LIMITADOR DE CARRERA CONTINUAMENTE AJUSTABLE PARA POSICIONADOR HIDRAULICO.

摘要

The stroke length in a positioner (10) of the type having a piston rod (14) movable through a cylinder (12) can be preset through a continuous range of adjustment. A first detent element (22) provided at the end of the cylinder engages another detent element (66) positionable along the rod to limit stroke length. Spacing between the two detents is continuously adjustable by rotatation of a threaded sleeve (50) coaxial with the rod. Once installed in a recliner seat or the like, the device is secure against accidental changes in the stroke setting.
