ABSTRACT:
PCT No. PCT/US79/01091 Sec. 371 Date Nov. 30, 1979 Sec. 102(e) Date Nov. 30, 1979 PCT Filed Nov. 30, 1979
Loss of valve opening pressure (VOP) attributed to wear of contacting portions in fuel injection nozzle valves (22) is limited due to provision of a valve tip (38) having a lower portion (38a) which repetitively engages only a lower portion (40a) of a valve seat (40). Advantageous wear of the engaging portions increases the seating area but reduces the effective differential area for fuel pressure to act against, thus reducing the need for increased pressure to open or unseat the valve (22). Increased clearance results in less wear between a reciprocating valve (36) and a cooperating guide (34) which also contributes to reduced (VOP) loss during the life of such nozzle valves (22).
