1. A micro-valve assembly comprising:
a first housing divided into a high pressure supply chamber and a low pressure supply chamber, the high pressure supply chamber coupled to a high pressure port and the low pressure supply chamber coupled to a low pressure port; a second housing coupled to the first housing, the second housing defining a primary pressure chamber, the primary pressure chamber coupled to an outlet port configured to provide a pressure to a location outside of the micro-valve assembly; at least two micro-valve sub-assemblies, each of the micro-valve sub-assembly further comprising a sub-housing including a flange extending outwardly therefrom, a valve port extending through the sub-housing, and a MEMs micro-valve positioned in the valve port, the at least two micro-valve sub-assemblies being mounted by the flanges to one of the first and second housings wherein one of the sub-housings and flanges separates the primary chamber from the high pressure supply chamber and the other of the sub-housings and flanges separates the primary chamber from the low pressure chamber, and wherein one of the valve ports connects the high pressure supply chamber to the primary pressure chamber and the other of the valve ports connects the low pressure supply chamber to the primary pressure chamber; each of the MEMs micro-valves being actuatable between an open position and a closed position, the open position permitting fluid communication between the primary pressure chamber and high and low pressure supply chambers, the closed position prohibiting fluid communication between the primary pressure chamber and high and low pressure supply chambers; and a PC board positioned in the primary pressure chamber and having an air pressure sensor mounted thereon, the PC board being connected to terminals of each of the MEMs micro-valves by solderless connections to provide signals to the MEMs micro-valves causing actuation thereof |
