Abstract: A high pressure unit fuel injector (1) includes a timing chamber (26) formed between upper (13) and lower (17) plungers of the injector for controlling the timing of injection. A timing chamber relief valve (59) is provided for performing at least one of the functions of (a) draining timing fluid from the timing chamber (26) during an injection stroke responsive to pressure in the timing chamber (26) for maximizing the pressure of fuel in the injection chamber (33) under low speed operating conditions without exceeding a pressure capability of the injector under high speed operating conditions, and (b) for collapsing the timing chamber (26) in a controlled manner at termination of injection so as to prevent secondary injection from occurring. The relief valve structure (59) is wholly formed above the lower plunger (17), preferably within the upper plunger (13) above the timing chamber (26).

Abstract: A cam operated open nozzle fuel injector (12) is provided comprising a reciprocating plunger assembly including an outer plunger (32), an inner plunger (36) and a variable volume timing chamber (52) located between the plungers. A hold down force generating means includes a cam having a hold down cam or ramp portion (106) for maintaining the inner plunger in an innermost position against the inner end of the injector body with a sufficient hold down force during each hold down period throughout injector operation independently of injector train wear. The hold down cam portion operates to move the outer plunger inwardly towards the inner plunger throughout a substantial portion of the hold down period. The hold down cam portion functions to compensate for fuel drainage from the timing chambers so as to maintain a predetermined pressure in the timing chamber corresponding to a desired hold down force.

Abstract: Check valves (500) are incorporated into a fuel injector so as to form a controlling orifice in the system between the solenoid vales which direct fuel to the respective injection and timing chambers of the fuel injector and the chambers themselves. The precision fuel metering capability of the valve (500) is determined by an annular clearance created between the plunger (512) of the valve and the valve body (510) when the valve is in its maximum stroke. For achieving a bi-stable operation of the valve, the ratio of the plunger valve seat (510d) area to the maximum plunger valve (512b) area and the spring (514) are key parameters. The check valves (500) are formed as cartridge type check valves taht can be calibrated outside of the injector prior to the installation thereof.

Abstract: A fuel distributor (10) is provided which is capable of distributing fuel through plural fuel injection lines to the corresponding cylinders of a multi-cylinder internal combustion engine and which includes a distributor housing (12) including a supply inlet passage (32), a plurality of fuel injection outlet passages (34) and a plurality of distributor valves (14) for providing sequential periodic communication between the supply inlet passage (32) and the outlet passages (34). Each distributor valve (14), which may be cam-actuated or solenoid-actuated, is adapted to be placed in an open position allowing fuel flow or a closed position blocking flow through the respective fuel injection outlet passage (34). Each of the distributor valves (14) is adapted to receive a force from the high pressure fuel flowing from the supply inlet passage (32) which urges the distributor valve into the closed position thereby providing an effective seal and minimizing leakage.

Abstract: A pressure responsive spring valve (25) which is able to function at high pressures and temperatures, and can attain a high degree of precision control in a minimum of space, as well as an improved fuel injector (1, 1', 1'') which uses such a spring valve (25). A band-shaped spring valve member (29) is used to reduce the number of parts and the space requirements therefor. The spring valve member (29) is given a configuration which is different from that of the circumferential wall (26b) of the valve body (26) on which it sits, while producing a matching of their surfaces in the area of the outlet ports (28) of the valve body (26).
