A FLUID-PRESSURE ACTUATOR HAVING MEANS TO INDICATE THE POSITION OF THE PISTON AT OR NEAR AN END POSITION

摘要

The means to indicate that the piston (14) is at or near an end position comprises a rod-like member (1) which is actuated by the piston (14). The movement of rod (1) is transformed into a rotary movement by rack (2) and pinion (16). A cam (4) actuates a valve (5) or a microswitch (6).
