Date Dec. 15, 1988.A distributor fuel injection radial piston pump comprising a distributor piston movable between first and second axial positions to communicate a pump working space with an injection nozzle and to prevent communication between the pump working space with the injection nozzle, a control valve for controlling a quantity of fuel fed to the injection nozzle and movable between open and closed position to communicate the pump working space with the pump interior therethrough in the open position thereof to prevent feeding of fuel to the injection nozzle and blocking communication between the pump working space and the pump interior therethrough in the closing position thereof to provide for feeding fuel to the injection nozzle, and means for preventing excessive feeding of fuel to the nozzle in case of failure of the first control valve to move from the closing position thereof to the open position thereof in response to a predetermined control signal, the preventing means including a control space defined at least partially by the end face of the distributor piston and a second control valve for changing pressure in the control space to move said distributor piston to the second axial position thereof in which feeding of fuel to the injection nozzle is prevented.
