ABSTRACT:
Mechanically programmable hydraulic linear positioner providing a primemover with the ability to assume and maintain accurately any of an arbitrary number of preselected programmed positions, and to quickly reposition the load from one such preselected detent position to another detent position upon command. A Hall effect magnetic field sensor detects load position and generates command signals directly controlling a proportional hydraulic valve. Rotary and manual positioning applications are described.
