QUICK RESPONSE FLOAT-OPERATED VAPOR VENT VALVE |
| 摘要 |
A valve assembly is provided for venting pressure in a fuel tank. The valve assembly includes a housing that defines a passage and a valve seat provided at one end of the passage. A float assembly is disposed within the housing. The float assembly includes a flexible membrane seal that seals against the valve seat when the float assembly rises in response to a rising fuel level in the fuel tank, and a reopen profile that applies a reopening force along a select portion of the membrane seal to release the membrane seal from the valve seat when the float assembly drops in response to a falling fuel level in the fuel tank. |
