Abstract

In various embodiments, a coolant delivery apparatus is presented. Namely, a coolant delivery apparatus comprises a plurality of internal channels configured to provide coolant to the work face of a grinding wheel.

First claim

What is claimed is:

1. A nozzle comprising a nozzle inlet, one or more internal channels in fluid communication with the nozzle inlet, a nozzle outlet in fluid communication with the one or more internal channels, a proximal wall and a distal wall,
where: the nozzle inlet is configured to receive a fluid in a first flow direction; and the one or more internal channels are configured to direct the fluid from the first direction to a second direction substantially different from the first direction,
where: the internal channels are formed by n number of internal ribs between the nozzle inlet and the nozzle outlet, where n is a positive integer,
where: the nozzle further comprises (n+1) number of internal channels, and
where: (n−1) number of internal channels are formed between adjacent ribs, one internal channel is formed between a rib and the proximal wall, and one internal channel is formed between a rib and the distal wall.

2. The nozzle of claim 1 , where the nozzle is curved about a central axis, and the first flow direction is parallel to the central axis.

3. The nozzle of claim 1 , where the nozzle outlet comprises one or more channel outlets equal in number to the one or more internal channels.

4. The nozzle of claim 1 , further comprising: a support member comprising a feed chamber, where the support member is coupled to the nozzle and the feed chamber is in fluid communication with the nozzle inlet.

5. The nozzle of claim 1 , further comprising a plurality of internal ribs separating the two or more internal channels.

6. The nozzle of claim 5 , where each rib further comprises a lip that curves out of a plane of the rib.

7. The nozzle of claim 5 , where each channel is adjacent to at least one rib.

8. The nozzle of claim 1 , wherein each rib comprising a length; where the length of at least a first rib is less than the length of at least a second rib.

9. The nozzle of claim 8 , where each rib further comprises a lip curving from the plane of the rib.

10. The nozzle of claim 8 , where each rib has a first height and a second height, where the first height is greater than the second height.

11. The nozzle of claim 8 further comprising: a top side comprising a first length; and an under side comprising a second length, where the first length is greater than the second length.

12. The nozzle of claim 8 , further comprising: a support member comprising a feed chamber, where the feed chamber is in fluid communication with the inlet.

13. The nozzle of claim 1 , where the nozzle outlet comprises (n+1) number of channel outlets.

14. The nozzle of claim 1 , where the nozzle comprises an under side and the channel outlets are disposed along the under side.

15. The nozzle of claim 1 , where n is selected from the group comprising 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20.
