Modifications for pneumatic pogo sticks

A pogo stick, comprising:

• a housing enclosing a volume of compressible working fluid;
• a first chamber, having a first chamber volume, bounded at least partially by a piston and configured to at least partially enclose the volume of compressible working fluid;
• a second chamber, having a second chamber volume, at least partially enclosing the volume of compressible working fluid, the second chamber volume being fixed;
• the piston, configured to transition between at least a first position corresponding to a first chamber volume maximum and a second position corresponding to a first chamber volume minimum, at least a portion of the working fluid passing from the first chamber to the second chamber through a fluid connection as the piston transitions from the first position to the second position;
• and
• a sliding shaft connected to the piston;
• wherein the first chamber volume maximum and the first chamber volume minimum define a first chamber compression ratio;
• wherein the first position of the piston corresponds to a total working fluid volume maximum and the second position of the piston corresponds to a total working fluid volume minimum, the total working fluid volume maximum including the first chamber volume maximum and the second chamber volume, the total working fluid volume minimum including the first chamber volume minimum and the second chamber volume;
• and
• wherein the total working fluid volume maximum and the total working fluid volume minimum define a total compression ratio for the working fluid, the total compression ratio being less than the first chamber compression ratio.
