Beschreibung
Zusammenfassung:	A fluid controller (15a) in a multiple-input hydrostatic power steering system includes a check valve assembly (101), having a first fluid passage (111), defining a check valve seat (105) and a check valve (103) operably associated therewith, in fluid communication with a second fluid passage (109), with the second fluid passage (109) being in fluid communication with a return port (25a). In the left (L) and right (R) operating positions, return flow can flow from the interior region (114) of the valve (27), through the first fluid passage (111), past the check valve (103), and through the second fluid passage (109) to the return port (25a). In the neutral position (N), pressurized fluid can flow from an inlet port (19a) to the return port (25a), with the check valve (103) preventing fluid from flowing through the first fluid passage (111) and into the interior region (114) of the valve (27).
