(57) [Summary] [Purpose] The oil filter container has a double wall structure
The space between the heavy walls is filled with a heat storage agent that forms a liquid phase at room temperature, and the oil pressure of the low temperature oil presses the nuclear generator to solidify and generate heat, and the temperature of the oil is quickly raised to the proper viscosity. A body 2 of an oil filter 1 is a double wall having an outer wall 10 and an inner wall 11, and a heat storage agent 15 in a liquid phase is enclosed in a space between them. With the start of the internal combustion engine, low-temperature and high-viscosity oil is pressure-fed into the container and presses the nuclear generator arranged in the heat storage agent via the pressure receiving window 13 provided on the inner wall 11.
Since the exothermic agent solidifies and generates heat by the operation of the nuclear generator, the oil is quickly warmed to an appropriate viscosity. When the temperature of the oil rises above a certain value, the heat storage agent liquefies and maintains the liquid phase even at room temperature.
Description
【0001】[0001]
この考案は内燃機関用のオイルフィルタに関する。 This invention relates to an oil filter for an internal combustion engine.
【0002】[0002]
内燃機関の摺動部に供給されるオイルは適度の粘度範囲に維持される必要があ るが、特に寒冷期の機関始動に際しては、オイルが低温で粘度が高いため送油管 路の抵抗が高くなって摺動部への供給量が不足し、エンジン焼けを発生させるお それがあり、あるいは摺動部の摩擦抵抗が大になって燃費が増大するという問題 がある。 The oil supplied to the sliding parts of an internal combustion engine must be maintained in an appropriate viscosity range, but especially when the engine is started in the cold season, the oil has a low temperature and a high viscosity, so the resistance of the oil supply line is high. Then, there is a problem that the supply amount to the sliding part becomes insufficient and engine burnt occurs, or the frictional resistance of the sliding part becomes large and the fuel consumption increases.
【0003】 その対策として例えば特開昭55ー54619号公報に開示されたオイルフィ ルタは、容器を2重壁とし、2重壁の間に冷却水を流通させるようにしている。 これはオイルよりも冷却水の方が始動時の温度上昇が速いので、機関運転開始初 期には冷却水からオイルに熱を与えてオイルの昇温を速め粘度を低下させようと するものである。As a countermeasure, for example, an oil filter disclosed in Japanese Patent Laid-Open No. 55-54619 has a double wall container and cooling water is circulated between the double walls. This is because the temperature of cooling water rises faster than that of oil at the time of starting, so at the beginning of engine operation, heat is applied to the oil from the cooling water to accelerate the temperature rise of the oil and reduce the viscosity. is there.
【0004】 また、実開昭59ー152171号公報には容器に電熱ヒータを埋設したディー ゼルエンジンの燃料フィルタが記載されている。これは低温時に特に低質燃料 の柝出物によりフィルタが目詰まりを起こすのを防ぐ目的で燃料を加温するもの である。Further, Japanese Utility Model Laid-Open No. 59-152171 discloses a fuel filter for a diesel engine in which an electric heater is embedded in a container. This is to heat the fuel at a low temperature in order to prevent the filter from being clogged with the exudates of low quality fuel.
【0005】[0005]
上記のような従来のものはいずれも容器に加熱手段を設けて、容器内へ流入す るオイル又は燃料を昇温させるものであるが、前者のオイルフィルタは容器の2 重壁間の空間を冷却水系の配管に接続するものであるから、配管のスペースを必 要とし、水洩れ防止等の保守管理を必要とする。また冷却水の昇温は必ずしも十 分に速いとはいえないから、オイルの受熱昇温も遅い。 In all of the above conventional devices, a heating means is provided in the container to raise the temperature of the oil or fuel flowing into the container. However, the former oil filter uses a space between the double walls of the container. Since it is connected to the cooling water piping, it requires space for piping and maintenance management such as water leakage prevention. In addition, the temperature rise of the cooling water is not necessarily fast enough, so the temperature rise of the heat received by the oil is slow.
【0006】 後者の燃料フィルタの構造をオイルフィルタに転用することも考えられるが、 電熱ヒータはスイッチを介在させて電源と接続しなければならない。このスイッ チが手動のものであればスイッチ投入忘れによる不作動や開放忘れによる過熱の おそれがあり、自動制御をするには機関始動との連動投入手段、タイマーや油温 センサ等を用いた開放手段等、検知手段を含む制御回路を設けなければならない 。The latter fuel filter structure may be used for an oil filter, but the electric heater must be connected to a power source with a switch interposed. If this switch is a manual switch, there is a risk of inoperability due to forgetting to turn on the switch or overheating due to forgetting to open the switch.In order to perform automatic control, the opening means linked with the engine start, the timer and the oil temperature sensor are used. A control circuit including detection means such as means must be provided.
