Patent ID: 8096228

Claim:
A bent axis hydromodule comprising: a hydromodule yoke being rotatable about a trunnion and integrating a first yoke and second yoke wherein the first yoke and the second yoke are fluidly connected; servo pistons and servo piston bores integrated with the hydromodule yoke and positioned on opposite sides of the trunnion wherein the servo piston bores provide fluid communication with the servo pistons; servo piston porting integrated internally within the hydromodule yoke of the hydromodule such that the servo piston porting provides fluid communication between the servo piston bores and servo pistons positioned on opposite sides of the trunnion; wherein the servo pistons are operable to rotate the hydromodule yoke about a trunnion axis; a loop flush spool bore with a loop flush spool therein integrated within the hydromodule yoke in between the first yoke and the second yoke and perpendicular to the trunnion axis; and a control valve in fluid communication with the servo piston porting to control the servo pistons, the control valve being integrated within the hydromodule yoke and being perpendicular to the trunnion axis and perpendicular to the loop flush spool bore, such that distortion of the spool valve and the control valve from hydromodule yoke deflection is reduced.
