Description

PATENTKRAV 1. Doseringssystem for cylindersmøreolie til store dieselmotorer, for eksempel i skibsmotorer, med en forsyningsledning samt en returledning, der er forsynet med hver sin ventil (3,27), og som er forbundet med en central forsyningspumpe, samt et antal indsprøjtningsenheder, der modsvarer antal smøresteder i hver cylinder, og som er forbundet med nævnte ledninger, hver af hvilke enheder omfatter: -en injektionsdyse pr. smørested for indsprøjtning af i det mindste en kompakt smøreoliestråle på cylinderoverfladen i en tilknyttet cylinder, idet en forstøvning af smøreoliestrålen gennem injektionsdysen i videst mulige omfang undgås, -et stempel (1), der er anbragt i en bageste del af en dysestav, samt -en styrbar motor (37), der via en skrue (33,) er i anlæg mod stemplet (1) for derved at kunne justere stemplets (1) pumpeslaglængde/position, og hvilket system tillige omfatter -en central computer til styring af ventilerne (3,27) samt den styrbare motor (37). 2. System ifølge krav 1, kendetegnet ved, at dysen omfatter en cylindrisk dysestav (2) til indmontering gennem et hul (4) i cylindervæggen, hvilken dysestav har en central passage (14) for et nåleventillegeme (18), som er fjederbelastet i udadgående retning for lukning af et indre ventilsæde i en dyseudmunding af dysestaven, samt en anden passage (24) for styret tilbringning af trykolie til et forreste trykkammer (30), hvori trykolien kan udøve både en tilbagepresning af nåleventillegemet for åbning af det indre ventilsæde og en overtryksindsprøjtning af olie gennem den derved åbnede dyse, indtil olietrykket sænkes for effektiv lukning af nåleventilen, hvorhos nævnte anden passage udgøres af en kanal (24) imellem en ydre rørcylindrisk dysestav (2) og et deri centralt placeret gennemføringsrør (22) for central optagelse af nåleventillegemet (18). 3. System ifølge krav 1 eller 2, kendetegnet ved, at stemplet (1) er belastet af en fjeder (Γ), som presser stemplet mod et olietilførselsrum (5), når systemet er trykløst. 4. System ifølge krav 1, 2 eller 3, kendetegnet ved, at der i dysen (11) har en ydre skråtstillet dysekanal (12). 5. System ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at injektionsdysen, og den styrbare motor er anbragt koncentrisk om en fælles akse. 6. System ifølge et hvilket som helst af kravene 2-5, kendetegnet ved, at fjederen (32), der påvirker nåleventillegemet, er i anlæg mod en længdeforskydelig glider (34), hvis slaglængde/position er bestemt af den styrbare motor (37). 7. System ifølge krav 6, kendetegnet ved, at glideren (34) er rotationsmæssigt fastholdt af et styr (35). 8. System ifølge et hvilket som helst af kravene 2-7, kendetegnet ved, at fjederen (32), der påvirker nåleventillegemet, har en forspænding svarende til det ønskede lukketryk for ventilnålen (18).PATENT REQUIREMENTS 1. Dosing system for cylinder lubricating oil for large diesel engines, for example in marine engines, with a supply line and a return line, each with its own valve (3.27), connected to a central supply pump, as well as a number of injection units which corresponds to the number of lubrication points in each cylinder and connected to said wires, each of which units comprise: - one injection nozzle per lubrication site for injecting at least one compact lubricating oil jet onto the cylinder surface of an associated cylinder, avoiding atomization of the lubricating oil jet through the injection nozzle as far as possible, a piston (1) disposed in a rear portion of a nozzle rod, and - a controllable motor (37) abutting against the piston (1) via a screw (33) so as to be able to adjust the pump stroke length / position of the piston (1), and which system also comprises a central computer for controlling the valves ( 3.27) and the controllable motor (37). System according to claim 1, characterized in that the nozzle comprises a cylindrical nozzle rod (2) for mounting through a hole (4) in the cylinder wall, the nozzle rod having a central passage (14) for a needle valve body (18) spring-loaded in outward direction for closing an inner valve seat in a nozzle mouth of the nozzle rod, and a second passage (24) for controlled application of pressure oil to a front pressure chamber (30) wherein the pressure oil can exert both a backpressure of the needle valve body for opening the inner valve seat and an overpressure injection of oil through the nozzle thus opened until the oil pressure is lowered for effective closure of the needle valve, said second passage being a channel (24) between an outer tube cylindrical nozzle (2) and a centrally located feed tube (22) therein of the needle valve body (18). System according to claim 1 or 2, characterized in that the piston (1) is loaded by a spring (Γ) which presses the piston against an oil supply space (5) when the system is pressure-free. System according to claim 1, 2 or 3, characterized in that in the nozzle (11) there is an outer inclined nozzle channel (12). System according to any one of the preceding claims, characterized in that the injection nozzle and the controllable motor are arranged concentrically about a common axis. System according to any one of claims 2-5, characterized in that the spring (32) acting on the needle valve body is in contact with a longitudinally slidable slide (34), the stroke length / position of which is determined by the controllable motor (37). ). System according to claim 6, characterized in that the slide (34) is rotationally held by a guide (35). System according to any one of claims 2-7, characterized in that the spring (32) acting on the needle valve body has a bias corresponding to the desired closing pressure for the valve needle (18).
