Abstract

A poppet valve (100) is provided according to the invention. The poppet valve (100) includes a valve body (101), a valve poppet (135) movable in the valve body (101), and at least one non-symmetric orifice (110) in the valve body (101). The valve poppet (135) is configured to move to a substantially blocking position with regard to the at least one non-symmetric orifice (110) and configured to move away from the at least one non-symmetric orifice (110).

Claims

1. A poppet valve (100), comprising:

a valve body (101);

a valve poppet (135) movable in the valve body (101); and

at least one non-symmetric orifice (110) in the valve body (101), with the valve poppet (135) being configured to move to a substantially blocking position with regard to the at least one non-symmetric orifice (110) and configured to move away from the at least one non-symmetric orifice (110).

2. The poppet valve (100) of claim 1, with the at least one non-symmetric valve orifice (110) including a length L_O that is greater than a width W_O.

3. The poppet valve (100) of claim 1, with the at least one non-symmetric valve orifice (110) comprising two or more non-symmetric orifices (110).

4. The poppet valve (100) of claim 1, with the at least one non-symmetric orifice (110) further comprising:

an upper non-symmetric orifice (110b); and

a lower non-symmetric orifice (110a).

5. The poppet valve (100) of claim 1, with the at least one non-symmetric orifice (110) further comprising:

two or more upper non-symmetric orifices (110b); and

two or more lower non-symmetric orifices (110a).

6. A poppet valve (100), comprising:

a valve body (101);

a valve poppet (135) movable in the valve body (101) between at least a substantially closed position and an open position; and

two or more valve orifices (110) in the valve body (101), with the valve poppet (135) being configured to move to a substantially blocking position with regard to the two or more valve orifices (110) in the substantially closed position and configured to move away from the two or more valve orifices (110) in the open position.

7. The poppet valve (100) of claim 6, with the two or more valve orifices (110) comprising two or more non-symmetric valve orifices (110).

8. The poppet valve (100) of claim 6, with the two or more valve orifices (110) comprising two or more non-symmetric valve orifices (110), with an orifice of the two or more valve orifices (110) including a length L_O that is greater than a width W_O.

9. The poppet valve (100) of claim 6, with the two or more valve orifices (110) further comprising:

two or more upper valve orifices (110b); and

two or more lower valve orifices (110a).

10. The poppet valve (100) of claim 6, with the two or more valve orifices (110) further comprising:

two or more upper non-symmetric valve orifices (110b); and

two or more lower non-symmetric valve orifices (110a).

11. A poppet valve (100), comprising:

a valve body (101);

a valve poppet (135) movable in the valve body (101);

at least one non-symmetric valve orifice (110) in the valve body (101), with the valve poppet (135) being configured to move to a substantially blocking position with regard to the at least one non-symmetric orifice (110) and configured to move away from the at least one non-symmetric orifice (110); and

a valve actuation member (129) coupled to the valve poppet (135), with the valve actuation member (129) passing through the at least one non-symmetric valve orifice (110).

12. The poppet valve (100) of claim 11, with the at least one non-symmetric valve orifice (110) including a length L_O that is greater than a width W_O.

13. The poppet valve (100) of claim 11, with the at least one non-symmetric valve orifice (110) comprising two or more non-symmetric orifices (110).

14. The poppet valve (100) of claim 11, with the at least one non-symmetric valve orifice (110) further comprising:

an upper non-symmetric valve orifice (110b); and

a lower non-symmetric valve orifice (110a.

15. The poppet valve (100) of claim 11, with the at least one non-symmetric valve orifice (110) further comprising:

two or more upper non-symmetric valve orifices (110b); and

two or more lower non-symmetric valve orifices (110a).
