APPARATUS TO DETECT DIRECTION DEFECTS IN THE EFFORT PRODUCED BY A COIL SPRING ON A PISTON SLIDING IN A SHEATH

摘要

the invention relates to a device to eliminate defectsorientation of the force produced by a spring (1) in a spiraltogether with a sheath (3) and a piston (2) mounted slidingin the sheath (3), the spring (1) is disposed in the piston coaxialement(2) in its base (11, 13) of substantially opposed effortson the frame (3) and a piston (2). there is provided arotulante link (18, 23) between the spherical core (13) of the springthe piston screw (1) and (2), this rotulante centered onthe axis (17) of the piston (2).
