れる。 Further, the discharge oil passage 9 is connected to an oil supply rod oil passage 59 in the oil supply rod 52 via an adapter oil passage 60 shown in FIG. 2 by an oil supply pipe (not shown). The tip of this oiling rod 52 is screwed into the cylinder liner 51. A cylinder jacket 53 is provided on the outside of this cylinder liner, and the cylinder liner 51 and cylinder jacket 53 constitute a cooling water chamber 54. This cooling water chamber 5
The cylinder liner 51 is cooled by the cooling water in the cylinder liner 4.

上限が規制される。 Further, the cylinder liner 51 is provided with a lubricating hole 55, to which an lubricating rod oil passage 59 is connected via a lubricating rod check valve 56. The lubricating rod check valve 56 is biased in the closing direction by a check valve spring 57, and the upper limit of the valve opening amount is regulated by a check valve spout 58.
上述の構成により、第１図に示すようなカム１
の最大リフト位置において、吐出逆止弁６，７お
よび注油棒５２の注油棒逆止弁５６はすべて閉
じ、注油棒５２からの注油が完了する。この際の
注油棒油路５９内の圧力は、注油棒逆止弁５６の
閉弁圧およびシリンダ内の圧力によつて決まる。 With the above configuration, the cam 1 as shown in FIG.
At the maximum lift position, the discharge check valves 6, 7 and the oil rod check valve 56 of the oil filler rod 52 are all closed, and the oil filling from the oil filler rod 52 is completed. The pressure within the oil supply rod oil passage 59 at this time is determined by the closing pressure of the oil supply rod check valve 56 and the pressure within the cylinder.
さらにカム１が回転し、プランジヤ４が下降し
始めると、吸入弁１０，１１が開き潤滑油１８が
ストレーナー１４およびサクシヨンパイプ１３を
通してプランジヤ４の上面に吸入される。 When the cam 1 further rotates and the plunger 4 begins to descend, the suction valves 10 and 11 open and the lubricating oil 18 is sucked into the upper surface of the plunger 4 through the strainer 14 and suction pipe 13.
そして、カム１が回転してプランジヤ４が上昇
し始めると、プランジヤ４上面の圧力が上がり、
吸入弁１０，１１が閉弁する。さらにプランジヤ
４上面の圧力が上がると、吐出逆止弁６，７が開
き、潤滑油１８は注油棒５２へ送給される。もつ
と圧力が上がつて注油棒逆止弁５６の開弁圧に達
すると、注油棒逆止弁５６が開き、シリンダへ注
油される。 Then, when the cam 1 rotates and the plunger 4 begins to rise, the pressure on the top surface of the plunger 4 increases,
Suction valves 10 and 11 are closed. When the pressure on the upper surface of the plunger 4 further increases, the discharge check valves 6 and 7 open, and the lubricating oil 18 is fed to the oil filler rod 52. When the pressure gradually increases and reaches the opening pressure of the oil filler rod check valve 56, the oil filler rod check valve 56 opens and the cylinder is filled with oil.
その後、カム１の最大リフト位置まで注油が行
なわれ、第１図に示す状態に戻る。この繰返しに
より注油が行なわれる。 Thereafter, lubrication is performed until the cam 1 reaches its maximum lift position, and the state shown in FIG. 1 is returned to. Lubrication is performed by repeating this process.
プランジヤ４の動きをピストンの動きと対応さ
せてシリワダ内のピストンのある一定位置でのみ
適量の潤滑油１８の注油を行なうことにより、潤
滑作用の効率を向上させることができる。 By making the movement of the plunger 4 correspond to the movement of the piston and applying an appropriate amount of lubricating oil 18 only at a certain position of the piston in the sifter, the efficiency of the lubrication effect can be improved.
したがつて、ピストン、ピストンリング、シリ
ンダライナの摩耗、焼付等を確実に防止すること
がき、しかも潤滑油１８の消費を減少させること
ができる。 Therefore, wear, seizure, etc. of the piston, piston ring, and cylinder liner can be reliably prevented, and consumption of lubricating oil 18 can be reduced.
