Abstract

A steering valve includes a housing and a spool disposed inside the housing. The housing includes a top plane and a bottom plane, the top plane including an opening of a first port and the bottom plane including an opening of a second port. The spool includes a top plane including a first and second opening corresponding to a third port and a fourth port, one of which is configured to align with the opening of the first port depending on the orientation of the housing. The spool also includes a bottom plane including a first and second opening corresponding to the third port and fourth port, one of which is configured to align with the opening of the second port depending on the orientation of the housing. The housing is configured to rotate around the spool and wherein the orientation of the housing determines whether the first port is fluidly coupled to the third port via the first opening in the top plane of the spool while the second port is fluidly coupled to the fourth port via the first opening on the bottom plane of the spool or whether the second port is fluidly coupled to the third port via the second opening in the top plane of the spool while the first port is fluidly coupled to the fourth port via the second opening on the bottom plane of the spool.
