ABSTRACT:
An air damper assembly for controlling the dampening rate of an openable object includes a piston head having a molded channel therein and a lip seal member disposed around the connecting member of the piston head to form a continuous seal therebetween. The piston head is formed of a pair of axially spaced-apart first and second circular plate members which are connected by the connecting member. The second circular plate member is formed of a diameter which is smaller than the diameter of the first circular plate member so as to allow the outer peripheral portion of the lip seal member to collapse and become disengaged from the inner peripheral sidewall of the housing member.
