Abstract: A fluid transfer pump that has a housing, a body portion movable within the housing between a first position and a second position, a gear coupled to the housing, a body cavity defined partially between the body portion and the housing, and an aperture defined in the housing that selectively provides a fluid to the body cavity. When the fluid is applied to the body cavity at or above a pilot pressure, the body portion is in the first position adjacent to the gear and when the fluid is applied to the body cavity at a fluid pressure lower than the pilot pressure, the body portion is in the second position and spaced from the gear.

Abstract: A transfer pump configured to move a hydraulic fluid in a hydraulic fluid management system of a hydraulic system of a vehicle including a transmission. In one embodiment, the transfer pump moves the fluid from a differential case to a hydraulic reservoir coupled to the transmission. The transfer pump is a positive displacement pump including an unloading device, such as a sealing plate, that is resiliently biased against the pump during a normal operation but is moved away from the pump upon the application of a pilot pressure. The result is an open chamber for the pump gears to turn without developing pressure, to thereby reduce parasitic losses.

Abstract: A multi-coupler assembly for a work vehicle includes a first bank of fluid connectors, a second bank of fluid connectors configured to matingly engage the first bank of fluid connectors along a coupling axis, and a coupler mechanism coupled to the first bank of fluid connectors. The coupler mechanism is controllable to bring the second fluid connector bank into mating engagement with the first fluid connector bank. A breakaway feature is integrated into the coupler mechanism. The breakaway feature facilitates controlled disengagement of the first fluid connector bank from the second fluid connector bank along the coupling axis during a breakaway event, such as when an implement inadvertently detaches from the work vehicle. The breakaway feature may permit controlled disengagement of the first and second fluid connector banks without requiring movement of the coupler mechanism.
