Abstract

A damper includes an inner tube elongated along an axis, a piston slidably disposed in the inner tube, and an outer tube surrounding the inner tube. The inner tube and outer tube define a fluid chamber therebetween. The damper includes and intake assembly in the fluid chamber. The intake assembly includes a unitary support ring and pair of fulcrum spacers, a support post fixed to and extending along the axis away from the unitary support ring and pair of fulcrum spacers, and a valve ring supported by the support post. The valve ring defines an orifice. A valve disc is supported by the support post between the valve ring and the unitary support ring and pair of fulcrum spacers. The valve disc covers the orifice of the valve ring.

Claims (35)

1 . A damper, comprising:

an inner tube elongated along an axis;

a piston slidably disposed in the inner tube;

an outer tube surrounding the inner tube, the inner tube and outer tube defining a fluid chamber therebetween; and

an intake assembly in the fluid chamber, the intake assembly including:

a unitary support ring and pair of fulcrum spacers,

a support post fixed to and extending along the axis away from the unitary support ring and pair of fulcrum spacers,

a valve ring supported by the support post, the valve ring defining an orifice, and

a valve disc supported by the support post between the valve ring and the unitary support ring and pair of fulcrum spacers, the valve disc covering the orifice of the valve ring.

2 . The damper of claim 1 , further comprising a second support ring, a second valve ring defining a second orifice, and a second valve disc covering the second orifice of the second valve ring, both the second valve ring and the second valve disc supported by the support post between the second support ring and the valve ring.

3 . The damper of claim 2 , wherein the outer tube defines an intake orifice between the valve ring and the second valve ring along the axis.

4 . The damper of claim 2 , further comprising a second pair of second fulcrum spacers unitary with the second support ring.

5 . The damper of claim 4 , wherein the support post extends from one fulcrum spacer of the pair of fulcrum spacers to one second fulcrum spacer of the second pair of second fulcrum spacers.

6 . The damper of claim 5 , further comprising a second support post extending from another fulcrum spacer of the pair of fulcrum spacers to another second fulcrum spacer of the second pair of second fulcrum spacers.

7 . The damper of claim 1 , wherein the pair of fulcrum spacers are spaced from each other 180-degrees about the support ring.

8 . The damper of claim 1 , wherein the pair of fulcrum spacers are thicker than the support ring along the axis.

9 . An intake assembly supportable between an inner tube and an outer tube of a damper, the intake assembly comprising:

a unitary support ring and pair of fulcrum spacers;

a second support ring;

a support post fixed to and extending away from the unitary support ring and pair of fulcrum spacers to the second support ring;

a valve ring supported by the support post, the valve ring defining an orifice; and

a valve disc supported by the support post between the valve ring and the unitary support ring and pair of fulcrum spacers, the valve disc covering the orifice of the valve ring.

10 . The intake assembly of claim 9 , further comprising a second valve ring defining a second orifice and a second valve disc covering the second orifice of the second valve ring, both the second valve ring and the second valve disc supported by the support post between the second support ring and the valve ring.

11 . The intake assembly of claim 10 , wherein the valve ring is spaced from the second valve ring.

12 . The intake assembly of claim 11 , further comprising a clamping ring between the valve ring and the second valve ring.

13 . The intake assembly of claim 10 , further comprising a second pair of second fulcrum spacers unitary with the second support ring.

14 . The intake assembly of claim 13 , wherein the support post extends from one fulcrum spacer of the pair of fulcrum spacers to one second fulcrum spacer of the second pair of second fulcrum spacers.

15 . The intake assembly of claim 14 , further comprising a second support post extending from another fulcrum spacer of the pair of fulcrum spacers to another second fulcrum spacer of the second pair of second fulcrum spacers.

16 . The intake assembly of claim 9 , wherein the pair of fulcrum spacers are spaced from each other 180-degrees about the support ring.

17 . The intake assembly of claim 9 , wherein the pair of fulcrum spacers are thicker than the support ring.

18 . A method, comprising:

installing a first valve disc, a first valve ring, a clamping ring, a second ring, and a second valve disc onto a pair of posts attached to a unitary support ring and pair of fulcrum spacers; and

then securing a unitary second support ring and second pair of fulcrum spacers to the posts opposite the unitary support ring and pair of fulcrum spacers to provide a intake assembly.

19 . The method of claim 18 , further comprising installing the intake assembly onto an inner tube of a damper.

20 . The method of claim 19 , further comprising securing the intake assembly to the inner tube by compressing the first valve disc, the first valve ring, the clamping ring, the second ring, and the second valve disc between the unitary support ring and pair of fulcrum spacers and the unitary second support ring and second pair of fulcrum spacers.
