| Number | Title | Issue Date |
| 6901689 | Firearm pneumatic counter-recoil modulator and airgun thrust-adjustor An inexpensive generally retrofitable drop-in cartridge-unit of light-weight pneumatic-cylinder design for replacing the conventional metal/compression-spring member housed within the frame of a gun, thereby providing significantly smoother, quiter, more rapid, and ... | 06/07/2005 |
| 5070972 | Vortex valving assembly for a hydraulic damper A vortex valving assembly for a hydraulic damper is adaptable for use in both a piston and a cylinder end. A generator plate includes a plurality of upstanding, arcuate vanes for imparting a vortex to passing fluid and directing the fluid to a central ope... | 12/10/1991 |
| 4515252 | Piston stroke responsive vortex-flow shock absorber A vortex flow hydraulic shock absorber for damping relative displacement of two components comprising a piston provided with a fluid passage therethrough including a pair of vortex chambers formed in a movable valve body disposed between a pair of resilie... | 05/07/1985 |
| 4502575 | Shock absorber A shock absorber has a piston which comprises upper and lower members. The upper and lower members are fixedly assembled to define therein the vortex chamber. The piston has vertically-extending channels on the periphery thereof to define the vertical sec... | 03/05/1985 |
| 4457409 | Vortex shock absorber with absorbing force relief means A shock absorber is provided with a relief valve within a thrusting piston. The relief valve defines a vortex chamber therein and is movable in response to the pressure difference between a high pressure chamber and a lower pressure chamber. The valve is ... | 07/03/1984 |
| 4442925 | Vortex flow hydraulic shock absorber The shock absorber having a piston reciprocatingly disposed in a cylinder and sized small enough to permit a compact construction. The piston defines therein a vortex chamber with a maximum radius. The vortex chamber communicates with fluid chambers defin... | 04/17/1984 |
| 4418802 | Shock absorber A hydraulic shock absorber including a piston disposed within a hollow cylinder in movable position responsive to a shock applied thereto, the piston defining a hollow vortex chamber therein, the vortex chamber being communicated with fluid chambers defin... | 12/06/1983 |
| 4407397 | Shock absorber with pressure-relief mechanism A shock absorber with improved shock absorbing characteristiscs has a piston in which a vortex chamber is formed. The vortex chamber communicates with upper and lower fluid chambers via communication passages. One of the communication passage opens to the... | 10/04/1983 |
| 4335644 | Fluidic recoil buffer for small arms An improved buffer for small arm weapons utilizes a pair of fluid containing reciprocating chambers to attenuate recoil forces by limiting fluid flow in relation to chamber travel between the pair. In the second chamber of the pair a flow control element ... | 06/22/1982 |
