Abstract
In one form of the invention, a rotatable and axially slidable plunger mounted within a fixed cylindrical plunger barrel forms with the barrel the casing bore and a spring biased electromagnetically driven axially slidable cut off sleeve, a dash pot chamber including a narrow radial gap between the cut off barrel and the pump casing body. The high pressure cut-off fuel may be directed to the chamber. Alternatively, the cut-off fuel may be directed to impact a deflector to produce an axial force modulating axial shift of the sleeve.
