Abstract
The fuel vapor absorber includes, on a housing member and separately from an air inlet, an orifice for the circulation of fuel vapors coming from a tank. A pipe for supplying these vapors passes through the housing member via the orifice and forms a support for a pressure regulating valve, provided with a valve body and a closure member. The pipe, provided for adaptation between the valve and the housing, is fastened to the housing member, forming at least one annular sealing area surrounding the pipe. The valve, which is fastened by snap-fitting or the like, may be housed in the inside volume of the absorber, where an absorption product is stored. The pipe is typically mounted on the inner face side of the housing member and may be directly welded.