しかしながら、従来のシリンダ注油器において
は、注油終了後の注油棒油路５９内の圧力は、注
油棒逆止弁５６の閉弁圧とシリンダ内の圧力によ
つて決まる。注油棒逆止弁５６のようなボール弁
式逆止弁の開弁圧Poおよび閉弁圧Pcは、逆止弁
ばね５７のばね力とボール弁の受圧面積とにより
決まるが、開弁圧Poと閉弁圧Pcとはほぼ等しい。 However, in the conventional cylinder lubricator, the pressure in the lubricant rod oil passage 59 after lubricating is completed is determined by the closing pressure of the lubricant rod check valve 56 and the pressure inside the cylinder. The opening pressure Po and closing pressure Pc of a ball valve type check valve such as the lubricating rod check valve 56 are determined by the spring force of the check valve spring 57 and the pressure receiving area of the ball valve. and the valve closing pressure Pc are almost equal.
また、シリンダ注油器のように注油棒逆止弁５
６にシリンダ内圧力Pcylが作用する場合の開弁
圧Po1およびPc1は、開弁圧Po、閉弁圧Pcにシリ
ンダ内圧力Pcylが付加されたものとする。すな
わち、
Po1＝Po＋Pcyl
Pc1＝Pc＋Pcyl
となる。 Also, like a cylinder lubricator, the lubricating rod check valve 5
The valve opening pressures Po 1 and Pc 1 when the cylinder internal pressure Pcyl acts on the cylinder pressure Pcyl are assumed to be the cylinder internal pressure Pcyl added to the valve opening pressure Po and the valve closing pressure Pc. That is, Po 1 = Po + Pcyl Pc 1 = Pc + Pcyl.
注油終了時のシリンダ内圧力をPcyl1とすると、
注油棒逆止弁５６が閉じた際の注油棒油路５９内
の圧力はPc11＝Pc＋Pcyl1であり、その後まもな
く吐出逆止弁６，７も閉じるので、注油棒油路５
９内の圧力はPc11より少し低い圧力P2に保たれ
る。 If the cylinder pressure at the end of lubrication is Pcyl 1 ,
The pressure inside the oil rod oil passage 59 when the oil oil rod check valve 56 is closed is Pc 11 =Pc + Pcyl 1 , and the discharge check valves 6 and 7 are also closed shortly thereafter, so the oil oil passage 59 is closed.
The pressure inside 9 is maintained at a pressure P2 , which is slightly lower than Pc11 .
注油終了時のシリンダ内圧力Pcyl1が高く、注
油終了後のシリンダ内圧力Pcylが低下すると、
注油棒逆止弁５６の開弁圧Po1も下がる。 If the cylinder pressure Pcyl 1 at the end of lubrication is high and the cylinder pressure Pcyl 1 after the end of lubrication decreases,
The opening pressure Po 1 of the oil filler rod check valve 56 also decreases.
一方、注油棒油路５９内の圧力は、P2という
高い圧力に保持されているので、Po1がP2よりも
小さくなると、再び注油棒逆止弁５６が開弁して
しまい、注油が行なわれてしまう。 On the other hand, the pressure inside the oil supply rod oil passage 59 is maintained at a high pressure of P2 , so when Po1 becomes smaller than P2 , the oil supply rod check valve 56 opens again, and the oil supply is stopped. It will be done.
すなわち、第３図に示すように注油棒油路５９
内圧力が上昇すると、その際の開弁圧Po11を越え
て、注油棒逆止弁５６の開弁Ａが起こる。 That is, as shown in FIG.
When the internal pressure increases, it exceeds the valve opening pressure Po 11 at that time, and the oil filler rod check valve 56 opens A.
つぎに、注油棒油路５９内の圧力が減少して閉
弁圧Pc11より低くなると、注油棒逆止弁５６が閉
弁する。しかし、注油棒油路５９内の圧力は、
P2までしか下降しない。 Next, when the pressure in the oil supply rod oil passage 59 decreases and becomes lower than the valve closing pressure Pc11 , the oil supply rod check valve 56 closes. However, the pressure inside the oil filler oil passage 59 is
It only descends to P2 .
したがつて、注油孔５５の位置でのシリンダ内
圧力が減少して、開弁圧Po1が低下すると、再度
開弁Ｂが起こつてしまうのである。 Therefore, when the cylinder internal pressure at the position of the oil filling hole 55 decreases and the valve opening pressure Po 1 decreases, the valve opening B occurs again.
このように、予定されていない注油が行なわれ

