ABSTRACT:
A fluid control valve for a fluid system, such as an air conditioning system, in which a flow passage is defined by a radially flexible tubular member so that the flow area of the valve therethrough is variable. The tubular member and an encircling magnetic field producing means define an annular space therebetween containing a plurality of small iron particles which are attracted to an intermediate portion of the annular space when a magnetic field is produced, thereby causing inward movement of the flexible tubular member to decrease the valve's flow area.
