****- #l |t r- , Int. CL* F02D 1/10 Twórca wynalazku: Uprawniony z patentu: Friedmann & Maier Aktiengesellschaft, Hallein (Austria) Urzadzenie regulacyjne dla pomp wtryskowych Przedmiotem wynalazku jest urzadzenie regula¬ cyjne dla pomp wtryskowych silników pracuja¬ cych z wtryskiem paliwa i wyposazonych w spre¬ zarki doladowujace, w których wahliwy wspornik zderzaka polaczonego z drazkiem regulacyjnym jest przestawiamy przez przepone obciazona cis¬ nieniem wytwarzanym przez sprezarke dolado¬ wujaca, w celu ograniczenia ruchu drazka regula¬ cyjnego, przy czym obudowa przepony jest przy¬ krecona swym kolnierzem do obudowy regulatora.**** - #l | t r-, Int. CL * F02D 1/10 Inventor: The holder of the patent: Friedmann & Maier Aktiengesellschaft, Hallein (Austria) Regulating device for injection pumps The subject of the invention is a regulating device the injection pumps for the engine injection pumps are working fuel-injected and compressed-air charging cranes, in which a pivoting bracket a bumper with an adjustment stick is set through the pressure-loaded diaphragm by the addition of the compressor uujaca, in order to limit the movement of the stick adjustable the diaphragm housing is screwed with its flange to the regulator housing.
Obudowa przepony powieksza wymiary obudo¬ wy regulatora. Pompy wtryskowe sa wraz z re¬ gulatorami dobudowywane do silników spalino¬ wych i powiekszenie wymiarów obudowy regula¬ tora stwarza trudnosci, poniewaz w wiekszosci przypadków przestrzen stojaca do dyspozycji dla dobudowania pompy wtryskowej z regulatorem jest ograniczona.The diaphragm housing increases the dimensions of the housing you of the regulator. The injection pumps are together with re¬ gulators attached to the engines and increasing the dimensions of the regulating casing the tora poses difficulties because for the most part cases available space for add-on injection pump with regulator is limited.
Celem wynalazku jest usuniecie powyzszych niedogodnosci.It is an object of the invention to overcome the above inconvenience.
Cel ten wedlug wynalazku osiagnieto przez to, ze obudowa regulatora ma co najmniej dwa, za¬ krywane kolnierzami, wyciecia z gniazdami kol¬ nierzowymi dla obudowy przepony, których osie leza w tej samej plaszczyznie prostopadlej wzgle¬ dem osi obrotu zderzaka i korzystnie w takim marnym odstepie od tej osi obrotu i od umieszczo¬ nych pod katem wzgledem siebie scian obudowy regulatora. U/stawienie wyciec z gniazdami dla kolnierzy w tej samej plaszczyznie prostopadlej wzgledem osi obrotu zderzaka umozliwia latwe polaczenie czlonu ' wykonawczego przepony ze wspornikiem wahiliwego zderzaka, poniewaz we wszystkich polozeniach kolnierza obudowy prze¬ pony, czlon wykonawczy przepony moze dzialac w tym samym obszarze wahliwego wspornika zde¬ rzaka co pozwala na przykrecenie obudowy prze¬ pony do obudowy regulatora w dowolnych, z góry okreslonych miejscach. W ten sposób mozna do¬ stosowac sie do istniejacych warunków zabudo¬ wy. W silnikach widlastych wysokosc zabudowy przewidziana dla pompy wtryskowej z regulato¬ rem jest ograniczona i dlatego jest celowym by obudowe przepony umieszczac poziomo. W silni¬ kach rzedowych dopuszczalna jest znacznie wiek¬ sza wysokosc zabudowy i dlatego w tych przy¬ padkach mozna korzystnie obudowe przepony umieszczac pionowo. Jak widac mozna dolaczac pompe wtryskowa wraz z regulatorem do silnika spalinowego nie zwiekszajac nadmiernie zapotrze¬ bowania na zajmowana przestrzen. Jezeli osie gniazd kolnierzy sa umieszczone w tej samej pla¬ szczyznie prostopadlej wzgledem osi obrotu zde¬ rzaka i gniazda sa umieszczone w jednakowej od¬ leglosci od tej osi, wówczas czlon wykonawczy przepony moze pozostac niezmieniony. Jezeli jed¬ nak ze wzgledów konstrukcyjnych, odstepy te mu¬ sza byc rózne, to wówczas czlon wykonawczy przepony moze byc dostosowany do róznych od¬ stepów. 105 537^C i fr' Korzystne jest, gdy wahliwy wspornik zderzaka ma dwa czopy przestawione wzgledem siebie o kat odpowiadajacy katowi który tworza miedzy soba prostopadle do gniazd ^^p^^^^.