Abstract: The vehicle comprises a chassis including a substantially flat frame for fixing the means for holding the front and rear wheels (or front and rear axles), and a body connected to the chassis by elastic elements adapted to filter noise and vibration. The frame of the chassis is thin and has high self-rigidity in its plane. The body is arranged so as to withstand, without notable deformation, torsion forces around the longitudinal direction of the vehicle and flexion forces under vertical load. The elastic linking elements between the body and the chassis are arranged to prevent, in practice, any vertical relative displacement and to enable slight relative longitudinal movement between the chassis and the body. The assembly is such that the body, fixed to the chassis opposes buckling of the latter.

Abstract: An internal combustion engine comprises a cylinder having a horizontal axis, one end of the cylinder being formed as a combustion chamber and the other end opening into a crankcase receiving a lubricating atmosphere. A piston slidable in the cylinder has a space therein communicating with the crankcase. The piston is formed with grooves of rectangular cross-section with a base and a pair of transverse surfaces. A scraper groove furthest from the combustion chamber receives a scraper ring and has orifices in its base communicating with the piston space, the other sealing grooves receiving piston rings, annular gaps between the piston and cylinder being left on each side of the piston and scraper rings. The annular gaps are placed in continuous communication with the groove bases by at least one recess on each transverse surface of a sealing groove and by at least one recess on that transverse surface of the scraper groove which is nearest the combustion chamber.

Abstract: An electrically operated valve comprises a distributor having a slide operative to selectively place a fluid actuated device in communication with a source of pressurised fluid, or with a fluid outlet. The slide is actuated by an electrodynamic motor in response to a control signal, whereby the fluid pressure in the device is dependent on the signal.
