Abstract: A force transfer arrangement for transferring a force from a rotating camshaft to an output device, that is able to reduce the transversal force on the camshaft. The proposed connection device force transfer arrangement is configured to cause forces to act on the camshaft from substantially opposite directions which effectively produces a resultant force on the camshaft to be close to zero, or at least be reduced compared to prior art force transfer solutions. Thus, the transverse forces on the camshaft and therefore on e.g. bearings supporting the camshaft are reduced thereby the lifetime of the bearings is prolonged.

Abstract: A fuel metering pump assembly for delivering fuel to a combustion chamber of an internal combustion engine has a crankcase, a throttle and at least one cylinder. A housing has a fuel inlet and a fuel outlet, and a metering arrangement is disposed in the housing between the fuel inlet and the fuel outlet. The metering arrangement has a plunger rod movable in a chamber between the fuel inlet and the fuel outlet to control the flow of fuel therefrom, and a movable camshaft is engageable with the plunger rod to selectively deliver fuel from the fuel outlet at a predetermined pressure and volume in response to pulses from the crankcase. A motive device is mounted on the housing in direct engagement with the camshaft. The motive device is responsive to the position of the throttle to move the camshaft relative to the plunger rod so as to vary the fuel delivered from the fuel inlet to the fuel outlet.

Abstract: A centrifugal adjuster for a fuel injection pump governor having a driving part driven at an rpm in synchronism with the engine and having a torsionally elastically coupled flyweight holder guided in a rotational guide. Via a step, beyond a predetermined rotational deflection, the centrifugal adjuster displaces the flyweight holder axially with respect to the driving part, so that a jolt-like stroke effected by means of the step is superimposed on the regulating stroke effected via the flyweights of the centrifugal adjuster whenever the rpm is at a low level, for instance at idling rpm. As a result, a friction that leads to see-sawing of the engine and exhibits pronounced hysteresis is shaken out of the governor.

Abstract: A control arrangement for a fuel-injected supercharged internal engine and, in particular, a diesel engine, with the control arrangement including a fuel injection pump. A control unit is provided for adjusting a fuel output of the fuel injection pump in dependence upon the combustion air delivered to the supercharger. To optimize the measurement of combustion air, the control unit is adapted to be influenced by instantaneous operating parameters such as the rotational speed of the internal combustion engine and rotational speed of the supercharger.

Abstract: A speed governor for fuel injection pumps is proposed having a guide shaft guided in a cam plate to serve as the pivot shaft for a governor lever connecting an adjusting member and a supply quantity control member. The guide shaft is adjustable and guided appropriately by means of an adjusting lever so far as to form a variable-speed governor adapted to varying the full-load and maximum rpm. The cam plate is adjustable by a device by means of an operating parameter acting independently of the speed governor, for instance, the engagement of a cruising or overdrive gear in a manual transmission. Upon rotation of the cam plate, the guide shaft is displaced by a movement-coupling member into a position in which a minimum idling rpm is assured.

Abstract: This invention relates to a device for controlling the rate of delivery of a fuel-injection pump (2) for an internal-combustion engine. The device is composed of a tridimensional planar cam (8) mounted on a slider (40) which is movable axially as a function of the rpm of the pump, the end of stroke depending on the temperature of the engine. The cam (8), moreover, is movable transversely relative to the axis of the slider (40) as a function of a supercharge pressure of the engine.

Abstract: A fuel injection pump is disclosed in which the minimum injection quantity or idling rpm is determined by an arbitrarily adjustable stop. This stop is adjusted via a heatable bimetallic spiral, which acts counter to a spiral spring for the purpose of force compensation.

Abstract: A fuel flow regulation device for a supercharged engine of the type having an injection pump whose piston's bottom position is determined by a moving stop, is disclosed. The fuel flow regulation device consists of a tridimensional cam contacting the stop and movable in an axial and a rotational direction. The axial movement of the cam is provided by a piston rod connected to a pair of pistons, one of which has a smaller diameter than the other by a predetermined amount, in which the pistons are oppositely subjected to engine intake pressure and engine exhaust pressure. The rotational movement of the cam is controlled by a jack subject to the output of a volumetric hydraulic pump actuated by the engine and pumping fluid from the engine cooling system.

Abstract: A fuel injection pump with a metering valve for metering the fuel charge delivered by the pump and a torque cam piston to set a maximum fuel charge limit, the torque cam piston being axially positioned by fuel transfer pressure in accordance with the pump speed and being angularly adjusted manually. Several embodiments of a torque cam profile are shown in which the cam profile is provided by one or more surfaces of revolution and wherein at least one such surface of revolution has an axis inclined to the axis of the piston.

Abstract: A fuel injection pump is disclosed for supercharged Diesel internal combustion engines, in particular, a distributor-type injection pump in which the full-load fuel supply quantity is limited by means of a variable stop, controlled in accordance with rpm and air quantity. The injection pump includes a control apparatus whose control member forms a three-dimensional cam, which is rotated by a charge pressure control element and is displaced in the longitudinal direction by a hydraulic adjustment piston actuated in accordance with the rpm level. The three-dimensional surface of the cam includes protuberances whose profile is picked up and transmitted to a full-load stop of an rpm regulator located in an interior chamber of the injection pump, while the adjustment piston, in abutting relationship with the three-dimensional cam, is actuated for axial movement by the pressure of the fuel located in the interior chamber of the pump, and controlled in accordance with rpm.

Abstract: The invention pertains to apparatus for controlling the quantity of fuel delivery to an engine and engine timing. Several problems with prior apparatus include their high cost and inability to be easily programmed for control purposes, together with their use of complicated electrical controls to meet reliability standards. The inventive solution includes a control rod (16) having a plurality (25,84) of control surfaces of preset shape that determine the maximum quantity of fuel delivery to the engine and engine timing. A plurality (30-36, 40,70) of hydromechanical control circuits axially and rotatably move the control rod (16) in response to engine speed and load. A plurality (18,26,28 and 90-100, 100') of devices control the maximum quantity of fuel delivery and engine timing based on the axial and rotatable positions of the rod (16). The inventive apparatus is used principally to control exhaust emissions from an engine.

Abstract: A diesel engine mechanical governor is disclosed having various novel features including a fuel modulating and maximum and minimum speed controlling cam plate and follower mechanism which connects the governor speed responsive actuating mechanism with the fuel rack actuating means to modify the effect of the manual fuel control means in a predetermined manner. The disclosure also includes novel rocking flyweight mechanism arranged to provide an output force as a function of rotational input shaft speed in which the exponential increase in centrifugal force upon outward rocking of the flyweights is partially offset to provide a more gradual increase in force with a corresponding increase of speed.
