摘要： A hydraulically actuated fuel pump (1) for an internal combustion engine has a pump piston (39), which is driven forwards in a delivery stroke by means of an actuator piston (36). Between each injection sequence the pump piston (39) is returned to a fixed starting position by the action of the fuel pressure on the end surface (61, 62) of the pump piston in the pump chamber (52). The delivery volume of the fuel pump is electronically controlled by the supply of hydraulic fluid to the pressure chamber being cut off by the control valve (11) at the moment when the pump piston has delivered the desired volume. The pump cylinder (25) and the actuator cylinder (24) are separate units, which are mutually separated by an intermediate spacing member (26).

摘要： An internal combustion engine (1) has hydraulically driven exhaust valves (13) and fuel pumps (18). The hydraulic drives are controlled by means of a computer (16) and electrically activated positioning means (64) setting a spool in a spool valve. If the electronic control of the engine fails, the spool movement may be controlled by a first piston (41) on which the pressure in a hydraulic hose or conduit (48) acts, said conduit extending to a second piston (44) which may follow a cam (26) on a rotating camshaft. The hydraulically driven cylinder members (13, 14, 18) associated with each of the engine cylinders are mounted at the pertaining cylinder, whereas the camshaft (23) independently of the positioning of the cylinder members is disposed at an appropriate shaft drive, such as the crankshaft (11). The cam shaft has a very short length and small mass and may for instance be disposed at one end of the engine.

摘要： A spool valve (22) controls a hydraulic drive, such as a drive for a fuel pump (18) in an internal combustion engine, in which the hydraulic drive comprises a driving piston (34) journalled in a hydraulic cylinder (33) which through a flow passage (31) is in communication with the spool valve. The spool (38) may occupy a position in which the flow passage is connected with a high-pressure source (29) and another position in which the flow passage is connected with a low-pressure port (30). The spool is settable by means of a positioning means (23) electrically activated by a control unit (16) which determines intended positions of the spool and for a movable part (56) in the positioning member. The movable part has windings (51) positioned in a magnetic field in a slit (60) which is oblong in the longitudinal direction of the spool. A sensor (66) signalizes the actual position of the movable part to the control unit (16). The movable part and the spool (38) are attached to each other so that the spool valve follows the movements of the movable part (56). The control unit (16) supplies current to the windings if the actual position of the movable part differs from the intended position.
