ABSTRACT:
An oil drain valve assembly is provided for draining oil from an engine crankcase such as in a small internal combustion engine. The drain valve assembly includes an adaptor, an outer sleeve assembly, and interlocking for permitting opening of the valve assembly by relatively limited counter-clockwise rotation and subsequent pulling of the outer sleeve assembly relative to the adaptor. The interlocking means is formed of a pair of diametrically opposed J-slots disposed on the upper end of the outer sleeve assembly and co-mating locking pins disposed on the exterior surface of the adaptor. The locking pins are engageable with detents formed on the J-shaped slots to define a closed or sealed position.
