Microvalve

摘要

A microvalve assembly (10) includes an elongate valve body (14) having opposed first and second major surfaces, the first major surface defining a valve recess (34) and the second major surface defining first and second fluid ports (20,22). Both the fluid input port and the fluid output port extend in fluid communication with the valve recess. A gasket (12) is freely positioned within the valve recess so as to extend in overlying registry with either or both of fluid ports. A valve cover (16) is bonded to the valve body and includes a first planar surface positioned in overlying registry with the valve recess so as to enclose the gasket therein. The valve cover is deflectable into the valve recess so as to cause the gasket to seal at least one of the fluid ports.
