Abstract
A desmodromic mechanism exhibits reciprocating motion of a pair of cam followers driven by a single cam. The mechanism is useful in a fuel pump that pressurizes a liquid for delivery to a fuel rail of a combustion engine. A desmodromic lever is symmetric about its rotational axis and maintains continuous contact between cam lobes and cam followers for the entirety of each rotational cycle. The mechanism is particularly useful in multi-piston pumps required to deliver higher than normal volumes of liquid fuel, as is the case with low energy density alternatives to diesel fuel.
