СГОРАНИЯCombustion

1one

Изобретение относитс к машиностроению и может быть использовано в двигател х внутреннего сгорани .The invention relates to mechanical engineering and can be used in internal combustion engines.

Известны системы смазки двигател внутреннего сгорани , содержащие последовательно соединенные масл ный карьер, масл ный насос, маслоочиститель, главную масл ную магистраль, узлы трени двигател и электромаслозакачивающий насос предпусковой прокачки масла, св занный с масл ным картером и соединенный через электрический привод с управл ющим устройством 1.Lubrication systems for an internal combustion engine are known, comprising a series-connected oil pit, an oil pump, an oil cleaner, a main oil line, engine friction units and an electro-oil pumping pump for starting up the oil, which is connected to the oil pan through an electric drive. one.

Недостатком известных систем смазки вл етс ухудшение условий смазки при падении давлени в главной масл ной магистрали .A disadvantage of the known lubrication systems is the deterioration of the lubrication conditions with a pressure drop in the main oil line.

Цель изобретени - улучшение условий смазки.The purpose of the invention is to improve lubrication conditions.

Указанна цель достигаетс тем, что управл ющее устройство дополнительно подключено к главной масл ной магистрали.This goal is achieved by the fact that the control device is additionally connected to the main oil line.

Кроме того, управл ющее устройство снабжено мембраной, соединенной через шток с контактами электромаслозакачивающего насоса предпусковой прокачки масла .In addition, the control unit is equipped with a diaphragm connected via a rod to the contacts of an electro-oil pumping pump for starting up the oil pumping.

На чертеже изображена схема предлагаемой системы смазки.The drawing shows a diagram of the proposed lubrication system.

Система смазки содержит масл ный картер 1, двухсекционный масл ный насос 2, перва секци 3 которого через масл ный радиатор 4 св зана с масл ным картером 1. Втора секци 5 масл ного насоса 2 через маслоочиститель 6 и главную масл ную магистраль 7 св зана с узлами 8 трени .The lubrication system contains an oil crankcase 1, a two-piece oil pump 2, the first section 3 of which is connected through the oil cooler 4 to the oil crankcase 1. The second section 5 of the oil pump 2 via the oil cleaner 6 and the main oil line 7 is connected to knots 8 friction.

Электромаслозакачивающий насос 9 пред10 пусковой прокачки масла св зан масл ным картером I и соединен через электрический привод 10 с управл ющим устройством 11.The electric oil pumping pump 9 for pre-starting oil pumping is connected by an oil sump I and connected via an electric drive 10 to a control device 11.

15 Управл ющее устройство 11 дополнительно подключено к главной масл ной магистрали 7 трубопроводом 12 и снабжено мембраной 13, соединенной через шток 14 с контактами 15 и 16 электромаслозакачивающего насоса 9 предпусковой прокачки 15 The control device 11 is additionally connected to the main oil line 7 by a pipe 12 and is equipped with a membrane 13 connected via a rod 14 to contacts 15 and 16 of the electro-oil pumping pump 9 of the starting pumping

20 масла.20 oils.

Claims

When the engine is operating, in the event of a pressure drop in the main oil line 7, the membrane 13 of the control device 11 deforms. The deformation is transmitted to the rod 14, during its movement the contacts 15 and 16 are closed, as a result of which the oil-pumping pump 9 starts additionally supplying oil to the surfaces of the engine 8, in addition to supplying the second section 5 of the two-part oil pump 2 with oil. This increases the oil consumption going to lubricate the lubricants surfaces of the engine 8, and increases the oil pressure in the main oil line 7, which normalizes the work surfaces of the engine 8. Putting into operation of the lubrication system of an electric oil charging pump prestarting oil pumping when the engine is running in case of a pressure drop in the main oil line allows stabilizing the oil pressure in it and thereby improve the lubrication conditions, which reduces wear on the engine's rubbing surfaces. Claims 1. An internal combustion engine lubrication system comprising a series-connected oil sump, an oil pump, an oil cleaner, a main oil line, engine friction assemblies and an electric oil pumping oil starting pump connected to the oil sump and connected through an electric drive a control device, characterized in that, in order to improve the lubrication conditions, the control device is additionally connected to the main oil line.

2. A system according to claim 1, characterized in that the control device is equipped with a diaphragm connected via a rod to the contacts of an electrostatic pumping pump for starting the pumping of oil.