}^Tj^_^^ji; wykonawczy przepony ma co najmniej jedno wy¬ branie obejmujace jeden z czopów. Dzieki temu, ze na wahliwym wsporniku zderzaka sa przewi¬ dziane dwa czopy przesuniete wzgledem siebie o kat odpowiadajacy katowi miedzy prostopadly¬ mi do kolnierzy, to we wszystkich polozeniach kolnierzy, takim samym ruchom przepony odpo¬ wiadaja - takie same przekrecenia wspornika zde-* rzaka i dzieki czemu, bez przestawiania ukladu przepony utrzymuje sie; takie same warunki regu¬ lacji przy wszystkich ustawieniach kolnierzy obu-* dowy przepony. Jezeli jeszcze jest spelnione wy¬ maganie ze poszczególne gniazda¦-„fcolnje.rzy sa umieszczone w takim samym odstepie od osi obro¬ tu wspornika zderzaka, Ho wówczas wystarcza jed- nff ^wytoranir na "cztonte^wyteonawczym przeponyr Jezeli odstepy nie sa jednakowe wówczas moze to byc skorygowane tym, ze czlon wykonawczy przepony posiada drugie wybranie, które jest przesuniete wzgledem pierwszego wybrania o róz¬ nice odstepów.This aim, according to the invention, is achieved by that the regulator housing has at least two terminals with collars, cut-outs with collets for the diaphragm casing, the axes of which they lie in the same plane, perpendicular to it and preferably therein a poor distance from this axis of rotation and from its position walls of the housing at an angle to each other regulator. Set up a leak with sockets for flanges in the same plane perpendicular in relation to the axis of rotation of the bumper makes it easy connection of the actuator member of the diaphragm with the support for the swinging bumper, because we all positions of the housing flange pony, the executive member of the diaphragm can operate in the same area of the pivoting support deflection rape which allows for screwing on the housing pony to the regulator housing at any, in advance specific places. This way you can do adhere to the existing building conditions you. For V-engines, the build-in height provided for a regulated injection pump rem is limited and therefore it is advisable to place the diaphragm casing horizontally. In the engine significantly age is allowed higher building height and therefore in these cases in cases, preferably the diaphragm housing placed vertically. As you can see you can join injection pump with engine regulator without increasing the demand excessively bouncing on the occupied space. If the axes the sockets of the flanges are placed on the same plane vertically perpendicular to the axis of rotation the rapeseed and nests are located in the same shape legality from this axis, then the executive member the diaphragm can remain unchanged. If you eat for construction reasons, these gaps must be if you want to be different, it is then the executive member the diaphragm can be adjusted to different variations steppes. 105 537 ^ C and fr ' It is advantageous when a pendulum bumper support has two pivots staggered to each other by cat corresponding to the angle that they create between themselves perpendicular to the nests ^^ p ^^^^.} ^ Tj ^ _ ^^ ji; the actuator of the diaphragm has at least one output a bite involving one of the pins. Thanks ago, that they are scrolled on the swivel bracket of the bumper knitted two studs shifted relative to each other with the angle corresponding to the angle between the perpendicular to the collars, in all positions flanges, the same movements of the diaphragm respond they say - the same swings of the bracket de- * rake and therefore, without rearranging the system the diaphragm persists; same conditions lation with all collar settings - * diaphragm. If it is still satisfied, maganie from individual sockets¦- “fcolnje.rzy sa placed at the same distance from the axis of rotation here, the bumper bracket, Ho then one nff ^ wytoranir on the "fouronstructive" diaphragm If the intervals are not equal then maybe this be corrected by the fact that the executive member the diaphragm has a second recess which is moved relative to the first recess by a rose nice gaps.
