초록 ▼

An evaporative emission control system for an automotive vehicle comprises an integrated roll-over valve and vapor pressure sensor assembly mounted by means of a grommet in the top wall of the vehicle\s fuel tank. The vapor pressure sensor forms part of an on-board diagnostic system for testing the

대표청구항 ▼

An automotive vehicle canister purge system comprising a vapor collection canister, a passage for communicating said vapor collection canister to headspace of a tank for holding a volatile fuel used to operate an internal combustion engine that powers such a vehicle, said passage comprising a roll-over valve that is open under a first set of conditions that allow tank/canister communication, those conditions comprising one or both of such tank being upright within a certain range of tilt from vertical and the level of liquid fuel in such tank being below a certain level, and that is closed under a second set of conditions that disallow tank/canister communication and thereby prevent any appreciable amount of liquid fuel from passing to said canister in the event that such a vehicle encounters an occurrence such as a roll-over, the latter conditions comprising one or both of such tank being tilted beyond said certain range of tilt and the level of liquid fuel in such tank rising to said certain level, said system further comprising means for purging said canister of collected fuel vapors to an intake manifold of such an engine in accordance with conditions of engine operation that are conducive to purging, said system further comprising a diagnostic means for subjecting both such headspace and a portion of said system that is in communication with such headspace, to leak testing, said diagnostic means comprising a vapor pressure sensor for sensing vapor pressure within such headspace, characterized in that said vapor pressure sensor is mounted on said roll-over valve and comprises a sensing port that is placed in communication with such headspace by a passageway that extends through a body portion of said roll-over valve, and sealing means sealing said vapor pressure sensor\s sensing port to said passageway in a fluid-tight manner so that fluid communicated from such tank to said sensing port is sealed against leaking via said vapor pressure sensor\s mounting on said body portion of said roll-over valve.
