2.13.1. Features of the device

Fig. 2.65. Lubrication system: 1 – the channel in the block of cylinders for supply of oil to the oil highway of a head of cylinders; 2 – the channel in a head of cylinders; 3 – a branch pipe of removal of crankcase gases in the case of the air filter; 4 – cover of an oil-filling mouth; 5 – branch pipe of an exhaust hose; 6 – a branch pipe of removal of crankcase gases in zadrosselny space of the carburetor; 7 – the oil highway in a head of cylinders; 8 – camshaft; 9 – the channel of supply of oil to the camshaft bearing; 10 – sensor of a control lamp of pressure of oil; 11 – reducing valve; 12 – the channel of supply of oil from the filter to the trunk oil main; 13 – leading gear wheel of the oil pump; 14 – the conducted gear wheel of the oil pump; 15 – the channel of supply of oil from the pump to the filter; 16 – antidrainage valve; 17 – the filtering cardboard element; 18 – oil case; 19 – oil receiver; 20 – drain stopper; 21 – perepuskny valve; 22 – oil filter; 23 – the channel of supply of oil from the radical bearing of a bent shaft to conrod; 24 – the channel of supply of oil to the radical bearing of a bent shaft; 25 – trunk oil main

The device of the lubrication system is shown in fig. 2.65.
The lubrication system combined. Under pressure radical and conrod bearings of a bent shaft, camshaft support are greased; spraying — walls of cylinders, pistons with piston rings, piston fingers, camshaft cams, pushers and cores of valves.
At pressure drop of oil is lower than admissible the control lamp of insufficient pressure of oil lights up.

Fig. 2.66. Details of the oil pump: 1 – pump housing; 2 – the conducted gear wheel; 3 – leading gear wheel; 4 – reducing valve; 5 – spring of the reducing valve; 6 – stopper; 7 – sealing ring; 8 – forward epiploon of a bent shaft; 9 – pump cover; 10 – rubber sealing ring; 11 – oil receiver

The oil pump (fig. 2.66) gear, with gear wheels of 2 and 3 internal gearings settles down at a forward end face of the block of cylinders. The leading gear wheel 3 oil pumps is established on two lyska on the forward end of a bent shaft. For reduction of mechanical losses of a gear wheel have trokhoidalny gearing. The oil receiver 11 fastens bolts to a cover of the second radical bearing and to the case of 1 pump.
