Title: Hose reel swivel

Description:
TECHNICAL FIELD 
     This application claims the benefit of U.S. application Ser. No. 61/169,994, filed Apr. 16, 2009, the contents of which are hereby incorporated by reference. 
    
    
     BACKGROUND ART 
     Existing swivels use o-rings or a stack of multiple leather v-packings. 
     DISCLOSURE OF THE INVENTION 
     The swivel consists of the following: (1) a hardened stainless steel shaft that fluid flows through and the swivel housing rotates around; (2) a carbon steel with zinc plated swivel housing contains the seals and an outlet fitting; (3) a UHMWPE with fluorocarbon o-ring energized seals; (4) threaded brass retainers support the seals and provide a bushing against the shaft; and (5) a retaining clip on end of the shaft. 
     The hose reel swivel uses o-ring energized UHMWPE seals that last longer than prior art o-ring swivels. It also has larger flow passages for high viscosity fluids. It also has less parts than V-packing swivels. 
     These and other objects and advantages of the invention will appear more fully from the following description made in conjunction with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views. 
    
    
     
       BRIEF DESCRIPTION OF DRAWINGS 
         FIG. 1  shows a cross-section of the swivel. 
         FIG. 2  shows an isometric cross-section of the swivel in relation to the hose reel. 
         FIG. 3  shows the hose reel and swivel in relation to a paint sprayer. 
     
    
    
     BEST MODE FOR CARRYING OUT THE INVENTION 
     The hose reel swivel  10  allows the user to coil a hose  12  with a reel  14  and store on a paint sprayer  16 . This eliminates having to coil a hose  12  by hand, which reduces the time to coil the hose  12 , eliminates hose kinks and stores a coiled hose more compactly and securely. 
     The swivel  10  consists of the following: (1) a hardened stainless steel shaft  20  that fluid flows through and the swivel housing  22  rotates around; (2) a carbon steel with zinc plated swivel housing  22  contains the seals  24  and an outlet fitting  26 ; (3) a UHMWPE with fluorocarbon o-ring energized seals  24 ; (4) threaded brass retainers  28  support the seals  24  and provide a bushing against the shaft  20 ; and (5) a retaining clip  30  on end of the shaft  20 . 
     The hose reel swivel  18  uses o-ring energized ultra high molecular weight polyethylene (UHMWPE) seals  24  that last longer than prior art o-ring swivels. It also has larger flow passages  32  for high viscosity fluids. It also has less parts than V-packing swivels. 
     It is contemplated that various changes and modifications may be made to the swivel without departing from the spirit and scope of the invention as defined by the following claims.
