| Number | Title | Issue Date |
| 7055661 | Hydraulic shock absorber with adjusting of shock absorbing type A shock absorber (1) includes a compression chamber (2) in which a piston (3) moves along a path of travel from a near end to a far end. The chamber includes a constant force mode bleed orifice (10) adjacent the far end and a series of pr... | 06/06/2006 |
| 6974001 | Temperature compensating gas spring A gas spring provides an outer cylinder which is partitioned into a multiple of auxiliary volumes. A multiple of temperature compensation valves are located within a piston cylinder which sequentially open or close. As the temperature increases, the temperature comp... | 12/13/2005 |
| 6918851 | Concentric shift system for engaging an interaxle differential lock An interaxle differential is provided which includes a side gear, a clutch gear torsionally locked on a first input shaft and axially slidably mounted thereon and an annular piston mounted in a differential casing for urging the clutch gear into engagement with a si... | 07/19/2005 |
| 6918472 | Arrangement for a piston and cylinder device The hydraulic cylinder or shock absorber arrangement has a cylinder unit limiting an inner space in which a medium in the form of a gas or a liquid is intended to be placed. A forwardly and backwardly movable piston unit is placed such that it can slide within the s... | 07/19/2005 |
| 6467592 | Arrangement for a piston and cylinder device The hydraulic cylinder or shock absorber arrangement has a cylinder unit limiting an inner space in which a medium in the form of a gas or a liquid is intended to be placed. A forwardly and backwardly movable piston unit is placed such that it can slide w... | 10/22/2002 |
| 6327024 | Vibration isolation apparatus for stage A vibration isolation apparatus for preventing shaking and vibration of a stage of an exposure apparatus or the like uses a vibration isolation mount formed of a spring buffer system employing a spring member and a fluid buffer system employing a viscous ... | 12/04/2001 |
| 6161663 | Stroke limiting velocity sensitive valve for a hydraulic lock mechanism Apparatus for preventing the unwanted extension of a hydraulic lock when the lock is subjected to relatively high dynamic loads. The lock includes a hydraulic cylinder having a piston slidably mounted therein. The piston is secured to a piston rod which p... | 12/19/2000 |
| 5038306 | Electronic controller unit for correction of motor vehicle suspension system damping rate sensing errors An electronic controller unit particularly intended for use with intelligent suspension systems for motor vehicles incorporates a microprocessor for enabling operational calibration of each of a plurality of transducers associated therewith in such a mann... | 08/06/1991 |
| 4560041 | Shock absorber unit with temperature compensation The characteristics of a double-tube shock absrober are variable in response to temperature variations as a result of viscosity variations of the damping liquid. In view of compensating for such variations of the damping characteristics the central cavity... | 12/24/1985 |
| 4465166 | Adjustable temperature compensating constant force shock absorber A rectangular metering member with transversal grooves is located with respect to specially formed apertures in a pressure tube of a hydraulic shock absorber to form orifices communicating between the shock absorber pressure tube and a reservoir. The orif... | 08/14/1984 |
