Patent number: 5050558Abstract: In the proposed fuel injection pump of the radial-piston pump type, the fuel injection rate can be controlled exactly by means of an electrically controlled valve which monitors a relief channel (66) of the pump working space (53) and which, by means of its closing time, determines the period of high-pressure injection during the pump-piston feed strokes. In order utilize the total length of the flanks of the drive cams as efficiently as possible, additionally injection adjustment is carried out as a result of the rotation of an essentially stationary part (13, 33) of the cam drive of the pump pistons (37) of the fuel injection pump relative to the rotary-driven part (8,9) of this cam drive. At the same time, on a fuel injection pump with a rotary-driven cam ring (9), there is a separation between a roller-carrying part (13) and a part (33) carrying pistons (37).Type: GrantFiled: November 16, 1987Date of Patent: September 24, 1991Inventors: Andre Brunel, Gerard Duplat, Jean Leblanc

Patent number: 4750462Abstract: A fuel injection apparatus which the termination of the effective pump supply stroke is effected by exposing a relief conduit with the aid of a valve having for instance a control edge, whereupon a highly pressurized fuel flows out via the relief conduit and is directed into a pressure chamber defined by a rear face of a pressure valve closing member. The pressure valve closing member is located in a connection with a fuel injection line that leads from the pump work chamber to the fuel injection valve and is acted upon by a valve spring to effect closing of this injection line. The impact of fuel that reaches the pressure chamber via the releif conduit reinforces a fast closure of the pressure valve closing member at the end of injection, which leads to an abrupt termination of an injection cycle. In addition, or altenatively, the fuel injection valve closing member can also be acted upon by the impact of fuel diversion.Type: GrantFiled: June 11, 1986Date of Patent: June 14, 1988Assignee: Robert Bosch GmbHInventors: Walter Egler, Jean Leblanc, Helmut Pfeifle, Jean Pigeroulet, Francois Rossignol, Dietrich Trachte

Patent number: 4615323Abstract: A pump/nozzle unit having an injection nozzle installed at at least approximately right angles to the longitudinal axis (A) on the pump housing of the piston injeciton pump. The injection pump is supported with a support face, which embodies its most extreme axial extension, on a support bearing located on the cylinder head of the engine. The support face is embodied by an outwardly pointing end face of a counterpart piston which is inserted into the pump cylinder in an extension of the longitudinal axis (A) and, with an inner end face, seals off the pump work chamber in a pressure-tight manner. As a result, the pumping forces resulting from the fuel which is placed under pressure in the pump work chamber are kept from affecting the pump housing and intercepted at a location on the cylinder head which is remote from a receiving bore for the injection nozzle.Type: GrantFiled: March 29, 1985Date of Patent: October 7, 1986Assignee: Robert Bosch GmbHInventors: Jean LeBlanc, Francois Rossignol

Patent number: 4604980Abstract: A fuel injection pump is proposed in which the fuel metering takes place during the intake stroke of the pump pistons via a fuel supply line in which a switching valve is mounted, which is opened upon the onset of the intake stroke of the pump pistons, closes in the course of this intake stroke and with this closing point also determines the injection onset upon the ensuing supply stroke of the pump pistons. The quantity of fuel to be injected is then limited by means of a pump-guided control edge, which is disposed on an annular slide provided on a free end of the distributor of the fuel injection pump; when a first control opening on the distributor which communicates with the pump work chamber coincides with a second control opening on the annular slide, the pump work chamber is relieved. The diversion or gradual shutoff point is controlled in the course of the compression stroke movement of the pump pistons by means of the relative rotation of the working point of the second control opening.Type: GrantFiled: March 8, 1985Date of Patent: August 12, 1986Assignee: Robert Bosch GmbHInventor: Jean Leblanc

Patent number: 4574759Abstract: A fuel injection pump in which for the purpose of controlling the injection quantity and in particular to determine the onset and end of injection, a hydraulically actuatable piston slide is provided, which controls a connection between the pump work chamber and a fuel supply line or the fuel supply container. The control is effected via two magnetic valves acting in opposite directions, by means of which two different, high control pressures acting upon the piston slide can be exerted. The control pressures are made available either with a single pressure control valve and by blocking off the relief of the supply side of the fuel supply pump, or else by means of two pressure control valves.Type: GrantFiled: November 13, 1984Date of Patent: March 11, 1986Assignee: Robert Bosch GmbHInventor: Jean Leblanc
