ABSTRACT:
An improved steering apparatus includes a piston and cylinder type motor having a hollow piston rod extending out of one end of a motor cylinder. Since the piston rod extends out of only one end of the motor cylinder, the working area on the head end of the piston is greater than the working area in the rod end of the piston. The head end working area is exposed to fluid pressure during turns in one direction and the rod end working area is exposed to fluid pressure during turns in the opposite direction. A compensator chamber is provided in the hollow piston rod. The compensator chamber has a working area on the rod end of the piston. The compensator chamber working area is exposed to fluid pressure during turns in both directions. The size of the compensator chamber working area is equal to the cross sectional area of a tubular wall of the piston rod. Since the compensator chamber working area is the same size as the cross sectional area of the piston rod and is on the rod end of the piston, exposing the compensator chamber working area to fluid pressure during turns in both directions tends to equalize the steering forces in both directions.
