ABSTRACT:
A fluid valve apparatus having a stationary semicylindrical member through which a fluid port extends is characterized by a valve band which is flexibly movable from a first, closed, to a second, open, position in response to an actuating force. In the closed position, the flexible valve band is pulled taut about the surface of the cylindrical member and covers the fluid port. When closed, the valve band is subjected to a compressive force on the first surface thereof adjacent to the stationary cylindrical member and a tensile force on a second surface thereof. While in the open position, in which the fluid port is uncovered, the flexible valve band is subjected only to a tensile force tangentially directed relative to the surface of the cylindrical member. A rocker actuating member is operably connected to the flexible valve band and transmits an actuating force thereto by pivoting about a pivot point instantaneously defined by the intersection of the tangential direction of the tensile force on the flexible valve band and a second direction tangentially disposed relative to the surface of the cylindrical member.
