ABSTRACT:
An improved fuel rack mounting arrangement, particularly for use in an in-line pump, is structured to reduce actuating forces. The fuel rack is supported by a pair of lever arms pivotally connected thereto at longitudinally spaced pivot axes. Each lever arm is also pivotally connected to the pump housing at separate pivot axes. The orientation and positioning of the various pivots are such as to afford longitudinal reciprocation of the rack in response to actuation of one of the levers about its pivot axis by which it is connected to the housing. The actuation may be provided by a stepper motor acting on an extension of the lever. Each lever may include an integral pivot pin and a locking mechanism for captured pivotal mounting of the rack.