【0007】 いずれの場合もオイルフィルタに外部からの配管や配線を接続して熱源エネル ギを送入し、制御しなければならない。In either case, the heat source energy must be fed and controlled by connecting an external pipe or wiring to the oil filter.
【0008】[0008]
この考案のオイルフィルタは容器を2重壁とし、2重壁間の空間に常温で液相 をなす蓄熱材を封入し、2重壁のうちの内側壁に受圧窓を設け、前記空間内に受 圧窓に臨ませて発核器を配設し、容器内へ流入するオイルの圧力を受圧窓を介し て発核器に検知させ、発核器の作動により蓄熱剤を固相とし発熱させるものであ る。 The oil filter of the present invention has a container having a double wall, a space between the double walls is filled with a heat storage material which is in a liquid phase at room temperature, and a pressure receiving window is provided on an inner side wall of the double wall. A nuclear generator is placed facing the pressure receiving window, and the pressure of the oil flowing into the container is detected by the nuclear generator through the pressure receiving window, and the heat storage agent turns into a solid phase to generate heat by the operation of the nuclear generator. It is a thing.
【0009】[0009]
内燃機関の始動に伴い無圧状態のオイルフィルタ容器に、圧送されたオイルの 初期圧力が作用する。この初期圧力を受圧窓を介して発核器が検知し作動すると 、蓄熱剤が固相となり発熱する。この熱は容器の内側壁を介してオイルに与えら れオイルは速かに昇温し粘度を下げる。蓄熱剤の固化が完了すると発熱も停止す る。 When the internal combustion engine is started, the initial pressure of the oil that has been pumped acts on the oil filter container that is in a non-pressure state. When the nuclear generator detects this initial pressure through the pressure receiving window and operates, the heat storage agent becomes a solid phase and generates heat. This heat is given to the oil through the inner wall of the container, and the temperature of the oil rises rapidly and the viscosity decreases. When the solidification of the heat storage agent is completed, heat generation also stops.
【0010】 蓄熱剤は更に高温に加熱されると液相になり、温度が常温に至っても液相を維 持するから、このオイルフィルタ内のオイルが機関の運転継続で更に昇温しオイ ルクーラ等の作用で適正範囲の高温に維持されると、蓄熱剤はオイルから熱を受 けて液相となり、運転停止後常温まで温度が低下しても液相を保つ。The heat storage agent becomes a liquid phase when heated to a higher temperature and maintains the liquid phase even when the temperature reaches room temperature. Therefore, the oil in the oil filter further rises in temperature while the engine continues to operate and the oil cooler When maintained at a high temperature within the proper range due to such actions, the heat storage agent receives heat from the oil and becomes a liquid phase, which remains in the liquid phase even if the temperature drops to normal temperature after the operation is stopped.

図1に実施例を示す。オイルフィルタ1はカップ状のボディ2の開口端を、オ イルの入口孔4、出口孔5を有するカバー3で被って容器とし内部にフィルタエ レメント6を配設しセンターボルト7でボディ2、カバー3を締付けるとともに 、スプリング8を介在させてフィルタエレメントをカバー3側へ押圧して成る。 An example is shown in FIG. The oil filter 1 is a container in which the open end of a cup-shaped body 2 is covered with a cover 3 having an oil inlet hole 4 and an oil outlet hole 5, and a filter element 6 is disposed inside the body. 3 is tightened and the filter element is pressed toward the cover 3 side with the spring 8 interposed.
【0012】 ボディ2はセンターボルト7を挿通させる開口9の周囲を除き、外側壁10、 内側壁11で構成する2重壁となっており、それらの間に間隙12を形成してい る。また内側壁11には複数の受圧窓13を設ける。受圧窓13は、小面積の開 口を合成樹脂でなる弾性膜14で液密に被い周縁にシール剤を塗布して窓枠リン グ17を溶接固着する。間隙12内に常温で液相をなす蓄熱剤15を封入し、受 圧窓13に臨ませて発核器16を配設する。The body 2 is a double wall composed of an outer wall 10 and an inner wall 11 except for the periphery of an opening 9 through which the center bolt 7 is inserted, and a gap 12 is formed between them. Further, a plurality of pressure receiving windows 13 are provided on the inner wall 11. The pressure receiving window 13 covers the opening of a small area with an elastic film 14 made of synthetic resin in a liquid-tight manner and applies a sealant to the peripheral edge to weld and fix the window frame ring 17. A heat storage agent 15, which is in a liquid phase at room temperature, is enclosed in the gap 12, and the nuclear generator 16 is arranged so as to face the pressure receiving window 13.
