  • (A) an aligned assembly of two bellows filled with an incompressible fluid, sadi bellows being coaxial and joined by a common partition having located thereon said orifice of restricted section, and said bellows being compressible parallel to their common axis;

    (B) said mobile member comprising a pulley coaxial to said bellows having wound thereon a cable, whereby movement of said cable rotates said pulley;

    (c) cams for alternately compressing ends of said bellows opposite said partition as said pulley rotates for causing said fluid to be passed through said orifice several times in alternate directions during rotation of said pulley.
