摘要： Described herein is a fluid circuit device. The device incorporates at least one pressure balancing valve located between at least two fluid volumes that can be in a pressure differential arrangement wherein the at least one pressure balancing valve acts to address a pressure differential by opening a fluid volume or volumes to a third pressure equalising volume. In use, the fluid circuit device may in one embodiment be used in an energy absorbtion apparatus.

摘要： A dual tube hydraulic shock absorber includes an inner tube or a cylinder slidably receiving a piston therein, a piston rod secured to the piston and extending out of the cylinder through the upper end thereof, an outer tube surrounding the cylinder to define around the outer periphery of the cylinder an annular reservoir chamber, working liquid filled in the cylinder and in the lower portion of the reservoir chamber, pressurized gas filled in the upper portion of the reservoir chamber, a seal member engaging with the piston rod to seal the shock absorber from the outside, a path connecting the lower portion of the reservoir chamber with the interior of the cylinder, a passage connecting the upper portion of the reservoir chamber with the interior of the cylinder, and check valve means disposed in the passage. The check valve means is formed separately from the seal member and comprises an annular resilient valve member secured to a retaining member formed of a metal.

摘要： A radial partition wall member is fixedly installed in the cylinder cavity of a telescopic suspension unit by positioning the wall member in the cylinder and axially compressing a hollow bead along the edge of the wall member until it spreads radially into frictional clamping engagement with the inner cylinder surface. Application of this method to the construction of two suspension units is described.
