Abstract
A cap assembly for covering an injector of a lubricant metering device to sealingly protect the injector from moisture and dirt. The injector has a generally cylindric body and an end structure narrower than the body projecting endwise from the body. The assembly has a cap including a generally cylindric tube having a side wall, an open end, a closed end and a configuration such that the cap is shaped and sized for detachable mounting on the body of the injector in a covering position in which the tube encloses the end structure of the injector. A flexibly resilient gasket has an annular shape with an inner edge sized for surrounding the end structure to enable the gasket to be sealingly secured to the structure and an outer edge sized for engaging an inner surface of the side wall of the cap and forming a fluid-tight seal thereon when the cap is mounted in its covering position. The gasket holds the cap in generally fixed position relative to the injector and further prevents passage of moisture or dirt therepast. The gasket has at least one notch in the outer edge for permitting passage of air through the notch to prevent build-up of air pressure in the cap as the cap is mounted on the injector.
