SELF-CLOSING CAP FOR THE FILLER NECK OF THE OIL PAN OF AN ENGINE

摘要

A self-closing cap for the filler neck of an oil pan is provided which allows the oil pan of an engine to be filled without the necessity of removing the cap. The cap comprises a lower body having a flat inner bottom surface with a passage in it, and a spring-loaded closing plate that likewise includes an opening. The closing plate is slidably movable over the flat inner bottom surface o the lower body against the force of the spring by means of a handle such that its opening is alignable with the opening in the bottom surface of the lower body to form an oil receiving passage.
