Abstract
A micro-valve assembly for incorporation into a vehicle seat having an inflatable bladder. The micro-valve assembly includes a first housing that cooperates with two micro-valve sub-assemblies to define a high and low pressure supply chamber. A second housing cooperates with both of the first and second micro-valve subassemblies to define a primary pressure chamber. Each of the micro-valve sub-assemblies further includes a valve port extending therethrough with a MEMS micro-valve positioned in the valve port. The MEMS micro valves are actuatable between open and closed positions to respectively permit and prohibit fluid communication between the primary pressure chamber and high and low pressure supply chambers.
