Title: Speed governor for diesel engines
IPC: F02D1/10
Filed: 1980-05-06
Abstract: The invention provides a speed governor which adjusts the quantity of fuel supplied by the injection pump for all engine speeds and comprises a sleeve (2) axially displaceable in accordance with engine speed which includes a driver member (6) preloaded by an extension spring (7) urging it towards a stop (8) on the sleeve (2). When engine speed drops below a pre-set idling speed the sleeve (2) moves in one direction and drives one end (14) of a cranked lever (10), pivotally connected to the throttle lever (12), so that control linkage (15, 19) of the injection pump increases fuel delivery. When engine speed rises above idling the sleeve (2) moves in the opposite direction and the linkage (15, 19) moves accordingly to reduce the quantity of fuel injected. The governor includes a cam plate (22) which is connected to the sleeve (2) by a driver (21) and which functions to control the fuel supply and thus the engine speed outside the idling range. This is achieved through a compensation lever (24) and a roller (26) mounted thereon which is applied to compensation (31) and maximum (30) speed profile of the cam (22) by a spring (28). In supercharged engines the compensation lever (24) may be adjusted by a pressure sensitive device (39) or a second cam plate (40) and lever (36) may be provided. <IMAGE>