率が低下することになる。したがつて、ピスト

防止するのに必要な潤滑油の量が増加してしまう
という問題点がある。 If unscheduled lubrication is performed in this way, it becomes impossible to lubricate the optimum amount of lubrication at the optimum piston position, resulting in a decrease in the efficiency of lubricating oil use. Therefore, there is a problem in that the amount of lubricating oil required to prevent wear and seizure of the piston, piston ring, cylinder, etc. increases.
本発明は、このような問題点を解決しようとす

いる。 As shown in FIGS. 4 to 6, a discharge check valve 21 is provided in the discharge oil passage 9 at the upper part of the plunger 4. As shown in FIGS.
吐出逆止弁２１の下部２１ａは、第６図に示す
ように十字形の断面を有しており、吐出逆止弁弁
座２３の内面に沿つて、吐出逆止弁２１が上下に
摺動するように構成されている。 The lower part 21a of the discharge check valve 21 has a cross-shaped cross section as shown in FIG. 6, and the discharge check valve 21 slides up and down along the inner surface of the discharge check valve seat 23. is configured to do so.
また、吐出逆止弁２１上部２１ｂは、吐出逆止

閉鎖するような作用を行なうものである。 Further, a suction return collar portion 22 is provided in the middle portion of the discharge check valve 21 . This suction return collar portion 22 is configured to cut off the oil passage within the discharge check valve seat 23 when the discharge check valve 21 is lowered. In other words, the suction return collar portion 22 provided at the middle portion of the discharge check valve 21 is
Discharge check valve seat 23 on which discharge check valve 21 is disposed
The discharge check valve 21 is slidably fitted into the oil passage inside the valve.
The oil passage is opened from the maximum lift to a predetermined lift, and is closed below the predetermined lift.
なお、吐出逆止弁２１は、逆止弁ばね２４によ

すようにシリンダ内圧力が高いので、注油棒逆止
弁５６の閉弁圧も高く、したがつて注油棒油路５
９（第２図参照）内の圧力も高くなつている。 With the above-described configuration, the plunger 4 rises to fill the cylinder with lubricating oil 18, and when the cam 1 reaches the maximum reposition position, the oil filler rod check valve 56 (see Figure 2) closes to complete the oil filling. . At this time, as shown in FIG. 7, since the cylinder internal pressure is high, the closing pressure of the oil filler rod check valve 56 is also high, and therefore the oil filler rod oil passage 5
9 (see Figure 2) is also increasing.

が流通しなくなる。 When the plunger 4 begins to descend after completion of oil filling, the pressure on the upper surface of the plunger 4 decreases, and the discharge check valve 21 is also urged by the check valve spring 24 and begins to descend. At this time, if the lower end of the suction collar portion 22 touches the upper edge of the inner surface of the discharge check valve seat 23,
Lubricating oil 18 is placed between the upper and lower parts of the discharge check valve 21.

の容積が、少なくとも吸いもどしカラー部２２の
分だけ増加することになる。 Therefore, there is no increase or decrease in oil in the oil passage from the discharge oil passage to the oil supply rod oil passage 59. In addition, after the lower edge of the suction return collar 22 contacts the inner surface of the discharge check valve seat 23 and before the discharge check valve 21 descends and seats on the discharge check valve seat 23, the discharge oil Road 9
The volume of this increases at least by the amount of the suction collar portion 22.
このため、注油棒油路５９内油が、その容積増
加分だけ吸いもどされることになり、注油棒油路
５９内の圧力が減少して、注油棒逆止弁５６の再
開弁が防止される。 Therefore, the oil in the oil filler rod oil passage 59 is sucked back by the increased volume, the pressure in the oil filler rod oil passage 59 decreases, and the reopening of the oil filler rod check valve 56 is prevented. .
すなわち、第７図に示すように注油棒逆止弁５
６が閉弁した後、注油棒油路５９内の圧力は減少
し、注油棒逆止弁５６は再開弁しない。 That is, as shown in FIG.
6 is closed, the pressure in the oil filler rod oil passage 59 decreases, and the oil filler rod check valve 56 does not reopen.
このように、注油棒逆止弁５６の再開が確実に
防止されるので、最適なピストン位置のみで適量
