Abstract
A compressor system includes a fluid system having a cooler and a valve. The valve includes a housing and a spool disposed within the housing. The spool has a temperature sensitive wax cartridge, and is movable between an actuated position and a non-actuated position. When the spool is in the actuated position, inlet fluid flow enters the valve through an inlet port, exits the valve through the cooler port, flows through the cooler, reenters the valve through the cooler return, flows over the wax cartridge, and exits the valve through the outlet port. When the spool is in the non-actuated position, the inlet fluid flow bypasses the cooler, flows through the valve and over the wax cartridge, and exits the valve through the outlet port. The wax cartridge only senses the temperature of the inlet fluid flow when the spool is in the non-actuated position.
