초록 ▼

Shock absorber components, such as a radial bypass damper, an anti-cavitation valve (ACV) and an incremental flow metering valve IFMV. The damper is of a continuous, unitary construction with a main hole and auxiliary holes interconnected by passageways. The ACV has openings that angle obliquely relative to entry surfaces of valving shims and extend at an incline continuously through the valving shims. The metering valve linearly regulates flow, substantially independent of piston displacement.

What is claimed is: 1. An apparatus useful to regulate internal pressures in a shock absorber, said shock absorber comprising a fluid-containing cylinder and a working piston capable of moving back and forth within the cylinder in response to external forces, said apparatus comprising: a reservoir for receiving fluid from said cylinder upon being connected thereto; an anti-cavitation valve adapted to reduce fluid cavitation when said reservoir is connected to said cylinder, said fluid cavitation being caused by the movement of the working piston, and said anti-cavitation valve including: a valve body fixedly positioned within said reservoir, said valve body having opposite faces and a plurality of converging passageways that incline in a converging direction from one of the opposite faces to the other and a plurality of diverging passageways that incline in a diverging direction from the one of the opposite faces to the other, the converging and diverging passageways being separated from each other, and valving shims extending over said plurality of converging passageways and said plurality of diverging passageways, each of said valving shims being associated with either said converging passageways or said diverging passageways, each of said valving shims being movable with respect to the valve body in response to pressure within the reservoir, the anti-cavitation valve maintaining pressure between the working piston and the reservoir when the working piston transitions from one direction to another. 2. The apparatus of claim 1 wherein the valve body has circumferential outer walls that are fixedly attached to circumferential walls of a cavity in the reservoir. 3. The apparatus of claim 1 wherein the valving shims include a plurality of plates that are stacked in succession and extend outwardly from the valve body. 4. The apparatus of claim 3 wherein the plurality of plates are of different dimensions. 5. The apparatus of claim 1 wherein the plurality of converging passageways equals a first number of such passageways and wherein the plurality of diverging passageways equals a second number of such passageways, said first and second numbers being different. 6. The apparatus of claim 1 wherein said valving shims include a first number of shims that serve to open and close the converging passageways and a second number of shims that serve to open and close the diverging passageways, said first and second numbers being different. 7. The apparatus of claim 1 wherein the anti-cavitation valve responds to a certain level of pressure within the reservoir while maintaining a positive pressure on the working piston when it transitions from one direction to another. 8. The apparatus of claim 7 wherein the reservoir further includes a gas chamber that responds to pressures within the reservoir above the certain level while maintaining a positive pressure on the working piston as it transitions from one direction to another. 9. The apparatus of claim 8 wherein the anti-cavitation valve is configured to restrict fluid flow in the direction of the gas chamber so as to reduce a pressure buildup in the gas chamber. 10. An apparatus comprising a shock absorber having a fluid containing cylinder and a working piston disposed in the cylinder capable of moving back and forth in response to external forces; a reservoir coupled to the shock absorber for receiving the fluid in a first chamber thereof, said reservoir further including a gas-filled second chamber and a floating piston separating the first and second chambers; and an anti-cavitation valve having a valve body fixedly attached to said remote reservoir between the working piston and he floating pistol and valving shims that move with respect to the valve body to open fluid coupling passageways extending though the valve body in response to pressure created by movement of the working piston, the anti-cavitation valve decreasing the pressure created within the second chamber by movement of the working piston and the anti-cavitation valve and second chamber serving to reduce fluid cavitation caused by movement of the working piston, the anti-cavitation valve maintaining pressure between the working piston and the reservoir when the working piston is in transition between a compression stroke and a rebound stroke. 11. The fluid flow regulator of claim 10 wherein the valve body has circumferential outer walls and said first chamber has circumferential inner walls and said outer walls are fixedly attached to said inner walls. 12. The fluid flow regulator of claim 10 wherein the valve body has opposite faces and a plurality of converging passageways that incline in a converging direction from one of the opposite faces to the other and a plurality of diverging passageways that incline in a diverging direction from the one of the opposite faces to the other, the converging and diverging passageways being separated from each other. 13. The fluid flow regulator of claim 10 wherein the valving shims include a plurality of plates that are stacked in succession and extend outwardly from the valve body. 14. The fluid flow regulator of claim 13 wherein the plurality of plates are of different dimensions. 15. The apparatus of claim 12 wherein the plurality of converging passageways equals a first number of such passageways and wherein the plurality of diverging passageways equals a second number of such passageways, said first and second numbers being different. 16. The apparatus of claim 12 wherein said valving shims include of first number of valving shims that serve to open and close the converging passageways and a second number of valving shims that open and close the diverging passageways, the first and second numbers being different.
