  • Publication number: 20230193747
    Abstract: The present disclosure provides a method and system for supplemental processing of recorded historical data in real time to fill in gaps of lost data. A user who may be monitoring the data from human interfaces can immediately recognize an issue, quickly change one or more settings for parameters (including changing one or more of the parameters), and replay for reprocessing the recorded data to provide a revised output that can catch up to the processing of later current data without needing to halt operations. In at least one field of use, the invention can eliminate the need for restarting a complete drilling process to resynchronize the surface system when the system is not able to demodulate a valid bitstream, saving time and maintaining high drilling efficiency.

  • Patent number: 4376432
    Abstract: A fuel injection pump is provided with an improved spill control mechanism to accurately supply a desired fuel charge to an internal combustion engine. The fuel pump includes a rotor having a charge pump for pressurizing measured charges of fuel for delivery to the engine and a cam ring adapted to rotatably receive the rotor and to actuate the charge pump upon rotation of the rotor. The cam ring is angularly adjustable to control the timing of the pressurized fuel delivery to the engine. A spill collar mounted adjacent to the cam ring and adapted to rotatably receive the rotor includes a spill port for diverting fuel flow from the charge pump upon registration of a spill passage in the rotor with the spill port in the collar. A pivotal crank mounted on the cam ring and engageable with the spill collar is provided for adjusting the angular position of the spill collar relative to the cam ring to control the amount of fuel diverted from the charge pump.

  • Patent number: 4255097
    Abstract: This invention relates to fuel injection pumps of the type employed for supplying measured charges of fuel to the nozzles of an associated internal combustion engine. More particularly, the invention relates to such fuel pumps of the rotary distributor type having pumping plungers which are slidably mounted in radial bores of a rotary distributor and are surrounded by a generally circular cam ring having pairs of inwardly directed cam lobes which actuate pairs of pumping plungers inwardly simultaneously for pressurizing the charge of fuel between the plungers to a high pressure.The subject invention overcomes the above problems by angularly spacing a pair of pumping plungers and the cooperating cam lobes as required for the specific engine application and avoids the undesired side loading by creating a hydraulic counterbalancing force which automatically changes as the side loading created by the reaction forces between the cam lobes and the pumping plungers changes with speed and rate of delivery of fuel.

  • Patent number: 4224916
    Abstract: A fuel injection pump having a mechanically adjustable servo valve for controlling the timing of the pumping event is disclosed. A pivoted lever has one end which engages the spring seat of a timing control plunger servo valve which is also subjected to a speed related hydraulic signal and another end which engages a cam clamped on the throttle shaft to pivot the lever according to the rotational position of the shaft. The profile of the cam is such as to retard the timing of the pumping stroke when the charge delivered by the pump is increased so that pressure built up in the pump is delayed and injection pressure is reached at a substantially constant crankshaft angle regardless of variations in speed and load on the engine. The mechanism is failsafe since it cannot interfere with the movement of the throttle shaft to reduce fuel delivery.

  • Patent number: 4149831
    Abstract: A supply pump comprising a body having an inlet and an outlet both in fluid communication with an interior region of the body which contains two pistons positioned to reciprocate coaxially and which define three variable volume chambers, one between the two pistons and in fluid communication with the inlet, a second between one piston and the outlet and a third between the other piston and the outlet. The pistons have different working areas, and the piston of larger area carries a check valve which allows fluid flow from the chamber between the pistons to the chamber between the larger piston and the outlet. A regulating spring acts between the body and the smaller piston to urge both pistons against a mechanical drive means including a reciprocable rod carried by a tappet contacting a driven cam. During each forward and reverse stroke of the pistons in response to rotation of the cam, supply fluid is drawn into the pump through the inlet and forced out of the pump through the outlet.

  • Patent number: 4083345
    Abstract: A rotary distributor fuel injection pump is provided with a main high pressure pumping chamber and an auxiliary high pressure pumping chamber which have a common inlet and outlet passage. The pumping plungers in said pumping chambers operate in unison to generate simultaneous high pressure pulsed charges of fuel within the pumping chambers. Both pumping chambers are connected to deliver their high pressure outputs simultaneously to the output passage for delivery sequentially to each of the cylinders of an associated engine. A speed responsive valve controls the delivery of the output from the auxiliary pumping chamber to the common outlet passage and isolates the auxiliary chamber from the common inlet and outlet passage without impairing the connection of the main pumping chamber with the common inlet and outlet passage when engine speed reaches a predetermined level.

  • Patent number: 4052971
    Abstract: A liquid fuel injection pump for supplying timed charges of fuel to an engine by timed pumping strokes includes an adjustable timing mechanism for changing the timing of the pumping strokes. The timing mechanism includes an advance piston which is variably positionable in response to two different hydraulic control pressures. A speed related control pressure operates a servo mechanism associated with the advance piston to provide a component of speed advance. The reference position of a servo spring associated with the servo mechanism is varied by the second control pressure acting against a piston which mounts the spring and which is biased to a position of relatively advanced timing, thereby to add a component of advance which modifies or supplements the speed advance.

  • Patent number: 3999529
    Abstract: A multiple plunger fuel injection pump includes a pair of axially positionable interconnected control sleeves encircling each plunger for controlling the quantity and timing of fuel delivered by the plunger. Speed and load response actuators are operative to control the axial positioning of each sleeve of each pair of control sleeves. Adjustment means are provided for separately adjusting, during operation of the injection pump, the axial positioning of each sleeve to balance the timing and quantity of fuel delivered by each plunger with respect to the other plungers.

  • Patent number: 3968779
    Abstract: A fuel injection pump with a control system for regulating the quantity and timing of the delivery of fuel to an associated engine is disclosed. In the control system, three pistons, slidably mounted in parallel bores, are provided. One of the pistons is powered so that it assumes an axial position indicative of engine speed. A second piston is powered to assume an axial position indicative of the quantity of fuel being delivered by the pump. The first and second pistons are each provided with a cam surface, and cam followers controlled thereby interconnect these pistons with the third piston to control the axial position of the third piston and the timing of delivery of fuel by the pump.

  • Patent number: 3938911
    Abstract: There is disclosed a rotary distributor type liquid fuel injection pump for delivering measured charges of fuel under high pressure sequentially to the cylinders of an associated engine in timed relation therewith. The pump includes a movable metering valve for regulating the quantity of fuel in the charges. The metering valve also controls a normally closed bypass port which is opened by the metering valve as the metering valve approaches its closed position to continue the circulation of cool fuel from the supply tank through the pump whenever the metering valve is closed as during the downhill coasting of the vehicle on which the pump is mounted.
