Description
【発明の詳細な説明】 本発明は内燃機関のシリンダライナ潤滑装置に関する。[Detailed description of the invention] The present invention relates to a cylinder liner lubrication system for an internal combustion engine.
ディーゼル機関のシリンダライナの潤滑油の供給方式と

関のあるピストン位置でのみ注油すべく構成されたもの
を定時注油装置という。As a method of supplying lubricating oil to the cylinder liner of a diesel engine, a method of filling oil through an oil hole provided in the cylinder liner is used for medium to large-sized engines. Among these, a device configured to lubricate only certain piston positions in two engines is called a periodic lubrication device.
全体の構成は第１図に示され、１０００はカム駆動のフ

レバーで。The overall configuration is shown in FIG. 1, where 1000 is a cam-driven flange pump type oiler, 2000 is a oiler valve equipped with a check valve, and 3000 is a pipe connecting the two. FIG. 2 shows details of the lubricator 1000. 1 is the oiler body, which is filled with oil. A cam 2 is reversely driven by a gear or the like to rotate in synchronization with the rotation of the crankshafts of the two engines. 3 is the metering lever.

ャで、調量レバー３を介してカム２によシ上下動する。It is supported by the main body work at a fulcrum 31. 32 is a loan that is in contact with the cam 2; 33 is a portion that is in contact with a plantain, which will be described later;
4 is a portion that comes into contact with a metering screw, which will be described later. A plunger 4 is moved up and down by the cam 2 via the metering lever 3.

ある。40 is an oil chamber in the upper part of the syringe, and 5 is a plunger guide which is attached to the main body 1. 6 is a suction valve, 7 is a discharge valve, 8
9 is a float-type flowmeter, and 9 is a joint that connects to pipe 3'OOO.
１０は調量ねじで、調量レバー３がブランツヤ４を下げ
る作用を制限する。10 is a metering screw which limits the action of the metering lever 3 to lower the blunt gloss 4.

ンツヤ４上部の油が圧縮され。As the cam 2 rotates, the gap with the roller 32 disappears, and as the cam 2 rotates further, the metering rod 3 rotates and the portion 33 pushes up the plunger 4. Then, the oil at the top of Plantsuya 4 is compressed.

とができる。Open the discharge valve 7 and connect the lubrication valve 2 via the via 03000.
000, oil is supplied from an oil supply hole in the cylinder liner (not shown). Lubricating ends when the cam 2 pushes the planter 4 upward most via the metering gear 3. When the cam 2 further rotates, the blank 14 moves downward, so the pressure in the upper part of the gland decreases, and at the same time the discharge valve 7 closes, the suction valve 6 opens to suck in the oil inside the main body. Suction continues while plunger 4 is lowered, but metering
When the portion 4 contacts the metering screw 10, the metering lever 3 no longer moves even if the cam 3 rotates, so the plunger 4 also does not move, and the suction ends. Further rotation will result in the next lubrication cycle, but the amount of lubrication will be equal to the amount of oil sucked in so far. By the way, when the metering screw 10 is rotated, the timing at which the portion 34 of the metering lever comes into contact with the metering screw 10 changes, so the amount of suction changes, and therefore the amount of lubrication can be changed.
しかし上記のものには次の欠点がある。However, the above method has the following drawbacks.

するにはカムが大形化してコストアップとなる。It is said that the best lubrication effect can be obtained with the minimum amount of oil by applying regular lubrication to the upper part of the cylinder during the ascent process of the piston, and spreading the lubricating oil to the entire surface of the cylinder liner through the piston rings. However, if you start lubricating when the piston is far down, it will spread irregularly due to its own weight and the vibration of the piston ring before the piston ring expands, and you will not be able to obtain a uniform and evenly spread out oil. We would like to shorten the period as much as possible, but this was difficult with conventional methods. In other words, if the flanger diameter is increased, the lubrication period (r; 1. becomes.

