ABSTRACT:
A temperature compensator mounted on a gas pressure regulator having a spring loaded valve in which the amount of compression in the spring is changed by moving an adjusting member of the compensator in response to changes in temperature. The temperature compensator may include a piston and cylinder assembly containing a fluid which contracts in response to a reduction in temperature and expands in response to an increase in temperature. The piston is in engagement with the spring and is moved to change the amount of compression in the spring in response to the change in temperature.
