ABSTRACT:
A valve (10) is provided for the control of fluid flow. The valve (10) includes a housing (20) having a fluid inlet aperture (40) and a fluid outlet aperture (48). A piezoelectric device (12) is disposed within the housing (20) adjacent the fluid inlet aperture (40) and the fluid outlet aperture (48). Structure (52, 54) is provided for applying a voltage to the piezoelectric device (12) for causing motion of the piezoelectric device (12) to thereby establish a path (62) within the housing (20) between the fluid inlet aperture (40) and the fluid outlet aperture (48) to enable fluid to flow through the housing (20).
