Abstract

A push to release fuel filler door assembly for a motor vehicle includes a door on the exterior of the vehicle having a latch that cooperates with a spring biased plunger which rotates and translates axially. The plunger includes radially extending pins which are received in complementary helical tracks on the inner surface of an inner housing. The tracks define a closed path having a first segment, in which the pins travel while the fuel door is being closed, a second segment in which they travel while the fuel door is opening and a latching recess between the first and second segments in which the pins reside when the door is closed. The inner housing typically includes three segments or sections and is, in turn, received and retained within an outer housing which mounts on a fuel door inlet assembly.
