Level adjustment device for vehicles with air springs

Level adjustment device for vehicles with air springs 8a through 8d, by which a vehicle body is furnished with suspension on at least one vehicle axle, which includes the following:a source of compressed air 2, which, for the purpose of filling air springs 8a through 8d, can be connected to air springs 8a through 8d via an air dryer 4, the air dryer 4, for the purpose of filling the air springs, is connected on one side to air springs 8a through 8d through a check valve 6 that is open to air springs 8a through 8d, each air spring 8a through 8d, for the purpose of emptying them, can be connected through the air dryer 4 and through a pneumatically controlled first distribution valve 10 to the atmosphere, wherein the pneumatic control input 38 of this distribution valve 10 is then impinged through a second controllable distribution valve 12 with the pressure in air springs 8a through 8d against a restoring force 50 acting on the pneumatic control input 38, the pneumatic control input 38 of the pneumatically controlled first distribution valve 10, for the purpose of ending the emptying process, can be connected to the atmosphere, wherein the air dryer 4 is connected on the other side to air springs 8a through 8d through a pneumatically controlled third distribution valve 14, wherein the pneumatic control input 44 of this distribution valve is then impinged with the pressure of air springs 8a through 8d against a restoring force 52 acting on the pneumatic control input 44.

Heterogeneous structure for accumulating or dissipating energy, methods of using such a structure and associated devices

PCT No. PCT / FR95 / 01609 Sec. 371 Date Jun. 6, 1997 Sec. 102(e) Date Jun. 6, 1997 PCT Filed Dec. 6, 1995 PCT Pub. No. WO96 / 18040 PCT Pub. Date Jun. 13, 1996The invention relates to a heterogeneous structure for energy accumulation-dissipation (10), the structure being constituted by a porous capillary solid matrix (11) of open capillary porosity and of controlled topology, with capillary passages (12) of varying section and / or mutually interconnected to form labyrinths, and by a liquid (13) surrounding the porous capillary matrix and defining a liquid / solid separation surface, with the matrix (11) being lyophobic relative to said liquid. The area of the separation surface then varies isothermally and reversibly as a function of the external pressure to which the heterogeneous structure (10) is subjected.
