Abstract (en)
[origin: WO9103639A1] As is known, a fuel injection pump of the distributor type for internal combustion engines has a piston (20) guided in a cylinder (19) which delimits a working chamber (22) and is driven with a reciprocating and rotary motion by a drive system (16) enclosed in a bath of lubricant. The piston (20) has a distribution drilling (27) which communicates with the working chamber (22) and connects it in turn with injection nozzles on the pressure stroke of the piston (20). The working chamber (22) is filled with fuel via a magnetic valve (21) opened during the intake stroke of the piston (20) and closed during the pressure stroke. In order to increase the filling cross-section during the intake stroke without enlarging the aperture of the magnetic valve (21), there is a relief bore (28) in the piston (20) serving to compensate the forces during the pressure stroke, which communicates with a filler bore (30) connected to the diaphragm (23) store during the intake stroke.