とである。The object of the present invention is to focus on the above points, and to provide a lubricating device that can shorten the lubrication period and achieve efficient lubrication, that is, obtain the best lubrication effect with the minimum amount of lubricant. The reason for this is that in the cylinder lychee lubricating system, in which lubricating oil is pumped by a plunger that is reversely driven by a cam interlocked with the crankshaft of two engines and slides on the inner circumferential surface of the syringe guide, there is a An oil passage having the other end opened in the outer peripheral surface of the plunger in the upper oil chamber of the plunger, and an opening on one end side provided in the plunger guide and communicating with the opening in the outer peripheral surface of the upper plunger when the plunger is lifted in a predetermined manner. The inner peripheral surface of the guide is provided with oil passages each having an opening on the other end formed as an oil reservoir.

期間を短縮させることができる。In this case, the lubrication period can be shortened by using the faster part of the cam by ending the lubrication stroke of the pusher with the opening of the lubrication end hole that is opened to stop the compression of the pump. Can be done.
以下図面を参照して本発明による実施例にっき説明する
。Embodiments of the present invention will now be described with reference to the drawings.
第３図は本発明による１実施例の装置の要部を示す断面

その長さ方向の途中に板状溝４１があり、油路４２．４
３によってプランツヤ上部油室４ｏに結ばれている。4' is smooth and the length and outer diameter are not particularly different, but
There is a plate-shaped groove 41 in the middle of the length direction, and the oil passage 42.4
3 is connected to the oil chamber 4o in the upper part of the plant.

is installed.
油路５１の開口位置は、プランジャ摺動面で。The opening position of the oil passage 51 is on the plunger sliding surface.

The location shall not be in direct communication with the The oil passage 52 connects the oil passage 51 and the inside of the main body 1.
環状溝４１はプランツヤ４′のストロークの途中で油路
５１と連絡するものとする。It is assumed that the annular groove 41 communicates with the oil passage 51 in the middle of the stroke of the planter 4'.
上記構成の場合の作用について述べる。The operation in the case of the above configuration will be described.

。The cam rotates and the metering lever touches the roller, causing the plant to rotate 4'.
It is the same as the conventional one until it is pushed up. It is also the same as the conventional method in that the cylinder gloss 4' is raised, the discharge valve 7 is opened, and the cylinder is filled with oil from a lubricating valve (not shown) via a pipe (not shown). When the plunger 4' continues to move forward, the annular groove 41 and the oil passage 51 communicate with each other. Therefore, the upper oil chamber 40 of the plunger communicates with the inside of the lubricator body, and therefore, the plunger 4' remains in contact with the oil passage 51 even though the plunger 4' moves upward. The pressure in the upper oil chamber 40 drops, the discharge valve 7 closes, and the oil filling ends. In addition.
このよう−に注油路シは従来のものよシ早期となるため
、調量ねじ１０を調整して早い時期、から注油を始める
必要がある。In this way, since the oil supply path is filled earlier than in the conventional case, it is necessary to adjust the metering screw 10 and start oil supply at an earlier stage.
上述の場合には次の効果がある。The above case has the following effects.

Start lubricating more. In this case, since the lubricator 9 is used at a location where the cam speed is faster than that of the conventional one, the lubricant period is greatly shortened to θ'cB:l), θ'd<θd.

ライナの摩耗を少すくできる。Therefore, unlike conventional methods, lubrication can be started when the piston rises, preventing the lubricating oil from spreading irregularly due to its own weight or vibration, and the piston ring allows it to spread reliably, so the piston ring can be filled with the minimum amount of oil. , the wear on the cylinder liner can be reduced.

ものである。42 and 43 are oil passages, 43 opens on the outer peripheral surface of the plunger 4'', and 42 connects the oil passage 43 and the plunger upper oil chamber.
５３はプランツヤ案内に設けられた環状溝で。53 is an annular groove provided in the plant gear guide.

状溝４１と油路５Ｉの連絡タイミングと同一である。The communication timing between the annular groove 53 and the oil passage 43 is the same as the communication timing between the annular groove 41 and the oil passage 5I in FIG. 3.
従って２作用、効果は同−丁ある。Therefore, the two effects and effects are the same.
