Abstract: In preferred form, a hydraulic shock absorber piston rod seal of resilient material having an annular collar portion supporting the seal and having radially inwardly projecting end portions on opposite sides of the collar portion which contact the piston rod. One end portion extends axially outward from the shock absorber to prevent the entry of dirt between the piston rod and the seal. The second end portion has a V-shaped cross section adapted to contact the piston rod at a pointed edge to prevent the escape of hydraulic fluid between the piston rod and the seal. An annular garter spring encircles the second end portion to bias the pointed edge of the V-shaped second end portion against the piston rod.

Abstract: An energy absorbing bumper system for automotive vehicles includes a pair of fluid-filled telescopic cylinder units at respective ends of the bumper mounting the same to the vehicle chassis. Variable volume fluid chambers within each unit have the fluid flow therebetween controlled by a floating orifice and metering rod and one of the chambers is bounded by a gas piston urged by a body of compressed gas to force the telescopic mounting unit to a definite extended or normal position wherein the cylinders of the unit are snugly interengaged to resist relative radial displacement in rough road conditions and the like.

Abstract: A viscous fluid clutch including relatively rotatable first and second drive members having a fluid shear space therebetween and which are cooperable with a fluid medium in the shear space to provide a shear-type fluid drive therebetween, an annular reservoir for at times storing the fluid medium, a temperatureresponsive valve for regulating the flow of the fluid medium from the annular reservoir to the fluid shear space, and a baffle wall cooperating with a front wall of one of the drive members to form a narrow annular cooling passage for the fluid medium and further cooperating with an intermediate wall to form the annular reservoir.
