Volume booster with stabilized trim

摘要

A fluid flow control device includes a body (44) having an inlet connection (30), an outlet connection (32), and a discharge port (36). A supply path extends between the inlet connection and the outlet connection and a booster module (45) is disposed within the body. The booster module includes a control element and an actuator element and defines an exhaust path extending between the outlet connection and the discharge port. A supply port is disposed within the booster module along the supply path between the inlet connection and the outlet connection and at least a first damping means operatively connected to the booster module.
