Patent number: 8061691Abstract: A piston adapted for use in offset mounting conditions includes a piston body having a longitudinally-extending axis. First and second securement features are located at radially outer positions relative to the axis. The first and second securement features are also located on one diametrical side of a midplane of the piston body. A plurality of support walls extends from the diametrically opposite side of the piston body toward the securement features. A gas spring assembly including such a piston is also included.Type: GrantFiled: February 5, 2008Date of Patent: November 22, 2011Assignee: BFS Diversified Products, LLCInventors: Daniel I Levy, Jonathan Hall

Patent number: 7530554Abstract: A fluid spring assembly includes a first end member and a second end member spaced from the first end member. A spring sleeve extends between the first and second end members. A third end member is disposed along the second end member and is axially displaceably secured thereto. The third end member engages the spring sleeve and is displaceable between a fully-assembled use condition and a fully-assembled adjustment condition in which the third end member and spring sleeve are disassociated with the second end member permitting approximately free rotation thereof. A method includes adjusting the rotational alignment of the fluid spring assembly.Type: GrantFiled: March 8, 2006Date of Patent: May 12, 2009Assignee: BFS Diversified Products, LLCInventor: Daniel I. Levy

Patent number: 7500659Abstract: A piston assembly for an air spring includes an outer shell and a structural insert. The outer shell includes a side wall and an end wall at least partially defining a shell cavity having an open end. The structural insert is received in the shell cavity and includes a central portion and a plurality of support walls extending outwardly from the central portion toward the side wall of the outer shell. The central portion includes first and second opposing ends with the first end disposed toward the end wall of the outer shell and the second end disposed toward the open end of the outer shell. An air spring assembly includes such a piston assembly. A method of manufacturing an air spring assembly is also included.Type: GrantFiled: April 6, 2006Date of Patent: March 10, 2009Assignee: BFS Diversified Products, LLCInventor: Daniel I. Levy

Patent number: 6386524Abstract: An air spring has a piston formed of a high strength plastic material consisting of a main shell and a bottom end sealing plate extending between a pair of concentric inner and outer annular walls. A pair of internal auxiliary reservoirs or subchambers are formed within the piston and are in fluid communication with each other and with the main air chamber formed by a flexible bellows extending between the piston and an end plate. A plurality of radially extending reinforcing ribs extend between the inner and outer annular walls of the shell and a rigid central post. A central planar support surface having an area approximately 20% than that of the piston base area provides a reduced surface area for mounting the piston on a smaller support surface.Type: GrantFiled: April 25, 2000Date of Patent: May 14, 2002Assignee: BFS Diversified Products, LLCInventors: Daniel I.
