Abstract:
A valve diaphragm processed by cold working a small concentric region of one surface has a permanent axisymmetric deformation. The deformed diaphragm can be used in a manner which causes continual elastic compression loading of the diaphragm material. The loading of the deformed diaphragm provides a valve restoring spring force and simultaneously defeats diaphragm tendency toward exhibiting hysteresis. The restoring force provided by the diaphragm can also lessen actuator hysteresis.

Claim (Index 10):
A control valve comprising:\n a valve body having a fluid inlet conduit terminating at a fluid inlet orifice and a fluid outlet conduit commencing at a fluid outlet orifice; a seat defined at one of the fluid inlet orifice and the fluid outlet orifice; a valve housing body secured to the valve body; a valve diaphragm in sealing engagement with the valve housing body at an outer periphery of the valve diaphragm, the valve diaphragm having a first surface and a second surface opposing the first surface, one of the first surface and the second surface having a plastically deformed concentric strain hardened region having a concave shape; and a control element attached to the valve diaphragm, the control element having a control surface offset from the first surface of the valve diaphragm, the control surface being configured to selectively engage the seat, the valve body, the valve housing body, and the valve diaphragm cooperating to define a valve chamber; wherein the plastically deformed concentric strain hardened region biases the control surface of the control element one of toward and away from sealing engagement with the seat.
