  • Publication number: 20140060314
    Abstract: A lock valve includes a lock valve body having a bore with a valve spool reciprocatingly received therein. There is a check valve adjacent each end of the bore. Each of the check valves has a check valve member facing the bore and resiliently biased towards a valve seat at each end of the bore. A pressure relief port communicates with the bore near the center thereof and between lands of the valve spool. A pair of spaced-apart grooves are disposed within the spool valve bore. Each groove permits fluid communication past a land of the valve spool when the valve spool is displaced towards one end of the bore by fluid pressure applied to other end of the bore so as to unseat the check valve member adjacent to the one end to the bore and allow pressurized fluid to pass from the one end of the bore, through the groove, and into the relief port.

  • Patent number: 8430702
    Abstract: In some embodiments, a hydraulic steering actuator may be provided. The actuator may include: a cylinder and piston rod reciprocatingly mounted within the cylinder and extending through the cylinder for movement along a piston rod axis; a pair of spaced-apart cylinder arms extending radially outward of the cylinder and a pivot plate extending between the cylinder arms; a pair of support arms which are pivotable about a tilt axis and are connected to opposite ends of the piston rod to allow arcuate movement of the piston rod about the tilt axis while maintaining the piston rod axis parallel to the tilt rod axis; and a tie bar mount disposed on the cylinder and having an aperture extending therethrough for the receiving a connecting member which connects a tie bar to the tie bar mount, wherein the aperture extends axially in a direction substantially perpendicular to the piston rod axis.
