A system that facilitates managing resources based at least in part upon an established context. The systems and techniques are described in the context of an electric powered vehicle. A combination deflector pop-up pressure regulating mechanism housed in the filter of the nozzle housing assembly is also shown. The shaft defines a pin hole, and the shaft is engaged in the housing. The back wall and the form edges of the front walls, proceeding from the foil supply edge and a section that converges in continuous direction between the front walls, are developed relative to one another and continually approaching until the end of the downwardly open slit.
