Oscillating air motor reversing control - with piston motion control system and pivoted linkages which are spring biased

摘要

In an addition to 2161323, an oscillating air motor with automatic control by piston motion of the confirmed air input to the cylinder, has linkages which at one end are pivotable on one of the axes of an attached lever pair, the other ends are attached in a pivoted fashion to a tripping pin. The piston valve control rod unit is via a reversing device movable between two end stop positions, and is secured into these two positions by a recessed retainer device, the device is spring biased.
