VOLUME BOOSTER WITH REDUCED NOISE TRIM

摘要

A fluid flow control device having a body (44) having a inlet connection (30), an outlet connection (32), a discharge port (36) and a booster module (45) disposed within the body. The booster module including a control element (48) and an actuator element having a noise - reducing trim element with a supply path extending between the inlet connection and the outlet connection and an exhaust path extending between the outlet connection and the discharge port. The noise - reducing trim element being coupled immediately adjacent to the discharge port such that the noise - reducing trim element distributes a fluid flow to the discharge port via the exhaust path into a plurality of fluid jets to substantially inhibit jet recombination at the discharge port.
