Description

本発明は、内燃機関、特に大型ディーゼル機関、好適には船舶用ディーゼル機関のシリンダの内周面に潤滑油を強制注油するシリンダ注油装置に関するものである。   The present invention relates to a cylinder lubrication device that forcibly lubricates an inner peripheral surface of a cylinder of an internal combustion engine, particularly a large diesel engine, preferably a marine diesel engine.

船舶用ディーゼル機関のシリンダの内周面に潤滑油を強制注油するシリンダ注油器（以下、「シリンダ注油装置」という。）としては、例えば、特許文献１に開示されたものが知られている。   As a cylinder lubricator (hereinafter referred to as “cylinder lubrication device”) that forcibly lubricates the inner peripheral surface of a cylinder of a marine diesel engine, for example, one disclosed in Patent Document 1 is known.

しかしながら、上記特許文献１に開示されたシリンダ注油装置では、流量調整弁１８の弁開度を手動で調整し、流量調整弁１８を通過する油圧作動流体の流量を調整して、これによりピストン１０すなわちプランジャ１１の速度を調整し、注油速度（注油期間：注油時間）を調整するようにしている。すなわち、上記特許文献１に開示されたシリンダ注油装置では、内燃機関の回転数に応じて流量調整弁１８の弁開度をその都度手動で調整することは実質不可能であり、内燃機関の回転数に対して適切な注油期間に制御（注油）できないといった問題点があった。   However, in the cylinder lubrication device disclosed in Patent Document 1, the valve opening degree of the flow rate adjusting valve 18 is manually adjusted, and the flow rate of the hydraulic working fluid passing through the flow rate adjusting valve 18 is adjusted. That is, the speed of the plunger 11 is adjusted to adjust the oiling speed (oiling period: oiling time). That is, in the cylinder lubrication device disclosed in Patent Document 1, it is virtually impossible to manually adjust the valve opening degree of the flow rate adjusting valve 18 each time according to the rotational speed of the internal combustion engine. There was a problem that control (lubrication) was not possible during the lubrication period appropriate for the number.

本発明は、上記の事情に鑑みてなされたもので、内燃機関の回転数に応じて注油速度（注油期間：注油時間）を自動で調整することができるシリンダ注油装置を提供することを主たる目的とする。   The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a cylinder lubrication device capable of automatically adjusting the lubrication speed (the lubrication period: the lubrication time) according to the rotational speed of the internal combustion engine. And

本発明は、上記課題を解決するため、以下の手段を採用した。
本発明に係るシリンダ注油装置は、枝管の途中に設けられた電磁弁が開くと、リリーフ弁ユニットにて調圧された潤滑油主管内の潤滑油が、前記枝管を介して注油器のシリンダに導かれ、前記注油器内に設けられたピストンおよびプランジャを押し上げ、前記プランジャを収容するシリンダ内に満たされていた潤滑油が、注油管、および内燃機関のシリンダに設けられたシリンダ注油口を介して内燃機関のシリンダとピストンとの間に注入されるシリンダ注油装置であって、前記リリーフ弁ユニットは、前記内燃機関の回転数に応じて、前記内燃機関の回転数が低い時には、前記潤滑油主管内の潤滑油の圧力が低く、前記内燃機関の回転数が高い時には、前記潤滑油主管内の潤滑油の圧力が高くなるように、前記潤滑油主管内の潤滑油の圧力を直線状あるいは階段状に、かつ、自動的に変化させる油圧回路からなる。 The present invention employs the following means in order to solve the above problems.
When the solenoid valve provided in the middle of the branch pipe is opened, the lubricating oil in the lubricating oil main pipe regulated by the relief valve unit is supplied to the cylinder lubricating apparatus according to the present invention via the branch pipe. Lubricating oil led to the cylinder and pushed up the piston and plunger provided in the lubricator, and filled in the cylinder that accommodates the plunger is lubricated, and a cylinder lubrication port provided in the cylinder of the internal combustion engine The cylinder lubrication device is injected between the cylinder and the piston of the internal combustion engine via the internal combustion engine, and the relief valve unit is configured such that when the rotational speed of the internal combustion engine is low according to the rotational speed of the internal combustion engine, The pressure of the lubricating oil in the lubricating oil main pipe is such that when the pressure of the lubricating oil in the lubricating oil main pipe is low and the rotational speed of the internal combustion engine is high, the pressure of the lubricating oil in the lubricating oil main pipe is high. Straight or stepped, and consists of a hydraulic circuit for automatically changing.

