Abstract

An oil supply device has a reservoir adapted to contain oil having a predetermined oil level; a drive shaft extending into the reservoir; a disc affixed to the shaft and being arranged to be submerged at least partially in the oil contained in the reservoir; and a trough affixed to the disc for rotation therewith as a unit. The trough extends arcuately and is radially inwardly open as viewed relative to the disc. Further, the trough is arranged to be submerged at least partially in the oil contained in the reservoir. There is also provided an oil conduit having a stationarily supported terminal portion accommodated in the reservoir and projecting into the trough. The oil conduit is provided with an open end situated in the trough and oriented opposite an operational rotary direction of the disc, whereby oil is driven into the terminal portion through the open end from the trough upon rotation of the drive shaft to supply oil under pressure in the oil conduit.
