SIVULUUKKUJÄRJESTELY - ARRANGEMANG FÖR SIDOLUCKASIDE DOOR ARRANGEMENT - ARRANGEMANG FÖR SIDOLUCKA

Keksinnön kohteena on patenttivaatimuksen 1 johdanto-osan mukainen sivuluukkujärjestely, joka voidaan asentaa esimerkiksi polttomoottorin, erityisesti ison dieselmoottorin ohjaussivulle.The invention relates to a side hatch arrangement according to the preamble of claim 1, which can be mounted, for example, on the control side of an internal combustion engine, in particular a large diesel engine.

5 Isoilla dieselmoottoreilla tarkoitetaan tässä mm. sellaisia moottoreita, jotka soveltuvat esimerkiksi laivojen apu- tai pääkoneiksi ja lämmitysvoimalaitoksiin. Tällaisissa moottoreissa on tavanomaista järjestää toiselle pituussuuntaiselle sivulle esimerkiksi imu- ja pakosarjat sekä 10 moottorin jäähdytysnesteen siirtojärjestelmät. Vastaavasti toiselle ns. ohjaussivulle voidaan erityiselle sivuluukuilla suojatulle pumppuhyllylle järjestää esimerkiksi polttoaineen syöttölaitteet ja siirtojärjestelmät sekä venttiilien ohjausjärjestelmät. Koska pumppuhyllylle siten pitää johtaa 15 eri tarkoituksia varten kaasua, nestettä ja/tai kiinteätä ainetta, pumppuhylly joudutaan ahtamaan täyteen putkia. Tämän seurauksena pumppuhylly on yleensä kovin ahdas, koska toisaalta pyritään siihen, ettei moottori leveyssuunnassa kasva liikaa ja siten mahdollisesti sulje pois joitakin 20 käyttökohteita. Siten tunnetuissa ratkaisuissa pumppuhyllyn tilan ahtaus vaikeuttaa olennaisesti asennus-ja purkamistoi-menpiteitä ja moottorin huoltamista.5 Large diesel engines here mean e.g. engines suitable, for example, for auxiliary or main engines of ships and for heating power plants. In such engines, it is customary to arrange on the other longitudinal side, for example, intake and exhaust manifolds and 10 engine coolant transfer systems. Correspondingly, to another so-called. on the control side, for example, fuel supply devices and transfer systems as well as valve control systems can be arranged on a special pump shelf protected by side hatches. Thus, since gas, liquid and / or solids must be supplied to the pump shelf for 15 different purposes, the pump shelf has to be filled with pipes. As a result, the pump shelf is usually very narrow, as on the other hand the aim is not to grow too much in the width direction of the motor and thus possibly exclude some 20 applications. Thus, in known solutions, the congestion of the pump shelf substantially complicates installation and disassembly procedures and motor maintenance.

Keksinnön tarkoituksena on helpottaa pumppuhyllyllä vallitsevaa tilanahtautta. Erityisesti tarkoituksena on 25 aikaansaada rakenteeltaan ja kokoonpanonsa kannalta edullinen ratkaisu, jonka ansiosta huomattava osa tavanomaisen tekniikan mukaisesti pumppuhyllylle eri väliaineiden siirtämistä varten asennettavista erillisistä putkista voidaan eliminoida.The object of the invention is to alleviate the congestion prevailing on the pump shelf. In particular, it is intended to provide a solution which is advantageous in terms of structure and configuration, by means of which a considerable part of the separate pipes to be mounted on the pump shelf for conveying various media according to the conventional technology can be eliminated.

30 Keksinnön tavoitteet saavutetaan patenttivaatimuksessa 1 ja alivaatimuksissa tarkemmin esitetyllä tavalla. Keksinnön 2 7751 3 mukaisesti siis pumppuhyllyä suojaava sivuluukkuelementti järjestetään toimimaan samalla väliaineita johtavana putkena varustamalla se kanavilla, joita pitkin ainakin pääosa pumppuhyllylle tai -hyllyltä siirrettävistä väliaineista 5 voidaan johtaa. Käytännössä näitä kanavia voidaan edullisesti käyttää esimerkiksi moottorin sylintereiden käynnistysvent-tiileiden pneumaattisen ohjauksen järjestämiseksi. Samoin voidaan esimerkiksi moottorin polttoaineenruiskutuspumpuista johtaa pois ylimääräinen polttoaine tällaista sivuluukkuele-10 menttiin järjestettyä kanavaa pitkin syötettäväksi sitten uudelleen pumppuihin.The objects of the invention are achieved as specified in claim 1 and the subclaims. Thus, according to the invention 2 7751 3, the side hatch element protecting the pump shelf is arranged to act at the same time as a medium-conducting pipe by providing it with channels through which at least most of the media 5 to be transferred to or from the pump shelf can be led. In practice, these channels can advantageously be used, for example, to provide pneumatic control of the starting valves of the engine cylinders. Likewise, for example, excess fuel can be drained from the engine's fuel injection pumps via such a channel arranged in the side hatch element 10 for re-supply to the pumps.

