摘要： Breather apparatus is disclosed for relieving engine crankcase pressure when the engine is tipped or rotated. The breather apparatus consists of a duct intake connected to the crankcase, an elongated duct, and a drain hole for draining oil back into the crankcase. The duct intake should be positioned in an area of low oil splash. The drain hole should be positioned so that it is not submerged in oil while being tipped 90.degree. in either a clockwise or a counter-clockwise direction about the engine's vertical centerline. The breather assembly is particularly suitable for lawnmowers that are tipped during cleaning.
