Abstract
Hydraulic valves subjected to a pressure medium in power steering gear include a sleeve journalled on an input shaft, with the sleeve having a torsion bar connected thereto via a driven member. A method of balancing the hydraulic valve includes the steps of inserting the valve into a balanced housing, then determining the neutral position of the input shaft relative to the sleeve. The neutral position is then fixed by rotational connection of the input shaft and torsion bar. The pressure medium used to determine the neutral position is a gaseous medium, and a temporary sealing device adapted to seal the gaseous medium is in contact with the outside surface of the sleeve during determination of the neutral position.
