Abstract

Piston pump, especially for fuel injection in engines, in which the liquid is periodically driven in a duct made inside a shaft that rotates in a pump body, this shaft generally being constituted as a distributor, characterized by a metering piston that limits in a cylinder made in the rotating shaft, preferably along its axis, a chamber that is attached to said duct and communicates with a channel on which a braking throttle is provided, and which is arranged in partly in the rotating shaft and partly in the pump body, so that this channel is blocked during the driving times in the duct due to the misalignment of its successive parts, the dosing piston being subjected to an antagonistic force exerted for example by a spring.
