摘要： The device's user acts on integral control members of a cylinder (6) moving in avertical column (1). A fixed tube (12) enters the cylinder (6). A compressor (16) canproduce a pressure inside the tube (12) and the cylinder (6). A counterforce according tothe value of this pressure and the surface of the tube section (12) opposes thedisplacement towards the bottom of the cylinder (6). This counteracting force issubstantially constant, the volume of the portion of the tube (12) engaged in the
chamber (6) is negligible compared to the total volume thereof. Thus, contrary to what isthe case with the physical training apparatus of this type in which the counterforce isproduced by a spring or by moving a piston within a cylinder, this force remains constantduring movement of the movable member on which acts the user of the apparatus.
