Method and system for regulating hydraulic pressure in heavy equipment

A method of operating a hydraulic system to regulate fluid pressure of heavy equipment including:

• determining changes of pressure based on temperature changes;
• expanding a thermal polymer when temperature in the system increases;
• contracting the thermal polymer when the temperature in the system decreases;
• and
• metering fluid flow based on the expanding and contracting of the thermal polymer.

An apparatus for regulating fluid pressure of heavy equipment, comprising:

• a means for determining changes of pressure based on temperature derivatives;
• a means for expanding a thermal polymer when temperature increases;
• a means for contracting the thermal polymer when the temperature decreases;
• and
• a means for metering fluid flow based on the expanding and contracting of the thermal polymer.

An apparatus for regulating fluid pressure in a hydraulic system, comprising:

• a main body;
• a thermal element coupled to the main body, the thermal element being configured to be mechanically responsive to temperature changes;
• and
• an orifice spool mechanically coupled to the thermal element, the orifice spool being configured to conduct hydraulic fluid,
• wherein the thermal element is configured to reposition the orifice spool in response to a temperature change.
