Abstract
A hydraulic fluid control valve (HFCV) configured to recirculate an existing hydraulic fluid from a first hydraulic actuation chamber to a second hydraulic actuation chamber is provided. The HFCV includes a selectively movable spool assembly having an outer annulus, at least one one-way valve arranged within the outer annulus, and an inner fluid chamber configured to receive and deliver the exiting hydraulic fluid to one or both of either a sump or one of the first or second hydraulic actuation chambers. The at least one one-way valve moves in an axial direction and the outer annulus serves as an axial motion stop for the at least one one-way valve.
