The cavity in the piston plate and the section of the piston (3) inside this cavity have a larger cross-section than an adjoining section of the piston in the direction away from the piston plate. The pump (1) is used to supply fuel to injection systems fo...

A distributing valve (33) is formed as a continuously adjustable valve, which is controlled by a control device based on the operating state of the internal combustion engine and/or the fuel injection system. The valve may be a single-stage three-way valve...

A high-pressure pump (P) for use in a fuel injection system for diesel engines is provided which includes a plunger (21) slidably disposed within a chamber (11) formed in a pump housing (1) to define a pressure chamber (23) whose volume is changed accordin...

A fuel pump comprising a plurality of radially spaced pumping arrangements (10a, 10b, 10c), each of which includes a pumping plunger (20a, 20b, 20c) which is reciprocable within a plunger bore (19a, 19b, 19c) formed in a pump housing (18) under the influen...

A device is described for stabilizing the eccentric ring that moves the pistons of a radial piston pump, such that the two bodies formed by the eccentric ring and the pump housing perform an orbiting motion relative to one another when the eccentric shaft ...
