With the above described fuel injection pump of rotary type according to this invention, there are afforded such an improved fuel injection pump of rotary type wherein constant fuel injection operation is assured by virtue of the following advantageous features that upon change of the rotating number of the face cam shaft, there occurs control of fuel injection operation by causing the metering sleeve therein to be moved axially within the barrel of the pump by function of centrifugal forces rendered on the mechanical governor, thus maintaining the fuel injection volume per stroke of each plunger incorporated therewithin; upon change of the suction pressure of the engine there also occurs fuel injection control by causing the metering sleeve to be slided axially by function of the booster so as to change the fulcrum position or the basic operating point of the governor, thus relatively controlling the fuel injection volume irrespective of the changes of rotating number of the pump. The control of the valves 24 and 26 is effected by means of an electronic control system to be described, which receives a demand signal from the driver of the vehicle of which the engine forms part and determines from signals supplied to it, the instant at which the valve 24 should be opened and the timing of delivery of fuel so that it can control the operation of the valve 26. It is a further object of this invention to provide an improved rotary type fuel injection pump wherein there is provided lubrication between the metering sleeve and the barrel of the fuel pump so as to effectively prevent a heat seizure or burning therebetween. fuel injection pump replacement. of 56. 4, the metering cam 98 is in a position to close the metering port 100 of the passageway 42. Let's look at each type in more detail: 9 Different Types of Rotary Pumps are: Vane Pumps. The signal from the transducer 29 (B) is similar to that provided by transducer 27 and whilst it can occur at the same time, before or after the signal produced by the transducer 27, it is the example, arranged to always occur after the signal provided by the transducer 27. Now, the plunger pump 22 is taken for example for description. Rotary Distributor Diesel Fuel Injection Pump Asme Pdf When people should go to the ebook stores, search opening by shop, shelf by shelf, it is essentially problematic. In general, however, in such a metering mechanism as described above, if there increases the velocity of such transversal movement of the cam across the metering orifice, there exists such a specific trend to increase the fuel injection volume per stroke of each plunger, therefore it is now necessary to control in a secondary manner such increase in the fuel injection volume. The pump described above whilst it requires additional components, these are in general of an electrical nature. Prices are indicative only and may vary by country, with changes to the cost of raw materials and exchange rates. During this time the inlet port 23 is out of register with the inlet passages and fuel is delivered to one combustion space of the associated engine. Such mechanical vibrations are liable to be immediately transmitted to the metering sleeve unless any cushioning member is provided therebetween, which vibrations would cause directly or indirectly heat seizure or burning between the metering sleeve and the barrel of the fuel injection pump of the conventional construction.
