Abstract (en)
[origin: US4649879A] An rpm governor for fuel injection pumps of internal combustion engines having two governor levers, namely a first lever engaged by a governor spring and a second lever which actuates the injection quantity control member and is engaged in the opposite direction from the governor spring by an rpm signal transducer, and having an intermediate spring between the two levers, is proposed, in which the intermediate spring is embodied as a spring package of relatively stiffer and softer springs in line with one another, of which the stiffer spring is effective for brief variations in force while the softer spring is contrarily effective for longer-lasting force effects. Structurally, this is attained by means of a hydraulic or pneumatic damping member (dashpot) which receives the softer spring.
