Gas spring assembly and method of adjustment

摘要

A gas spring assembly that is displaceable between an extended condition and a compressed condition can include a first end member, a second end member, a flexible wall secured between the first and second end members, a spring chamber and a volume-displacing body disposed within the spring chamber. The body can be supported along one of the flexible wall and the first end member such that the body remains in spaced relation to at least the second end member in a compressed condition of the gas spring assembly. A method of adjusting a gas spring assembly is also included.

主权项

1. A gas spring assembly displaceable between an extended condition and a compressed condition, said gas spring assembly comprising:
a first end member including an opening extending therethrough with said opening having a cross-sectional dimension; a second end member spaced from said first end member such that a longitudinal axis extends therebetween; a flexible wall secured between said first and second end members and at least partially defining a spring chamber; a support wall secured along said second end member and at least partially defining a cavity; and, a volume-displacing body disposed within said spring chamber and at least partially within said cavity such that said volume-displacing body is secured to said second end member and such that said volume-displacing body remains in spaced relation to said first end member in a compressed condition of said gas spring assembly, said volume-displacing body being at least partially formed from a flowable polymeric material introduced into said spring chamber through said opening in said first end member such that in a cured condition said volume-displacing body has a cross-sectional dimension that is greater than said cross-sectional dimension of said opening.
