Abstract: A shock absorbing device may include a housing, a piston, and membrane. The housing may define space. The piston may move within the space to adjust a pressure of a gas in a main spring chamber to form a gas spring. The piston and the housing may partially define the main spring chamber within the space. The membrane may be positioned in the space. The housing and the membrane may define a secondary spring chamber within the space. The membrane may partially define the main spring chamber and may be sufficiently elastic such that when the piston adjusts the pressure of the gas in the main spring chamber, a force applied on the membrane by the gas in the main spring chamber changes and causes the membrane to selectively deform to adjust a pressure of gas in the secondary spring chamber to control a spring rate of the gas spring.
