Title:
CYLINDER PISTON DEVICE
Document Type and Number:
Japanese Patent JPS588838
Kind Code:
A
Abstract:
In a cylinder piston device a cavity defined within the cylinder contains a pressurized fluid. This pressurized fluid comprises at least one component which within a normal range of operational temperature comprises a gaseous phase and a liquid phase. According to the varying partial volume of the piston rod contained within the cavity, at a predetermined temperature the volume of the liquid phase is varied by condensation or evaporation; the pressure acting onto the piston rod remains however constant. The device may be a shock absorber for vehicles, a spring strut, or non-lockable spring or as shown a lockable spring for height adjustable tables chairs. The fluid with the gaseous and liquid phases may be sulphur hexafluoride, difluoromonochloromethane or butene.
