Abstract:
A lubricant arrangement is provided for multiple feed pipes to bearings lubrication system. In order to ensure a feed pipe remains substantially full of lubricant fluid, a drainage restrictor configuration is provided. This configuration typically comprises an anti siphon tube, accumulator, a fluid head between a supply pipe and the feed pipe as well as a final loop in the feed pipe formed by limbs. In such circumstances, drainage of lubricant fluid from other feed pipes for other bearings does not siphon lubricant fluid from the feed pipe which may be subject to potential coking as a result of high temperatures and air.
