A mass fluid flow controller has a valve which is controlled by a controller rod structure which is substantially pivotally mounted on a metallic diaphragm which stretches and unstretches with the movement of the rod structure. In the relationship between the controller rod structure and a ball which acts as a gate-member for the valve, an elongated stem rod having a sleeve about it may be used in fixing the ball to the controller rod structure. The stem rod may be mounted by fixing it to the elongated sleeve, a distance from the gate-member side of the controller rod structure that is substantially greater than the distance of the position of the ball from the gate-member side of the controller rod structure.

[ What is claimed is:] [1.] A fluid flow controller having a sensor to measure fluid flow and an actuator to respond to the sensor, comprising:input pipe structure defining an inlet for receiving a fluid having a flow and defining a fluid flow opening through said structure;intermediate pipe structure for receiving said fluid downstream from said input pipe structure and defining a fluid flow opening through said intermediate pipe structure;output pipe structure for receiving said fluid downstream from said intermediate pipe structure and defining a fluid flow opening through said output pipe structure;a valve seat mounted in said intermediate pipe structure;a valve gate-member associated with said valve seat;a gate-member controller including,a controller rod structure having a gate-member control portion associated with said gate-member to control the gate member, an actuation portion associated with said actuator for control by said actuator, and a mounting portion between said gate-member control portion and said actuation portion,a mounting structure for said controller rod structure, said controller rod structure substantially pivotally connected to said mounting structure along said controller rod structure mounting portion, said actuation and gate-member control portions of said controller rod structure movable in opposing directions with reference to the position of said mounting structure in response to said actuator to adjust said fluid flow, and said control portion defining, from said control portion, a gate-member direction, with reference to said substantially pivotal movement, toward said gate-member, and an opposite direction, with reference to said substantially pivotal movement, away from said gate-member, andan elongated stem rod, connected to said gate-member and to said control portion of said controller rod structure, and mounted at a connection located in said opposite direction from said control portion.
