Abstract:
A fuel pump device includes a fuel pump in which pressure-generating components in the form of a movable piston movable through a cylinder in the fuel pump together are operable to pressurize the fuel in a chamber exposed to the components to high pressure. To prevent the clearance between the pressure-generating components from increasing with increased heating of the fuel pump and to maintain a predetermined clearance between the piston and the surrounding cylinder, a temperature-regulator maintains a temperature within a predetermined temperature range in a region of the fuel pump which includes the clearance and at least portions of the pressure-generating components.