【0013】 蓄熱材15は例えば特開昭60ー120785公報、あるいは特開昭60ー1 68983号公報に開示されたような酢酸ナトリウム系のもので、固化を誘発す る結晶核形成剤を含有させたものである。発核器は小型の押釦様のもので蓄熱剤 の中に適宜数配設され、外部からの圧力により蓄熱剤に機械的刺激を与え発熱剤 の固化を発進させるものである。蓄熱剤は80゜〜90゜まで加熱されると液化 し、温度が常温まで降下しても液相を保つ。The heat storage material 15 is, for example, a sodium acetate-based material as disclosed in JP-A-60-120785 or JP-A-60-168983, and contains a crystal nucleating agent that induces solidification. It was made. Nucleators are like small pushbuttons, and are arranged in an appropriate number in the heat storage agent, and mechanically stimulate the heat storage agent by external pressure to start solidification of the heat generating agent. The heat storage agent liquefies when heated to 80 ° to 90 ° and maintains the liquid phase even when the temperature drops to room temperature.
【0014】 図2に示すようにボディ2の2重壁構造は、中央にボルト孔20を有する外側 壁10とボルト孔21を有する内側壁11とを、ボルト孔部分に環状スペーサ2 2を挟んで一体ろう付けしたものである。下方の開口端の2重壁の間の隙間から 蓄熱剤15を封入し、発核器16を受圧窓13の位置に合わせて配置し、前記隙 間に環状の封止リング23を嵌め込んでシール剤を施し、外側壁10、封止リン グ23、内側壁11の下端縁を囲んでかしめリング24でかしめる。尚蓄熱縁剤 15を封入する際気泡を存在させて液固相変態の際の容積変化に対応させる。ボ ディ2はこのようにして形成する。またこの考案は使い捨て型オイルフィルタに も適用できる。その場合はボディ2の開口9、すなわち図2のボルト孔20、2 1を設けてないものとする。As shown in FIG. 2, the double-wall structure of the body 2 has an outer wall 10 having a bolt hole 20 in the center, an inner wall 11 having a bolt hole 21, and an annular spacer 22 sandwiched in the bolt hole portion. It was brazed together. The heat storage agent 15 is sealed from the gap between the double walls at the lower opening end, the nuclear generator 16 is arranged in accordance with the position of the pressure receiving window 13, and the annular sealing ring 23 is fitted in the gap. A sealing agent is applied, and caulking rings 24 are caulked around the lower edges of the outer wall 10, the sealing ring 23, and the inner wall 11. It should be noted that air bubbles are made to exist when the heat storage edge agent 15 is enclosed so as to correspond to the volume change at the time of liquid-solid phase transformation. The body 2 is formed in this way. The device can also be applied to a disposable oil filter. In that case, the opening 9 of the body 2, that is, the bolt holes 20, 21 of FIG. 2 are not provided.

この考案のオイルフィルタは容器の2重壁内に封入した蓄熱剤が、オイルの流 入圧力を検知して、固化発熱し、高温で液化して常温に至っても液相を保ってい るので、外部からの配管や配線が不要であり、取付けスペースの選定上有利であ る。またオイルフィルタ装着の際、配管や配線に接続する面倒な作業が不要であ る。さらに常時の使用にあたり、加熱媒体や熱源エネルギの送入・停止の制御が 不要で、オイルフィルタ自体に自己制御させ、循環サイクルで継続的に作動させ られるから甚だ便利である。 In the oil filter of this invention, the heat storage agent enclosed in the double wall of the container detects the inflow pressure of the oil, solidifies and generates heat, and liquefies at a high temperature to maintain a liquid phase even when it reaches room temperature. No external piping or wiring is required, which is advantageous in selecting the installation space. Also, when installing the oil filter, troublesome work for connecting to piping and wiring is not required. In addition, it is extremely convenient to use it at all times because it does not need to control the heating medium or heat source energy supply / stop, and allows the oil filter itself to self-control and continuously operate in the circulation cycle.
