A variable device for regulating the outlet pressure of a fluid from a valve body, includes a pressure-sensing chamber having a wall formed by a resilient self-restoring diaphragm which is responsive to pressure in the chamber. A valve element connected to the diaphragm controls flow into the chamber. Increased pressure in the chamber decreases the flow into the chamber and decreasing pressure increases flow whereby fluid flow out from the chamber is maintained at a desired pressure. The outlet pressure is adjusted by deflecting the diaphragm in a direction to open the valve while permitting a section of the diaphragm connected to the valve member to remain responsive to the pressure in the chamber. An adjustment cover is provided to adjustably deflect the diaphragm and includes a catch mechanism to allow adjustment of the fluid outlet pressures and also retain the device at a desired value. An indicator arrangement may be provided to visually indicate the fluid outlet pressure.

U.S. patent application Ser. No. 09/816,956, filed Mar. 23, 2001. the product held by said surface to be transferred on substantially an entire surface of the lips of the user. 3. A device for applying a product to at least one of the user's lips, the device comprising: a product to be applied to at least one of the user's lips; and a support comprising at least one portion formed of an elastically deformable material, said at least one portion of the support comprising at least one application surface and being configured to be loaded with the product, wherein the support has a size and shape permitting the support to be placed between spaced apart lips of a user, and wherein the support is configured such that when at least one of the user's spaced apart lips is moved toward the other lip to compress the support, said at least a portion of the support elastically deforms, said at least one application surface assumes a contour of at least one of the lips, and said at least a portion of the support transfers the loaded product to one of the lips contacting the at least one application surface. 4. The device of claim 3, wherein said at least one portion of the support is impregnated with the product. 5. The device of claim 4, wherein the support is configured to transfer the product to substantially the entire surface of said at least one of the lips. 6. The device of claim 4, wherein the product is a lip make-up product. 7. The device of claim 3, wherein the at least one application surface comprises two application faces. 8. The device of claim 7, wherein the two application faces comprise a first application face configured to contact one of the lips and a second application face configured to contact the other lip. 9. The device of claim 3, further comprising a gripping element associated with the support. 10. The device of claim 9, wherein the support is mounted on the gripping element. 11. The device of claim 3, wherein the at least one application face comprises flocking. 12. The device of claim 3, wherein said at least a portion of the support comprises elastically compressible foam material. 13. The device of claim 3, further comprising a reservoir and a mirror provided on the reservoir. 14. The device of claim 3, further comprising a reservoir, wherein the support is mounted to rotate with respect to the reservoir. 15. The device of claim 3, wherein the support has a disk-like configuration. 16. A device for applying a material to at least one of a user's lips, the device comprising: a reservoir containing a material to be applied to a user's lips; and a support comprising at least one portion formed of a deformable material, said at least one portion of the support comprising at least one application surface and being configured to be loaded with the material, wherein the support has a size and shape permitting the support to be placed between spaced apart lips of a user, and wherein the support is configured such that when at least one of the user's spaced apart lips is moved toward the other lip to compress the support, said at least one portion of the support deforms and transfers the material to substantially the entire surface of at least one of the lips contacting said at least one application surface. 17. The device of claim 16, wherein the reservoir contains a material chosen from a lip make-up material and a lip care material. 18.
