Abstract: A pump and associated method including the steps of pre-metering successive quantities of fuel from a reservoir to a positive displacement transfer pump, then actuating the transfer pump to raise the pressure of the successive quantities of fuel by at least about 100 psi, preferably 200-300 psi. Each quantity of fuel which was pressurized in the transfer pump, is delivered to a high pressure pumping chamber so that each pumping bore receives a certain, i.e., predetermined, charge of fuel within a first time interval. A plurality of plungers in the respective pumping bores are then simultaneously actuated to increase the pressure in the pumping chamber to the desired high pressure, preferably at least about 15,000 psi, within a second time interval, and to discharge the quantity of fuel through a high pressure discharge valve. The second time interval is of longer duration than the first time interval. As a result, the necessary quantity of fuel can be delivered to the pumping chamber in a relatively short time period. Therefore, each pumping plunger can be actuated by a dual rate cam profile over a relatively long time period such that at steady state the actuating occurs only along a relatively shallow slope of the cam profile, whereas when acceleration is required, the actuation can occur more quickly, along a steeper profile, before continuing along the relatively shallow profile.
Abstract translation: 一种泵和相关方法，包括以下步骤：将来自储存器的连续量的燃料预先计量到正排量输送泵，然后致动所述输送泵以将连续量的燃料的压力提高至少约100psi，优选为200 -300psi。 在输送泵中被加压的每一量的燃料被输送到高压泵送室，使得每个泵送孔在第一时间间隔内接收一定的即预定的燃料。 然后在相应的泵送孔中的多个柱塞被同时致动，以在第二时间间隔内将泵送室中的压力增加到期望的高压，优选至少约15,000psi，并且将燃料量排出高 压力放电阀。 第二时间间隔比第一时间间隔更长的持续时间。 因此，必要量的燃料可以在较短时间内被输送到泵送室。 因此，每个泵送柱塞可以在相对较长的时间周期内通过双速率凸轮轮廓致动，使得在稳定状态下，致动仅沿着凸轮轮廓的相对较浅的斜面发生，而当需要加速时，致动可以发生更多 迅速地，沿着更陡峭的轮廓，然后继续沿着相对较浅的轮廓。

Abstract: A fuel pump for supplying fuel to an engine includes a rotary drive shaft (12) having an enlarged portion (18) through which the rotary part of the pump is driven. The pump also has an annular cam ring (17) which is angularly adjustable within the pump housing to vary the timing of fuel delivery. The pump includes a transducer (31) having pole pieces (33, 34) which are located in close proximity to the elongated portion (18) of the drive shaft. The pole pieces form part of a magnetic circuit including a magnet and the pole piece (33) and the adjacent surface of the portion (18) are shaped so that the flux in the magnetic circuit varies in a cyclic manner as the shaft rotates. The pole pieces and magnet are mounted on the cam ring (17) and the transducer includes a former (37) carried by the housing of the pump and upon which is wound a winding. The former surrounds a part of the magnetic circuit and the former and the part of the magnetic circuit are shaped so as to allow angular movement of the cam ring.

Abstract: A rotary distributor fuel pumping apparatus includes a distributor member (12) defining a pair of bores (13) in which are slidable pumping plungers (14). The outer ends of the plungers are engaged by cam followers (27, 28) which engage cam lobes to urge the plungers inwardly as the distributor member is rotated. The fuel displaced from the bores is supplied to an outlet port (17) and a spill valve (22) is provided to control the amount of fuel supplied. The bores are completely filled with fuel and in order to control the initial rate of fuel delivery at least one plunger is moved inwardly before the others. In one arrangement the cam follower of that plunger is housed in an inclined slot (26) and the other cam followers housed in straight slots in a part (23) surrounding the distributor member and the cam followers are movable axially in the slots so that the one cam follower moves angularly relative to the others and therefore is moved inwardly in advance of the others.

Abstract: A lengthwise drilling (37) in the rotary distributor (2) connects a high-pressure chamber (11) with a control position (39) in it. The drilling is formed in the distributor from one end and then sealed off from the outside by a plug (45). The latter is cylindrical, being inserted in a transverse drilling (46) intersecting the lengthwise one and at least of the same diameter. The plug is prevented from moving in the drilling, in which it is typically a press-fit. Alternatively, it can be glued in place. There can also be a component (29) enclosing the rotor at the transverse drilling and forming a wall preventing the plug sliding out. The component can contain a recess, while the plug is longer than its drilling, protruding from it to form a driving dog engaging in the recess.

Abstract: PURPOSE: To permit complex injection rate by a composite oil sending rate characteristic performed by the whole of cams and to effect smooth pumping operation by a method wherein a plurality of cams, having simple cam profiles, are provided and the cam profiles of a part of the cams are made different.
CONSTITUTION: A cam 22d is more advanced than the other cams, therefore, a plunger 2c is lifted at first to compress fuel in a high pressure chamber 6 and sends it by pressure into the injection valve of a corresponding cylinder through a delivery port 7 thereby injecting and supplying the fuel into a combustion chamber. Initial injection is finished at the compression upper dead point of the cam 22d. Thereafter, the plungers 2d, 2a, 2b to which the remaining cams 22aW 22c are corresponding, are lifted simultaneously to effect the pressure sending of the fuel for the later period of injection of a large injection rate. Upon a stage in which the later period injection is effected, the fuel of initial injection has been brought into a condition that it is readily ignited, therefore, the ignition lag of the fuel of later period injection is shortened and slow combustion is effected thereby reducing noise of combustion.
