Abstract

1395384 Speed governors ROBERT BOSCH GmbH 8 Sept 1972 [9 Sept 1971] 41759/72 Heading G3B [Also in Division F1] A fuel injection pump has a quantity and timing control sleeve valve 26 movable by a centrifugal governor, the governor comprising a first set of weights 33 for causing angular movement of the valve and a second set of weights 34 for causing axial movement of the valve. The weights 33, 34 are mounted in a cage 31 fixed to a gear 30 meshing with a gear 29 on the pump driveshaft 2. As the speed increases the weights 33, 34 progressively move respective co-axial sleeves 35, 36 to the right. Movement of the sleeve 35 is initially resisted by a spring 41 and then also by a spring 42, the springs being connected between levers 37, 38 and a lever 43 positionable by an adjustable stop 46 thereby to determine the tension of the springs 41, 42. Thus with increasing engine speed the lever 37 is turned about a pivot 51 causing an arm 37' to rotate the valve sleeve 26 in a quantity reducing direction. Simultaneously the sleeve 36 turns a spring-loaded lever 48 about a pivot 54 thereby to move the valve sleeve 26 axially in a timing advance direction.
