Patent ID: 6966336

Claim:
A microvalve that comprises: a first body having a first interior surface and two or more outlet ports at the first interior surface that are in fluid communication with two or more first channels that each defines a threaded conical-shaped cavity and wherein at least one of the first channels has a first ferrule secured thereto wherein each first ferrule is externally threaded and defines a bore extending therethrough with each first ferrule supporting a first fluid conduit wherein each first ferrule is threaded into the channel of the first body and wherein each first ferrule defines a lower tapered exterior end; a second body having a second interior surface and two or more inlet ports at the second interior surface that are in fluid communication with two or more second channels wherein the outlet ports of the first body are coaxial with the corresponding inlet ports of the second body such that there are at least two sets of coaxial port outlets and port inlets that each defines a threaded conical-shaped cavity and wherein at least one of the second channels has a second ferrule secured thereto wherein each second ferrule is externally threaded and defines a bore extending therethrough with each second ferrule supporting a second fluid conduit wherein each second ferrule is threaded into the channel of the second body and wherein each second ferrule defines a lower tapered exterior end; a plate member, which has a substantially planar first mating surface and a substantially planar second mating surface, that is slidably positioned between the first interior surface and the second interior surface wherein the plate member has at least one aperture that traverses the height of the plate member, and wherein the aperture can be positioned to be coaxial with any of the at least two sets of coaxial port outlets and port inlets; and means for securing the first surface of the first body against the first mating surface and for securing the second surface of the second body against the second mating surface that enables the microvalve to operate at a pressure of at least 500 psi without fluid leakage.
