ABSTRACT:
A solenoid valve includes a flexible diaphragm and ball to control hydraulic or pneumatic fluid flow. The diaphragm provides an essential part of a complete seal which prevents contaminants from adversely affecting operation of the valve. The diaphragm and ball are formed into a single impervious integral structure. The valve additionally includes a series of radially arranged flutes which surround the armature to allow movement of entrapped fluids within the valve so as to enable more rapid actuation of the valve, and also a conical end structure within the armature for similar improvement.
