ABSTRACT:
A frictionless hydraulic damper including a cylinder having end walls mounting the opposite ends of a shaft with a clearance in labyrinth seals, bellows seals between each end wall and the portions of the shaft extending beyond each end wall, a piston head on the shaft within the cylinder, hydraulic fluid in the cylinder and in both bellows seals, an orifice construction located relative to the piston head for permitting flow of hydraulic fluid past the piston head to produce damping, and a conduit in the shaft for effecting communication between the two bellows. The damper as described above also functions as a snubber by including a valve construction which selectively closes the orifice construction.
