Title: Fuel injection pump for internal combustion engine - has operation electronically controlled to suit engine conditions
IPC: F02M41/14
Filed: 1975-11-21
Abstract: The pump (11) is driven by the shaft (15) in the housing (10). Fuel enters through the port (12) and flows into the hole (21) and the annulus (22). The fuel then flows into the hole (24) and through the hole (25) in the shaft (15) and then out through the hole (28) whenever the hole (27) is in line with the tube leading to hole (28). As the shaft rotates the radial pistons (18) with rollers (19) pass over cams in the ring (20) which provide an additional pumping effect to force the fuel through the hole (28). The timing of this pumping effect is controlled by the angular position of the cam ring (20) which is actuated by an electronic control system which responds to the engine operation conditions.

There is a second unit (13) with at least one cam guide (15, 16) against which the piston cylinder units (17, 18, 19) press whilst under pressure in order to produce a relative turning movement between the first and the second unit (12 or 13). A valve system (30) surrounding the shaft (11) is fitted close to the first unit (12) to supply pressure liquid to the inlet of each piston cylinder unit. The valve system is fixed relative to the second unit so that the first unit is turnable relative to the valve system. A pressure device is fitted on the shaft retains the valve system against the first unit in an axial direction. The first unit and the valve system work together with the pressure device so that the forces separating the first unit and the valve system can be transmitted to the shaft and produce a force countering the separating movement on the shaft.
