Abstract

A transfer valve (100) includes a spool (101) comprising a first circumferential flow channel (103) at a first axial position of the spool (101) and a second circumferential flow channel (105) at a second axial position of the spool (101). The first circumferential flow channel (103) and the second circumferential flow channel (105) have different circumferential positions and are defined only partially circumferentially, and a sleeve (107) disposed over the spool (101). The sleeve (107) includes at least three flow windows (109) defined through the sleeve (107) at an axial position of the sleeve (107), each flow window (109) having different circumferential positions on the sleeve (107). The spool (101) is configured to translate within the sleeve (107) between a first position and a second position. The first circumferential flow channel (103) of the spool (101) is configured to fluidly connect a first plurality of the at least three windows (109) in the first position, and the second circumferential flow channel (105) is configured to connect a second plurality of the at least three windows (109) in the second position, wherein the first plurality of windows (109) is different by at least one window from the second plurality of windows (109).
