Abstract:
A capless refueling assembly for selectively opening and closing a filler neck of a fuel tank, said assembly comprising:a housing for attachment to the filler neck;an outer filler door pivotally mounted between open and closed positions for facilitating access to said filler neck;a lid structure movably mounted to said housing between open and closed positions for facilitating the opening and closing of the filler neck;a valve mechanism movably mounted to said housing between seated and unseated positions for selectively releasing pressurized fluid from the filler neck;an actuation device operably connected between said outer filler door and said valve mechanism said actuation device including a cam member rotatably mounted to said housing and threadably engaging said valve mechanism; said cam member coupled to said outer filler door to transfer movement thereof into rotation of said cam member effecting said movement of said valve mechanism, whereby as said outer filler door moves from the closed position to the open position, said valve mechanism automatically moves from said seated position to said unseated position while said lid structure remains in said closed position, thereby venting the pressurized fluid from the filler neck before said lid structure is moved to said open position.
