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.
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.

A gas spring assembly according to claim 1, wherein said second end member includes a wall that at least partially defines an end member chamber, and at least a portion of said first volume-displacing body is disposed within said end member chamber. 5. A gas spring assembly according to claim 4, wherein said wall of said second end member is an outer side wall extending longitudinally along said second end member, and said second end member includes a bottom wall disposed transverse to said longitudinal axis with said outer side wall and said bottom wall at least partially defining said end member chamber, and said first volume-displacing body disposed in abutting engagement with at least one of said outer side wall and said bottom wall. 6. A gas spring assembly according to claim 1, wherein said volume-displacing body is at least partially formed from a closed-cell polymeric foam material. 7. A gas spring assembly according to claim 1, wherein said volume-displacing body is at least partially formed from an open-cell polymeric foam material. 8. A gas spring assembly according to claim 7, wherein said volume-displacing body includes a coating extending along at least a portion of said open-cell polymeric foam material of said volume-displacing body. 9. A gas spring assembly according to claim 8, wherein said coating is formed from a polymeric material that is different from said open cell polymeric foam material and provides at least one of structure to said volume-displacing body, reduced permeability of pressured gas, and protection along at least one surface of said volume-displacing body. 10. A gas spring assembly according to claim 1, wherein said support wall is one of permanently affixed to said second end member, removably secured to said second end member and at least partially formed from a degradable material. 11. A gas spring assembly according to claim 1, wherein said flexible wall is one of a convoluted-style including one or more convolutions disposed between said first and second end members and a rolling lobe-style that forms a rolling lobe along said second end member. 12. A gas spring assembly displaceable between an extended condition and a compressed condition, said gas spring assembly comprising: a first end member;a second end member spaced from said first end member such that a longitudinal axis extends therebetween with one of said first and second end members including an opening extending therethrough and having a cross-sectional dimension;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 first end member that at least partially defines a cavity; and,a volume-displacing body disposed within said spring chamber and secured to one of said first end member and said flexible wall such that said body remains in spaced relation to at least said second end member in said 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 such that said volume-displacing body is at least partially disposed within said cavity, and 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. 13. A gas spring assembly according to claim 12, wherein said support wall is one of permanently affixed to said first end member, removably secured to said first end member and at least partially formed from a degradable material. 14. A gas spring assembly according to claim 12, wherein said flexible wall is one of a convoluted-style including one or more convolutions disposed between said first and second end members and a rolling lobe-style that forms a rolling lobe along one of said first and second end members. 15. A gas spring assembly according to claim 12, wherein said volume-displacing body is at least partially formed from a closed-cell polymeric foam material. 16.
