一般の潤滑油濾過器は、第１図に示すように、円筒状の
濾過材１０の一端に設けられた流入口１１から潤滑油が
圧入され、他端に設けられた安全弁２０がバネ２１によ
り常圧時は閉ざされているものである。In a general lubricating oil filter, as shown in FIG. It is closed at normal pressure.
そして潤滑油が濾過材１０を通過する際に、油中に含ま
れた異物が濾過清浄され、時間経過とともに摩滅により
発生する金属粉等が濾過材１０に蓄積されて目づまりを
生じる。When the lubricating oil passes through the filter medium 10, foreign matter contained in the oil is filtered and cleaned, and over time, metal powder and the like generated due to wear accumulate on the filter medium 10, causing clogging.
この場合、濾過材１０の内圧が上昇するので、バネ２１
の力に抗して安全弁２０が図中、上昇して開く。In this case, since the internal pressure of the filter medium 10 increases, the spring 21
The safety valve 20 rises and opens in the figure against the force of.
このように濾過材１０に目づまりが生じたときにはその
濾過材１０を新品と交換しなければならないので、安全
弁２０に連結棒３０を設け、その棒３０を筐体４０の外
部にＯリング４１を介して突出させ、その突出部に設け
られたラック３１と噛み合うピニオン３２に指針３３を
設け、指針３３の先にｒＯＫＪ、ｒＮＧＪ等の指標を設
けた警告装置が知られている。When the filter material 10 becomes clogged in this way, it is necessary to replace the filter material 10 with a new one, so a connecting rod 30 is provided in the safety valve 20 and the rod 30 is connected to the outside of the casing 40 via an O-ring 41. A warning device is known in which a pointer 33 is provided on a pinion 32 that protrudes from the pinion 32 and meshes with a rack 31 provided on the protruding portion, and an index such as rOKJ, rNGJ, etc. is provided at the tip of the pointer 33.
すなわち、濾過材１０の内圧が常圧のとき （濾過性能
が良好のとき）には第１図に示すように指針３３が「Ｏ
Ｋ」を指し、濾過材１０の内圧が高くなったとき（濾過
不能になったとき）には安全弁２０が上昇してピニオン
３２が回転するので指針３３がｒＮＧＪを指す。That is, when the internal pressure of the filter medium 10 is normal pressure (when the filtration performance is good), the pointer 33 is set to "O" as shown in FIG.
When the internal pressure of the filter medium 10 becomes high (filtration becomes impossible), the safety valve 20 rises and the pinion 32 rotates, so the pointer 33 points to rNGJ.
結局、上記従来装置は、濾過材１０が濾過不能になった
ことを機械的に検出しているので、指針３３を筐体４０
から余り離れて設置することができない。In the end, the conventional device mechanically detects that the filtering material 10 is no longer able to filter, so the pointer 33 is moved toward the housing 40.
It cannot be installed too far away from the

警告装置も座席の下近傍に設置されることになる。Furthermore, in automobiles, the filter material 10 is often installed under the seat, so the pointer 33, that is, the clogging warning device, is also installed near the bottom of the seat.
したがって運転者にとって、その目づまり警告装置が兄
にくく、目づまりの発見が遅れるという問題点がある。Therefore, there is a problem in that the clogging warning device is difficult for the driver to use, and the detection of the clogging is delayed.
また、濾過材１０の目づまりに気づかずに濾過材１０を
破損してしまった場合には、濾過材１０の内圧が高くな
ることはなくなるので、指針３３は「ＯＫ」を指すこと
になり、濾過材１０の破損に気づかないおそれがある。In addition, if the filter medium 10 is damaged without noticing that the filter medium 10 is clogged, the internal pressure of the filter medium 10 will not increase, so the pointer 33 will point to "OK" and the filter There is a possibility that damage to the material 10 may not be noticed.
そこで本考案は、濾過器に目づまりを生じたことを確実
に運転者に知らせ、適切な時期に濾過材を交換すること
