Abstract
An electromagnetic flow control valve assembly includes a valve body having first and second ports and a valve member for controlling fluid communication between said first and second ports. An annular diaphragm is connected at its inner periphery to the valve member and at its outer periphery to the valve body so as to define with said valve body first and second chambers. The first chamber is in continuous fluid communication with the first port through a passage in the valve member while the second chamber is in continuous communication with the second port. The area of the diaphragm subjected to fluid pressure within the second chamber being equal to the effective area of the valve member subjected to fluid pressure within the second chamber to thereby offset the force of fluid pressure acting on the valve member.
