Description

本発明は、少なくとも１つの高圧貯蔵器を備え、その高圧貯蔵器から加熱された燃料が弁を介して内燃機関の各シリンダに導入され、高圧貯蔵器が、圧力状態にある燃料を収容する内部の圧力容器と、圧力容器を取囲み圧力容器との間に中空空間を形成する外被とを有している、重油で駆動される内燃機関の燃料供給装置に関する。   The present invention includes at least one high-pressure reservoir, and fuel heated from the high-pressure reservoir is introduced into each cylinder of the internal combustion engine via a valve, and the high-pressure reservoir contains fuel in pressure state. And a fuel supply device for an internal combustion engine driven by heavy oil, having a pressure vessel surrounding the pressure vessel and forming a hollow space between the pressure vessel and the pressure vessel.

この種の燃料供給装置は特許文献１に記載されている。
欧州特許出願公開第１３１４８８３号明細書 This type of fuel supply apparatus is described in Patent Document 1.
European Patent Application No. 1314883

本発明の課題は圧力容器内に存在する燃料の熱損失を低減することである。   The object of the present invention is to reduce the heat loss of the fuel present in the pressure vessel.

この課題は、本発明により、中空空間の少なくとも一部が、少なくとも噴射すべき燃料の温度にほぼ一致する温度を有する流体を与えられることによって達成される。この発明によれば、圧力容器の壁を通して外部へ向かう熱伝導を回避することができる。燃料の温度を超える温度を有する流体を用いることによって、その流動性を向上させることができる。なお、外被内には流体の流入管および流出管が連通しているとよい。   This object is achieved according to the invention in that at least a part of the hollow space is provided with a fluid having a temperature which at least approximately corresponds to the temperature of the fuel to be injected. According to the present invention, heat conduction toward the outside through the wall of the pressure vessel can be avoided. By using a fluid having a temperature exceeding the temperature of the fuel, its fluidity can be improved. Note that an inflow pipe and an outflow pipe for fluid are preferably communicated with each other in the outer casing.

本発明の１つの実施態様によれば、圧力容器の両側がそれぞれパッキングを介在させて蓋によって閉鎖され、中空空間の内部に、各パッキングから僅かな間隔をおいて別のパッキングが配置され、その別のパッキングが、排出口を備えた漏れ燃料だめを、流体を与えられる中空空間の残余の部分から分離する。   According to one embodiment of the present invention, both sides of the pressure vessel are respectively closed by a lid with a packing interposed therebetween, and another packing is arranged inside the hollow space at a slight distance from each packing, Another packing separates the leaking fuel sump with the outlet from the remainder of the hollow space to which fluid is provided.

好ましくは、流体は僅かな圧力状態にある加熱された燃料である。これは何れにしても使えるので、本発明の実現のためには簡単な導管しか必要とされない。   Preferably, the fluid is a heated fuel at a slight pressure. Since this can be used anyway, only a simple conduit is required to implement the present invention.

本発明の他の実施態様によれば、流体、例えば油または蒸気のための特別な循環路が設けられる。その場合、圧力容器内に存在する燃料の付加的な加熱の可能性がある。   According to another embodiment of the invention, a special circuit for a fluid, for example oil or steam, is provided. In that case, there is the possibility of additional heating of the fuel present in the pressure vessel.

本発明の別の実施態様によれば、圧力容器および外被が円筒状に形成され、各パッキングがＯリングとして構成されている。Ｏリングは耐熱性かつ耐燃料性のエラストマからなるとよい。   According to another embodiment of the present invention, the pressure vessel and the jacket are formed in a cylindrical shape, and each packing is configured as an O-ring. The O-ring is preferably made of a heat resistant and fuel resistant elastomer.

以下において本発明を図面を参照して詳細に説明する。
図１は高圧貯蔵器を概略的に示し、
図２は高圧貯蔵器の端部領域を示す。 Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 schematically shows a high pressure reservoir,
FIG. 2 shows the end region of the high pressure reservoir.

図面には高圧貯蔵器の円筒状に形成された圧力容器が符号１で示されている。圧力容器１は同様に円筒状に形成された外被４によって取囲まれ、圧力容器１と外被４との間に中空空間５が形成されている。圧力容器１の両側は各蓋２，３によって閉鎖されている。蓋２，３には高圧状態にある加熱された燃料の導入路および導出路が形成されている。   In the drawing, a pressure vessel formed in a cylindrical shape of a high-pressure reservoir is denoted by reference numeral 1. Similarly, the pressure vessel 1 is surrounded by a jacket 4 formed in a cylindrical shape, and a hollow space 5 is formed between the pressure vessel 1 and the jacket 4. Both sides of the pressure vessel 1 are closed by respective lids 2 and 3. The lids 2 and 3 are formed with inlets and outlets for heated fuel in a high pressure state.

中空空間５は、図２に詳細に示されているように、Ｏリングとして形成されたパッキング７によって封止されている。図示の実施例においては、中空空間５の内部に同様にＯリングとして形成された別のパッキング８が設けられている。これらのＯリングは耐熱性かつ耐燃料性のエラストマで作られている。パッキング７，８は漏れ燃料だめ９を画成する。従って、漏れ燃料だめ９は外部に対しても中空空間５の残余の部分に対しても閉鎖される。漏れ燃料だめ９内には排出口１０が連通している。圧力容器１の他方の端部にも同一の構造部が設けられる。   The hollow space 5 is sealed by a packing 7 formed as an O-ring, as shown in detail in FIG. In the illustrated embodiment, another packing 8 that is also formed as an O-ring is provided inside the hollow space 5. These O-rings are made of a heat and fuel resistant elastomer. Packings 7 and 8 define a leaking fuel sump 9. Accordingly, the leaking fuel sump 9 is closed both to the outside and to the remaining part of the hollow space 5. A discharge port 10 communicates with the leaked fuel sump 9. The same structural portion is also provided at the other end of the pressure vessel 1.

中空空間５内には流体の流入口１１および流出口１２が連通している。この流体の温度は噴射すべき燃料の温度にほぼ一致する。この流体は最も簡単には低圧状態にある加熱された燃料である。その場合、圧力容器１内に含まれ高圧状態にある加熱された燃料の冷却が大幅に回避される。   In the hollow space 5, a fluid inlet 11 and an outlet 12 communicate. The temperature of this fluid approximately matches the temperature of the fuel to be injected. This fluid is most simply heated fuel at low pressure. In that case, cooling of the heated fuel contained in the pressure vessel 1 and in a high pressure state is greatly avoided.

しかし、中空空間５には、噴射すべき燃料の温度より高い温度の流体を与えることもできる。この流体は油または蒸気であってよく、この流体のために別個の循環路が設けられねばならない。   However, a fluid having a temperature higher than the temperature of the fuel to be injected can be given to the hollow space 5. This fluid can be oil or steam and a separate circuit must be provided for this fluid.

燃料漏れを監視する必要がなければ、パッキング８は省略することができる。   If there is no need to monitor for fuel leaks, the packing 8 can be omitted.

本発明は図示された実施例に限定されず、例えば圧力容器をより長く構成すれば、内燃機関の全てのシリンダに燃料を供給するために１つの圧力容器のみが必要されるだけとなる。   The invention is not limited to the embodiment shown, but for example if the pressure vessel is made longer, only one pressure vessel is needed to supply fuel to all cylinders of the internal combustion engine.
