## 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.

## Claims

### Claim 1

A nozzle comprising a nozzle inlet, one or more internal channels in fluid communication with the nozzle inlet, and a nozzle outlet in fluid communication with the one or more internal channels, where:
the nozzle inlet is configured to receive a fluid in a first flow direction; and
the internal channels are configured to direct the fluid from the first direction to a second direction substantially different from the first direction.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 5)

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

### Claim 7 (depends on 5)

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

### Claim 8

A nozzle configured to receive a fluid, the nozzle comprising:
an inlet and an outlet; and
a plurality of ribs, 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.

### Claim 9 (depends on 8)

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

### Claim 10 (depends on 8)

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.

### Claim 11 (depends on 8)

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.

### Claim 12 (depends on 8)

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.

### Claim at position 13

13-18. (canceled)

### Claim 19

An apparatus comprising:
a support member comprising a feed chamber; and
a nozzle comprising a nozzle inlet in fluid communication with the feed chamber, a plurality of internal channels in fluid communication with the nozzle inlet, and a nozzle outlet in fluid communication with the internal channels;
where the nozzle inlet is configured to receive a fluid in a first flow direction and the plurality of internal channels are configured to direct the fluid from the first direction to a second direction substantially perpendicular to the first direction.

### Claim 20 (depends on 19)

The apparatus of claim 19, where the support member is configured to be coupled to a spindle housing.

### Claim 21 (depends on 19)

The apparatus of claim 19, further comprising a plurality of ribs between and forming the plurality of internal channels.

### Claim 22 (depends on 19)

The apparatus of claim 19, where the nozzle outlet further comprises a plurality of channel outlets.

### Claim 23

A method of applying a coolant to a grind zone, comprising:
obtaining a system comprising:
a grinding wheel configured to rotate;
a work piece;
a coolant; and
a nozzle comprising a nozzle inlet, a plurality of internal channels in fluid communication with the nozzle inlet, and a nozzle outlet in fluid communication with the plurality of internal channels, where the nozzle inlet is configured to receive the coolant in a first flow direction and the plurality of internal channels are configured to direct the coolant from the first direction to a second direction substantially different from the first direction;
rotating the grinding wheel;
contacting the grinding wheel to the work piece at a grind zone;
supplying the coolant to the nozzle; and
applying the coolant to the grind zone with the nozzle.

### Claim 24
