Damper assembly
A damper assembly includes a cylinder defining a chamber. The damper assembly includes a body supported by the cylinder and having a first surface and a second surface opposite the first surface. The body defines a passage extending from the first surface to the second surface. One of the first surface or the second surface define a slope at the passage. The damper assembly includes a check disc at the slope, the check disc selectively restricting fluid flow through the passage.
1. A damper assembly, comprising:
a cylinder defining a chamber;
a body supported by the cylinder and having a first surface and a second surface opposite the first surface, the body defining a passage in fluid communication with the chamber and extending from the first surface to the second surface;
an orifice disc at the first surface, the orifice disc defining an orifice open in a radial direction;
a check disc movable in a first direction from an unflexed position spaced from the orifice disc toward the body to a flexed position on the orifice disc to selectively restrict fluid flow through the passage in the first direction; and
a spring urging the check disc toward the body, the spring including a base and a plurality of arms extending circumferentially and axially from the base.
2. The damper assembly of claim 1 , further comprising a second orifice disc at the second surface, and a second check disc movable in a second direction from an unflexed position spaced from the second orifice disc toward the body to a flexed position on the second orifice disc to selectively restrict fluid flow through the passage in the second direction, and wherein the second direction is opposite the first direction.
3. The damper assembly of claim 1 , wherein the orifice extends to a radial outer edge of the orifice disc.
4. The damper assembly of claim 3 , wherein a radial outer edge of the check disc in the unflexed position is spaced from the radial outer edge of the orifice disc and the radial outer edge of the check disc in the flexed position abuts the radial outer edge of the orifice disc.
5. The damper assembly of claim 3 , further comprising a fulcrum disc between the orifice disc and the check disc.
6. The damper assembly of claim 5 , wherein the fulcrum disc abuts the orifice disc and the check disc.
7. The damper assembly of claim 6 , wherein a radially outer edge of the fulcrum disc is radially inward of the orifice of the orifice disc.
8. The damper assembly of claim 1 , wherein the orifice disc extends radially across the passage.
9. The damper assembly of claim 8 , wherein the orifice disc extends completely across the passage.
10. The damper assembly of claim 1 , wherein the base abuts the body and the plurality of arms abut the check disc.
11. The damper assembly of claim 1 , wherein the body is a piston.
12. The damper assembly of claim 1 , wherein the check disc in the unflex position permits axial and radial fluid flow through the orifice and the check disc in the flexed position inhibits axial fluid flow and permits radial fluid flow through the orifice.
13. A damper assembly, comprising:
a cylinder defining a chamber;
a body supported by the cylinder and having a first surface and a second surface opposite the first surface, the body defining a passage in fluid communication with the chamber and extending from the first surface to the second surface;
an orifice disc at the first surface, the orifice disc defining an orifice open in a radial direction;
a check disc movable in a first direction from an unflexed position that permits axial and radial fluid flow through the orifice of the orifice disc toward the body to a flexed position that inhibits axial fluid flow and permits radial fluid flow through the orifice; and
a spring urging the check disc toward the body, the spring including a base and a plurality of arms extending circumferentially and axially from the base.
14. The damper assembly of claim 13 , wherein the orifice extends to a radial outer edge of the orifice disc.
15. The damper assembly of claim 14 , wherein a radial outer edge of the check disc in the unflexed position is spaced from the radial outer edge of the orifice disc and the radial outer edge of the check disc in the flexed position abuts the radial outer edge of the orifice disc.
16. The damper assembly of claim 14 , further comprising a fulcrum disc between the orifice disc and the check disc.
17. The damper assembly of claim 16 , wherein the fulcrum disc abuts the orifice disc and the check disc.
18. The damper assembly of claim 17 , wherein a radially outer edge of the fulcrum disc is radially inward of the orifice of the orifice disc.
