VEHICLE HYDRAULIC STEERING MECHANISM Russian patent published in 1997 - IPC

FIELD: transport engineering; vehicle steering systems. SUBSTANCE: steering wheel is connected with pump through inlet line, with hydraulic tank through return line, with actuating hydraulic cylinder, safety valve and antishock device of operating lines by two operating lines. Steering hydraulic mechanism differs from steering mechanisms now in use in the following: antishock device is made in form of antishock valve consisting of shutoff member resting on free end of safety valve spring and seat whose diameter is smaller than that of safety valve seat, and two check valves, input of antishock valve being connected with outputs of check valves whose inputs are connected with operating lines.