本発明に係るシリンダ注油装置によれば、内燃機関の回転数に応じて、内燃機関の回転数が低い時には、潤滑油主管内の潤滑油の圧力が低く、内燃機関の回転数が高い時には、潤滑油主管内の潤滑油の圧力が高くなるように、潤滑油主管内の潤滑油の圧力を直線状あるいは階段状に、かつ、自動的に変化させる油圧回路からなるリリーフ弁ユニットを具備しているので、内燃機関の回転数に応じて注油速度（注油期間：注油時間）を自動で調整することができる。   According to the cylinder lubrication device of the present invention, when the rotational speed of the internal combustion engine is low according to the rotational speed of the internal combustion engine, the pressure of the lubricating oil in the lubricating oil main pipe is low, and when the rotational speed of the internal combustion engine is high, A relief valve unit comprising a hydraulic circuit that automatically changes the pressure of the lubricating oil in the lubricating oil main pipe linearly or stepwise and automatically so that the pressure of the lubricating oil in the lubricating oil main pipe increases. Therefore, the oiling speed (oiling period: oiling time) can be automatically adjusted according to the rotational speed of the internal combustion engine.

本発明に係る内燃機関は、上記シリンダ注油装置を具備している。   The internal combustion engine which concerns on this invention comprises the said cylinder oil supply apparatus.

本発明に係る内燃機関によれば、内燃機関の回転数が低い時には、ゆっくりとした注油速度（長きにわたる注油期間：注油時間）で注油が行われ、内燃機関の回転数が高い時には、速い注油速度（短い注油期間：注油時間）で注油が行われることになり、内燃機関の回転数に応じた適切な注油が行われることになる。   According to the internal combustion engine of the present invention, when the rotational speed of the internal combustion engine is low, lubrication is performed at a slow lubrication speed (long lubrication period: lubrication time), and when the rotational speed of the internal combustion engine is high, fast lubrication is performed. Lubrication is performed at a speed (short lubrication period: lubrication time), and appropriate lubrication according to the rotational speed of the internal combustion engine is performed.

本発明に係るシリンダ注油方法は、枝管の途中に設けられた電磁弁が開くと、潤滑油主管内の潤滑油が、前記枝管を介して注油器のシリンダに導かれ、前記注油器内に設けられたピストンおよびプランジャを押し上げ、前記プランジャを収容するシリンダ内に満たされていた潤滑油が、注油管、および内燃機関のシリンダに設けられたシリンダ注油口を介して内燃機関のシリンダとピストンとの間に注入されるシリンダ注油方法であって、前記内燃機関の回転数に応じて、前記内燃機関の回転数が低い時には、前記潤滑油主管内の潤滑油の圧力が低く、前記内燃機関の回転数が高い時には、前記潤滑油主管内の潤滑油の圧力が高くなるように、前記潤滑油主管内の潤滑油の圧力を直線状あるいは階段状に、かつ、自動的に変化させるようにした。   In the cylinder lubrication method according to the present invention, when a solenoid valve provided in the middle of the branch pipe is opened, the lubricant in the lubricant main pipe is guided to the cylinder of the lubricator via the branch pipe, and the inside of the lubricator The cylinder and the piston of the internal combustion engine are pushed up through the oil supply pipe and the cylinder oil supply port provided in the cylinder of the internal combustion engine. In which the pressure of the lubricating oil in the lubricating oil main pipe is low when the rotational speed of the internal combustion engine is low according to the rotational speed of the internal combustion engine. When the rotational speed of the lubricating oil is high, the pressure of the lubricating oil in the lubricating oil main pipe is automatically changed linearly or stepwise so that the lubricating oil pressure in the lubricating oil main pipe becomes high. .

本発明に係るシリンダ注油方法によれば、内燃機関の回転数に応じて、内燃機関の回転数が低い時には、潤滑油主管内の潤滑油の圧力が低く、内燃機関の回転数が高い時には、潤滑油主管内の潤滑油の圧力が高くなるように、潤滑油主管内の潤滑油の圧力を直線状あるいは階段状に、かつ、自動的に変化させるようにしているので、内燃機関の回転数に応じて注油速度（注油期間：注油時間）を自動で調整することができる。   According to the cylinder lubrication method according to the present invention, according to the rotational speed of the internal combustion engine, when the rotational speed of the internal combustion engine is low, the pressure of the lubricating oil in the lubricating oil main pipe is low, and when the rotational speed of the internal combustion engine is high, Since the pressure of the lubricating oil in the lubricating oil main pipe is changed linearly or stepwise and automatically so that the pressure of the lubricating oil in the lubricating oil main pipe becomes high, the rotational speed of the internal combustion engine The oiling speed (oiling period: oiling time) can be automatically adjusted according to the condition.

本発明に係るシリンダ注油装置によれば、内燃機関の回転数に応じて注油速度（注油期間：注油時間）を自動で調整することができるという効果を奏する。   According to the cylinder lubrication device of the present invention, there is an effect that the lubrication speed (the lubrication period: the lubrication time) can be automatically adjusted according to the rotational speed of the internal combustion engine.
