FLUID REGULATING DEVICE WITH BIASED CONTROL ELEMENT

摘要

A fluid regulating device includes an actuator housing (116), a control assembly (122), and a biasing member (192). The actuator housing defines a control cavity (118) and an actuator mouth (120). The control assembly is mounted within the control cavity and includes a piston (132), a stem (178), a lever (180) coupled between the piston and the stem, and a control element (127) mounted to the stem opposite the lever. The stem is disposed through the actuator mouth such that the control element is disposed outside of the control cavity. The stem is adapted for sliding displacement relative to the actuator mouth in response to sliding displacement of the piston. The biasing member is supported at least partly within the actuator mouth and biases the control element and the stem toward the control cavity.
