          Appeal No. 96-4164                                                          
          Application 08/467,295                                                      





                                 DECISION ON APPEAL                                   
                    This is a decision on appeal from the examiner's final            
          rejection of claims 14, 22 and 23.  Claims 1 through 12 have been           
          canceled.  Claims 13 and 15 through 21 stand allowed.  Claim 24,            
          the only other claim pending in the application, was objected to,           
          but has been indicated to be allowable if rewritten in independ-            
          ent form.                                                                   


                    Appellant's invention relates to a method of operating            
          a reversing valve, such as that found in a vapor compression                
          refrigeration system (e.g., a heat pump system).  Of importance             
          to appellant is that the reversing valve be so constructed and              
          arranged that the valve member “is relieved from system fluid               
          pressure forcing it against its seat as it moves between alterna-           
          tive flow directing positions along a path of travel by which it            
          is separated from its seat, thereby avoiding substantial friction           
          forces opposing valve member motion and enabling use of simple,             
          low force valve actuators” (specification, page 4, lines 17-23).            
          Independent claim 14 is representative of the subject matter on
