Abstract
A transfer valve includes a spool comprising a first circumferential flow channel at a first axial position of the spool and a second circumferential flow channel at a second axial position of the spool. The first circumferential flow channel and the second circumferential flow channel have different circumferential positions and are defined only partially circumferentially, and a sleeve disposed over the spool. The sleeve includes at least three flow windows defined through the sleeve at an axial position of the sleeve, each flow window having different circumferential positions on the sleeve. The spool is configured to translate within the sleeve between a first position and a second position. The first circumferential flow channel of the spool is configured to fluidly connect a first plurality of the at least three windows in the first position, and the second circumferential flow channel is configured to connect a second plurality of the at least three windows in the second position, wherein the first plurality of windows is different by at least one window from the second plurality of windows.
