Abstract (en)
[origin: FR2828467A1] The servo actuating rod (7) is connected to a transverse rod (90) which is able to pivot through small angles and has ends which are attached to first and second valves (61,62) in piston (5) seatings (51,52). At rest both valves are closed and the servo exerts no force but when the actuating rod moves left the second valve opens and the piston moves left due to the admitted atmospheric pressure (12) on the inside and a vacuum maintained on outside.
