The invention concerns a machine which converts an excess pressure created into motion, without the excess pressure having to be renewed substantially, in accordance with patent application P 3607468.3 and supplementary patent application P 3619539.1. In the present invention, the slope or curve 16, 16a down which the roller 15 of the piston 13 rolls is steeper than the slant of the pressure chamber floor 4 when the piston 13 is returned. In such a design, the piston 13 is moved back into the pressure chamber 1 in at least four stages. <IMAGE>
