The oil is fed to the speed governor and airscrew as follows.
Oil from the airscrew shaft apace is supplied through the longitudinal receaa on the airscrew shaft plug
surface and radial hole in the airscrew shaft and spacer to the rear annular space formed by the oil transfer
bushing. From the annular space the oil flows through the passage in the gearbox housing, mesh filter at the
governor inlet to the speed governor.
Oil is delivered from the speed governor to the airscrew and back from the latter to the apeed governor
through the same route.
With the engine running, oil from the governor is fed to the airscrew and back through the passage in
the gearbox housing, which connects the speed governor with the front annular space of the oil transfer
buahing. From this space oil is delivered through radial holes in the spacer and airscrew shaft to the
longitudinal hole in the airscrew shaft plug and then to the airscrew cylinder.
Oil flowing out from the gaps between friction surfaces of the gearbox parta as well as from the timing
mechanism drains down to the oil sump.
Oil from the spaces of the intermediate crankcase, mixture collector and rear cover also flows to the oil
sump.
The oil is sucked through the filter with chip detector located in the lower front part of the oil sump,
passages of the oil sump, mixture collector and crankcase rear cover by the scavenging section of the oil pump
and is fed further through the oil cooler to the oil tank.
During operation of the engine certain amount of gases penetrates from the combustion chamber
through the gaps between the piston rings and cylinder sleeves to the crankcaae, besides, oil contained in the
crankcase partially evaporates owing to high temperature.
The blow-by gases and oil vapour increase pressure inside the crankcase which may lead to oil
leakage through the crankcase joints.
To equalize the pressure between the engine crankcase cavities they are interconnected by the
breathing holes and to equalize the pressure inside the crankcase with the atmospheric pressure the engine is
equipped with two breathing holes, one of which is located in the gearbox housing, and the other on the mixture
collector. These holes are connected with the breathing system of the airplane.
Provided in the lower front part of the oil sump is a flange with two studs and a hole which serves for
providing airplane breathing during inverted flight.
