Abstract:
A suspension system, comprising:a first tubular element in telescoping, slidable engagement with a piston rod, said first tubular element having first and second ends, said second end of said first tubular element being closed;said piston rod extending into said first tubular element and having a first end and a second end;a compressor piston positioned on said first end of said piston rod for slidable engagement with said first tubular element;a first biasing element positioned between said compressor piston and said closed second end of said first tubular element and biasing said compressor piston toward said first end of said first tubular element;a second biasing element positioned between said first end of said first tubular element and said compressor piston and biasing said compressor piston toward said second end of said first tubular element;whereinsaid compressor piston is in sealing engagement with said first tubular element and isolates a first portion of said first tubular element in which said first biasing element is positioned from a second portion of said first tubular element in which said second biasing element is positioned;said second end of said first tubular element is closed by a seal; andsaid first biasing element comprises a gas spring formed in a substantially air-tight chamber defined by said first tubular element, said compressor piston, and said seal.
