Abstract
A fuel injection pump for internal combustion engines of the type having a plunger adapted to be reciprocatingly moved within a barrel to pressurize and deliver a fuel before the establishment of communication between a fuel relief bore formed in the wall of said barrel and a fuel pressurizing chamber, said plunger being adapted to be rotated relatively to said barrel to change the timing of establishment of said communication thereby to adjust the amount of the fuel delivered per stroke of said plunger. Said fuel injection pump is provided with a plunger rotating member coupled to said plunger for rotation therewith. Whereby said plunger can be rotated by merely rotating said plunger rotating member.
