ABSTRACT:
A fluid pressure servo motor comprises a body having two operatively independent fluid chambers each chamber having therein a piston means movable in response to a fluid pressure differential so as to alter in use a two condition device from one to the other of said two conditions. The two piston means each have a lost motion means connection with the device to allow idle return of the pistons on cessation of the pressure differential. The two chambers and their respective pistons are co-axial and the pistons work in opposition to each other, one piston being fixed to a stirrup which bridges the other piston and acts in use against the two condition device, while allowing said other piston to move independently of the stirrup. Also disclosed is a vehicle door locking system incorporating servo motors as described.
