Patent GB-314800-A (GB)
IPC: F02D1/00
Filed: 1929-06-26
Abstract: 314,800. Motorenfabrik Deutz Akt.- Ges., (Assignees of Astfalck, F. M.). July 2, 1928, [Convention date]. Cam-actuated pumps; stroke, varying; timing- devices.-In engines working with airless injection of liquid fuel and adapted for motor vehicles, a pump forcing a liquid or air past a throttled opening is used to retard the time of fuel injection automatically as the speed decreases and vice versa. Fig. 1 shows the fuel-pump cam b which, in addition to being adjustable axially by a governor-actuated lever f so as to vary the length of the pump stroke, is also adjustable angularly by a lever g controlled by a gear pump d<1> which forces oil or air through a throttled by-pass q. As the engine speed increases, pressure is built up under a piston m<1>, which actuates the lever g to cause an earlier injection. The lever g slides axially a sleeve e connected to the cam by a pin i and inclined slot k, so that the cam is adjusted angularly. The throttle q is adjusted by a hand wheel p, but may also be adjusted in dependence on the engine speed by the connections shown in dotted lines between the piston rod o and a lever on the throttle screw.
