Something about caps fuel parts
This invention relates to caps fuel parts and more particularly to fuel caps of the type that are adapted to be moved into and out of a closing position within a fuel tank filler neck by oppositely directed torque movements.
In recent years, the most popular type of fuel cap utilized is the so-called threaded or multiple turn gas gap. An early version of this type cap is disclosed in U.S. Pat. No. 4,091,955. A typical threaded fuel cap includes an outer handle component, an inner closure component and a torque override connection between the handle and closure. The inner closure component is made up of a tubular body having suitable valving mounted interiorly thereof. The lower exterior of the portion of the body is threaded to engage within cooperating threads formed in the upper end of the fuel neck.
