FUEL SYSTEM INCLUDING AN APPARATUS AND A METHOD FOR FUEL VAPOR PRESSURE MANAGEMENT |
摘要 |
<p>An apparatus and method of operating a fuel vapor pressure management apparatus that includes a housing and a pressure operable device. The housing defines an interior chamber and includes first and second ports that communicate with the interior chamber. The pressure operable device separates the interior chamber into a first portion in fluid communication with the first port and a second portion in fluid communication with a second port. The pressure operable device includes a poppet movable along an axis and a seal adapted to cooperatively engage the poppet. A first arrangement of the pressure operable device occurs when there is a first negative pressure level at the first port relative to the second port, and the seal is in a first deformed configuration. A second arrangement of the pressure operable device permits a first fluid flow from the second port to the first port when the seal is in a second deformed configuration. And a third arrangement of the pressure operable device permits a second fluid flow from the first port to the second port when the seal is in an undeformed configuration.</p> |
