A retaining ring for a coating material dispenser including a nozzle for the discharge of coating material and a cap having a plurality of orifices arrayed in a spatial orientation with respect to the nozzle to supply a flow of gas or a mixture of gases to aid in dispensing of the coating material from the nozzle. The retaining ring is adapted for retaining the cap on the coating material dispenser with the plurality of orifices in the spatial orientation. The retaining ring includes first and second members. The second member is adapted for coupling to the coating material dispenser. The first member includes a first torque limiting driving member. The second member includes a second torque limiting driven member for engaging the first torque limiting driving member to limit the torque which the second member can apply to the coating material dispenser in response to manipulation of the first member.

What is claimed is: 1. A retaining ring for a coating material dispenser including a nozzle for the discharge of coating material, a cap having a plurality of orifices arrayed in a spatial orientation with respect to the nozzle to supply a flow of gas or a mixture of gases to aid in dispensing of the coating material from the nozzle, the retaining ring including first and second members, the second member adapted for coupling to the coating material dispenser, the first member including at least one first torque limiting driving member, and the second member including at least one second torque limiting driven member for engaging the first torque limiting driving member to limit the torque which the second member can apply to the coating material dispenser in response to manipulation of the first member, wherein the retaining ring for retaining the cap on the coating material dispenser with the plurality of orifices in the spatial orientation. 2. The retaining ring of claim 1 comprising an axis about which it is to be rotated to couple the cap to, and uncouple the cap from, the coating material dispenser, the first torque limiting driving member comprises a driving face which extends generally radially and axially of the axis and a camming face which makes an acute angle with the driving face of the first torque limiting driving member. 3. The retaining ring of claim 2 wherein the second torque limiting driven member comprises a driving face which extends generally radially and axially of the axis and a camming face which makes an acute angle with the driving face of the second torque limiting driven member, the driving faces of the first torque limiting driving member and second torque limiting driven member engaging to drive the retaining ring off the coating material dispenser, and the camming faces of the first torque limiting driving member and second torque limiting driven member engaging to drive the retaining ring onto the coating material dispenser. 4. The retaining ring of claim 1 wherein the first member includes a first portion providing a grip for manipulation of the first member during tightening of the retaining ring onto, and loosening of the retaining ring from, the coating material dispenser, a second portion providing the first torque limiting driving member, and means for coupling first portion nonrotatably to the second portion. 5. The retaining ring of claim 1 including a plurality of first torque limiting driving members. 6. The retaining ring of claim 5 comprising an axis about which it is to be rotated to couple the cap to, and uncouple the cap from, the coating material dispenser, the plurality of first torque limiting driving members being equally angularly spaced around the axis. 7. The retaining ring of claim 1 including a plurality of second torque limiting driven members. 8. The retaining ring of claim 7 comprising an axis about which it is to be rotated to couple the cap to, and uncouple the cap from, the coating material dispenser, the plurality of second torque limiting driven members being equally angularly spaced around the axis. 9. A coating material dispenser including a nozzle for the discharge of coating material, a cap having a plurality of orifices arrayed in a spatial orientation with respect to the nozzle to supply a flow of gas or a mixture of gases to aid in dispensing of the coating material from the nozzle, a retaining ring for retaining the cap on the coating material dispenser with the plurality of orifices in the spatial orientation, the retaining ring including a first member, a second member adapted for coupling to the coating material dispenser, the first member including at least one first torque limiting driving member, and the second member including at least one second torque limiting driven member for engaging the first torque limiting driving member to limit the torque which the second member can apply to the coating material dispenser in response to manipulation of the first member. 10. The coating material dispenser of claim 9 wherein the retaining ring comprises an axis about which it is to be rotated to couple the cap to, and uncouple the cap from, the coating material dispenser, the first torque limiting driving member comprises a driving face which extends generally radially and axially of the axis and a camming face which makes an acute angle with the driving face of the first torque limiting driving member. 11. The coating material dispenser of claim 10 wherein the second torque limiting driven member comprises a driving face which extends generally radially and axially of the axis and a camming face which makes an acute angle with the driving face of the second torque limiting driven member, the driving faces of the first torque limiting driving member and second torque limiting driven member engaging to drive the retaining ring off the coating material dispenser, and the camming faces of the first torque limiting driving member and second torque limiting driven member engaging to drive the retaining ring onto the coating material dispenser. 12. The coating material dispenser of claim 9 wherein the first member includes a first portion providing a grip for manipulation of the first member during tightening and loosening of the retaining ring, a second portion providing the first torque limiting driving member, and means for coupling first portion nonrotatably to the second portion. 13. The coating material dispenser of claim 9 wherein the retaining ring comprises a plurality of first torque limiting driving members. 14. The coating material dispenser of claim 13 wherein the retaining ring comprises an axis about which it is to be rotated to couple the cap to, and uncouple the cap from, the coating material dispenser, the plurality of first torque limiting driving members being equally angularly spaced around the axis. 15. The coating material dispenser of claim 9 wherein the retaining ring comprises a plurality of second torque limiting driven members. 16. The coating material dispenser of claim 15 comprising an axis about which it is to be rotated to couple the cap to, and uncouple the cap from, the coating material dispenser, the plurality of second torque limiting driven members being equally angularly spaced around the axis. 17. The coating material dispenser of claim 9 wherein the plurality of orifices includes a central orifice and a plurality of orifices surrounding the central orifice. 18. The coating material dispenser of claim 17 further including shaping orifices for directing streams of compressed gas or mixture of gases onto the coating material discharged from the nozzle, the shaping orifices being spaced forward from the central orifice and the plurality of orifices surrounding the central orifice. 19. The coating material dispenser of claim 18 wherein the shaping orifices communicate with a supply gallery for the compressed gas or mixture of gases to provide compressed gas or mixture of gases for shaping the coating material discharged from the nozzle. 20. The coating material dispenser of claim 9 including a valve having a somewhat frustoconically shaped portion and a complementarily configured valve seat adjacent the nozzle. 21.
