated with the bypass flow way originally in communication therewith to communicate with another bypass flow way, at the same time, the second flow guide window is moved from the stop section corresponding to the original bypass flow way to another stop section corresponding to the other bypass flow way, in the switching process, when the switch member passes through the communication notch between the stop sections, part of the fluid in the flow guide passage flowing through the communication notch to discharge to outer side of the power transfer/distribution unit so as to relieve the impact due to abrupt pressure change in the fluid transfer path switching process.
