Abstract
520,384. Injection pumps. BOSCH GES., R. Oct. 19, 1938, No. 30211. Convention date, Oct. 19, 1937. [Class 102(i)] [Also in Groups XXIX and XXXIV] In a petrol or other injection pump for internal combustion engines in which a cam shaft 3 is located above the oil level 5 in a lubricating oil reservoir 6 and is supplied with oil by means of a delivery pump driven by the injection pump, the delivery pump 9 is disposed within the oil reservoir and is associated with a second delivery pump 10, the inlet end of the suction pipes 11, 15 of both of which are located in said reservoir. The pumps 9, 10 are preferably of the toothed wheel type disposed side by side at one end of the cam shaft 3. Surplus oil from the cam shaft chamber 13 returns through an overflow pipe 14 into the reservoir. The suction pipe 15 of pump 10 extends lower than the suction pipe 11 of the pump 9, and the delivery pipe 18 of pump 10 is connected to a booster or servo-motor 17, the rod 25 of which operates rack means 26 to rotate the pistons 2 of the injection pump 1 and thereby vary its delivery. The servo-motor 17 is controlled by a slide valve 20 which is adjusted by means of a lever 27 pivoted approximately at its mid-point 28 on a rod 29 connected to an aneroid or like pressure-sensitive device 30 which acts against the action of a spring 31. The lower end of the lever 27 may also be operated by a spring-loaded diaphragm 32 in a chamber 35 connected by a pipe 33 to the induction pipe of the engine. The delivery pipe 18 of pump 10 is also connected by a pipe 38 to a leakage barrier 39, 40, 41 for lubricating and sealing each of the pistons 2, any oil trickling upwards escaping through a port 43 back into the reservoir. Alternatively, the pipe 38 may be replaced by a pipe leading to the circulating pump of the lubrication plant of the engine. This latter pipe may also supply the servo-motor, the oil flowing away from which passes into the reservoir, whilst the second delivery pump returns superfluous oil from the reservoir back to the lubricating plant. The reservoir 17 and governor 30 are mounted within the reservoir 6 which is preferably flanged with an open side built on to. the end wall 7 of the injection pump 1.
