Abstract

Improvements in the construction of hydraulic regulators for fuel injection pumps of the type used in internal combustion engines with a regulation pump whose transport pressure acts on an organ that influences the injection flow and is governed by a distributor valve pressure, which is arranged in a channel that joins the suction side and the pressure side of the regulation pump and works by means of a piston that can move against a recoil spring, driven in its front part by the pressure liquid, and with a throttle valve and which works by means of a plunger that can move against a recoil spring, driven in its front part by the pressure liquid and with a throttle valve that is arranged, on the outlet side, in the channel, in series with the pressure distribution valve, characterized in that the throttle valve is adjustable at will, eg dal throttle, and because the pressure distribution valve causes a pressure that increases with increasing number of revolutions and the rear of its piston is driven by the dominant pressure between the pressure distribution valve and the throttle valve.
