Изобретение относитс к двигател м внутреннего сгорани .This invention relates to internal combustion engines.
Известйы двигатели внутреннего сгорани с поршн ми дл автоматического регулировани степени сжати (ПАРСС), где предусмотрены камеры переменного объема, поступление масла в которые измен ет высоту головки поршн и, следовательно, степень сжати в камере сгорани 1.Limes piston internal combustion engines for automatic control of compression ratio (PARSS), where variable volume chambers are provided, the flow of oil into which changes the height of the piston head and, consequently, the compression ratio in combustion chamber 1.
Двигатели с ПАРСС обеспечивают в определенных пределах автоматическое изменение степени сжати .Engines with PARSS provide, within certain limits, an automatic change in the degree of compression.
Однако техническое обслуживание системы регулировани оказываетс довольно трудоемким, поскольку основные ее элементы заключены- в самом поршне.However, the maintenance of the control system is rather laborious, since its main elements are enclosed in the piston itself.
Известны также шатуны переменной длины , содержащие силовой цилиндр с поршнем , образуюш,им камеру переменного объема, и стержень с маслоподвод ш,ей магистралью , каналом слива, впускным и выпускным клапанами. Впускной клапан размеш ,ен в стержне шатуна по ходу самой магистрали, а выпускной - встроен в силовой цилиндр камеры переменного объема, что упрош.ает его техническое обслуживание 2.Also known are connecting rods of variable length, containing a power cylinder with a piston, forming a variable volume chamber for them, and a rod with an oil outlet, a main line, a drain channel, inlet and exhaust valves. The inlet valve is located in the rod of the connecting rod along the line itself, and the outlet valve is integrated in the power cylinder of a variable volume chamber, which simplifies its maintenance 2.
Однако из-за размещени впускного клапана в стержне шатуна техническое обслуживание последнего в целом оказываетс , тем не менее, достаточно трудоемким, поскольку дл профилактики или замены впускного клапана все равно требуетс демонтаж шатуна .However, due to the placement of the intake valve in the connecting rod, the maintenance of the latter generally is nevertheless quite laborious, since the removal of the connecting rod is still required to prevent or replace the intake valve.
Целью изобретени вл етс упрош,ение технического обслуживани шатуна.The aim of the invention is to simplify the maintenance of the connecting rod.
Поставленна цель достигаетс тем, что впускной клапан размещен в корпусе вы10 пускйого, последний установлен в кривошипной головке шатуна, а канал слива выполнен в головке шатуна и подключен к выпускному клапану.The goal is achieved by the fact that the inlet valve is located in the high-pressure body, the latter is installed in the crank head of the connecting rod, and the drainage channel is made in the head of the connecting rod and connected to the exhaust valve.
На фиг. 1 показан шатун вместе с поршнем двигател и коленчатым валом; на FIG. 1 shows a connecting rod with an engine piston and a crankshaft; on
15 фиг. 2 - комбинированный клапан, установленный в кривошипной головке.15 of FIG. 2 - the combined valve installed in the crank head.
Шатун содержит заключенную между поршнем 1 и силовым цилиндром 2 камеру 3 переменного объема. В стержне 4 шатуна The connecting rod contains enclosed between the piston 1 and the power cylinder 2 chamber 3 of variable volume. In rod 4 connecting rod
20 выполнена масл на магистраль 5. С кривошипной головкой 6 соединен корпус 7 выпускного клапайа 8, в котором размещен впускной клапан 9. Канал 10 слива масла и канал И подвода масла выполнены в крк20 is made oil on line 5. With crank head 6, the body 7 of the exhaust valve 8 is connected, in which the inlet valve 9 is located. The channel 10 of the oil drain and the channel And the oil supply are made in Krk
