Abstract
A hydraulic positioner of the type having a piston movable in a hydraulic cylinder and a valve actuatable for releasing the piston for movement in the chamber is provided with a continuously adjustable mechanism for limiting the stroke of the piston. The cylinder and the stroke limiter share a common tubular housing which is partitioned to define the hydraulic chamber, thereby simplifying the device.
