PCT No. PCT/FR91/00192 Sec. 371 Date Sep. 17, 1992 Sec. 102(e) Date Sep. 17, 1992 PCT Filed Mar. 11, 1991 PCT Pub. No. WO91/14886 PCT Pub. Date Oct. 3, 1991.A device and a process are disclosed for driving a moving surface in a reciprocating motion in a plane, and having a magnitude A2. Two parallelograms are provided, which can be distorted in a plane perpendicular to the plane where the motion is carried out. Each of both parallelograms exhibits two parallel sides, one being common to both parallelograms and driven in a reciprocating motion having a displacement A1=A2/2, the other parallel side of the first parallelogram being stationary and the other parallel side of the second parallelogram being driven in a reciprocating motion having a displacement A2.