Wedlug wynalazku, czlon wykonawczy przepony moze byc polaczony z wahliwym wspornikiem zderzaka przez zazebienia palcowe; w innym roz¬ wiazaniu, wahliwy wspornik zderzaka moze byc wyposazony w kolo zebate podczas g4y czlon wy¬ konawczy przepony stanowi zebatke.According to the invention, the actuator of the diaphragm can be combined with a swinging bracket the bumper by the finger gears; in another chapter a binding, a pendulous bumper bracket can be equipped with a gear wheel during the top switch the end of the diaphragm is a tooth.

Przesuniecie drazka regu¬ lacyjnego w lewo powoduje zwiekszenie ilosci pa¬ liwa wtryskiwanego do cylindrów silnika. Na gór¬ nem koncu dzwigni posredniej 1 jest zamocowana obrotowo rolka 4. Zderzak 5, który znajduje sie na torze ruchu rolki 4 spelniajacej role przeciwzde- rzaka ogranicza ruch drazka regulacyjnego 2 w kierunku odpowiadajacym wiekszym ilosciom wtryskiwanego paliwa. Zderzak 5 ma ksztalt krzywki i jest zamocowany na waMiwym wspor¬ niku 6, który jak to pokazano na fig. 3 i 4, moze bye przekrecany przez czlon wykonawczy przepo¬ ny 14 anajdugacej sie pod dzialaniem cisnienia do¬ ladowujacego. Przykrecona kolnierzem do pompy wtryskowej 17 dwuczesciowa obudowa regulatora 1S, 16, ma dwa wyciecia 18, 19. W wyciecie 1* wnika czlon wykonawczy 7 przepony 14, nato- nwhbst wyciecie 49 jest zamkniete kolnierzem 26.The subject matter of the invention is illustrated in example the embodiment in the drawing in which fig. 1 shows a partial longitudinal section along the line fr-rl marked in Fig. 2 by the housing re ~ lulator with a bolted diaphragm casing, Fig. 2 - a partial section through the controller housing along the line II-II marked in fig. 1, fig. 3 - a section taken along the line III— «IH marked in Figure 2, and Figs. 4-8 another device variant * in section w / sd & iznym. \ l> Intermediate lever 1 via link the articulated link 3 transmits depending on the rotation these movements of the not shown regulatory shunt on the regulating stick 2. Move the regulating stick to the left increases the amount of steam fuel injected into the engine cylinders. Upstairs the end of the intermediate lever 1 is attached rotating roller 4. Bumper 5, which is located at the motion track of the roller 4 fulfilling the role of rape restricts the movement of the regulating rod 2 in the direction of larger quantities injected fuel. The bumper 5 is shaped cam and is fixed on a valid support 6, which as shown in Figs. 3 and 4, may I was twisted by the flow executive ny 14 anindrugated under pressure to¬ the landing gear. Screwed with a flange to the pump Injection 17 two-piece regulator housing 1S, 16, has two cuts 18, 19. In cut 1 * the actuator 7 of the diaphragm 14 penetrates, while nwhbst cut 49 is closed with a collar 26.
Przy wycieciach 16, W przewidziano gniazda 21, 22 dla kolnierzy obudowy przepony 23. Czlon wy- ¦j 'k v.With 16, W cutouts, 21 slots are provided, 22 for diaphragm housing flanges 23. The ¦j 'k v.