Keksinnön mukainen sivuluukkuelementti voidaan edullisesti valmistaa alumiiniprofiilista, jolloin elementtiin valmistuksen yhteydessä voidaan samalla järjestää pituussuuntainen 15 ura tiivistettä varten elementin tiivistämiseksi moottorin runkoon. Näin keksinnön mukainen sivuluukkuelementti kanavineen, syöttö- ja poistoaukkoineen liitäntäelimille sekä tiivisteineen voidaan liittää integroiduksi kokonaisuudeksi moottorin pumppuhyllyyn ja sitä hyväksikäyttäviin 20 järjestelmiin.The side hatch element according to the invention can advantageously be made of an aluminum profile, whereby a longitudinal groove 15 for a seal can be provided in the element during manufacture in order to seal the element to the motor body. Thus, the side hatch element according to the invention with its ducts, inlet and outlet openings for the connecting members and with its seals can be connected as an integrated unit to the motor pump shelf and the systems utilizing it.

Keksintöä selostetaan seuraavassa viitaten oheiseen piirustukseen, jossa kuvio 1 esittää yleiskuvana erään moottorin pumppuhyllyn käsittävän moottorilohkon osaa leikattuna, 25 - kuvio 2 esittää keksinnön mukaista moottorin pumppuhyl lyn sivuluukkujärjestelyä moottorirunkoon kiinnitettynä ja päädystä katsottuna.The invention will now be described with reference to the accompanying drawing, in which Figure 1 shows an overview of a part of a motor block comprising an engine pump shelf in section, Figure 2 shows a side view of a motor pump shelf according to the invention attached to the motor body and seen from the end.

Piirustuksessa tarkoittaa viitenumero 1 moottorin pumppuhyllyä. Viitenumero 2 tarkoittaa yleisesti pumppuhyllyn 30 suojakoteloa, joka voi muodostua useammasta toisiinsa liitetystä kotelonosasta. Numero 2a viittaa erääseen keksinnön mukaisen sivuluukkuelementin sovellutusmuotoon.In the drawing, reference numeral 1 denotes a motor pump shelf. Reference numeral 2 generally denotes a protective housing for the pump shelf 30, which may consist of a plurality of interconnected housing parts. The number 2a refers to an embodiment of a side hatch element according to the invention.

Viitaten kuvioon 2 sivuluukkuelementti 2a on tuettu moottorin runkoon 3 pulteilla 10 ja tiivistetty uraan 9 asennetullaReferring to Fig. 2, the side hatch element 2a is supported on the motor body 3 by bolts 10 and sealed with a groove 9 mounted

Claims

3 77513 with a seal 11. The side hatch element 2a is further supported at both ends by the use of bores 7 in the motor frame or in an element supported thereon (not shown in the figures). As can be seen from Fig. 1, the side hatch element 2a according to Fig. 2 forms the lower part of the protective housing of the pump shelf. The side hatch element 2a is provided with longitudinal channels 4 of the element and associated supply openings 8, through which control air can be supplied to the pneumatically controlled starting valves of the engine cylinders 10 by connecting suitable pipes or hoses to the supply openings. The side hatch element 2a is also provided with a duct 5, which is connected via connecting pipes 6 to the fuel injection pumps in order to drain the excess fuel out 15 for possible refueling. It is clear that the side hatch element according to the invention can in practice be shaped in several different ways and provided with different amounts of channels of different sizes and shapes with their connecting members as required. The invention can also be applied to other applications where hatches and medium transfer are required. The invention is thus not limited to the embodiment shown, but several variations are conceivable within the scope of the appended claims.
