Abstract: A fluid transfer guiding/controlling device and an application system thereof. The guiding/controlling device is composed of a power transfer/distribution unit and a switch member. The power transfer/distribution unit has a first chamber and a second chamber. At least one bypass flow ways are disposed in the first chamber. Stop sections are disposed in the second chamber. Communication notches are disposed in adjacency to the stop sections in communication with an outer side. The switch member having an internal flow guide passage and a first flow guide window and a second flow guide window is disposed in the first and second chambers. The first flow guide window is switchable between the bypass flow ways. The second flow guide window is moved from the stop section to pass through a corresponding communication notch, whereby part of the fluid in the flow guide passage flows through the communication notch.

Abstract: A pump with variable suction/discharge amount and a transmission drive device and a driving method thereof. The pump is a rotary vane pump having a vane chamber body. The vane chamber body is composed of a fixed wall member, a movable wall member, a movable vane chamber sleeve and a vane rotor. The vane chamber is extendable/retractable in an axial direction of the vane rotor. At least two pumps are assembled in communication with each other to form a closed loop for the active pump to drive the passive pump. In operation, passive the vane chambers of the active pump and the passive pump are automatically extended/retracted and modulated until the driving force and the load resistance achieve a balanced state passive, the vane chambers and the rotational speeds of the active pump and the passive pump are automatically adjusted to be in inverse proportion to each other.
