摘要： A fuel injection pump for supplying fuel to the cylinders of the internal combustion engine comprises a housing, a cylindrical sleeve inserted in the housing and provided with a single filling opening communicated with a fuel-feeding passage, and a piston rotatably and reciprocally slidable in the cylindrical sleeve. An end face of the piston encloses with the closing element of the pump a pump operation chamber which is filled with fuel from the filling opening through a number of longitudinal grooves formed in the piston. The longitudinal grooves are in communication with a central relief opening by means of a plurality of radial connecting passages formed in the piston.
