发明名称 ASYMMETRIC VOLUME BOOSTER ARRANGEMENT FOR VALVE ACTUATORS.
摘要 <p>An asymmetric volume booster assembly includes a differential actuator (24) movable in a first direction and a second direction, a first booster (44) in fluid communication with the actuator, and a second booster (48) in fluid communication with the actuator. The first booster includes a first supply passage (60) and a first exhaust passage, wherein the first supply passage supplies fluid to the actuator and the first exhaust passage exhausts fluid from the actuator. The first exhaust passage is configured to produce a first fluid flow resistance. The second booster includes a second supply passage (58) and a second exhaust passage, wherein the second supply passage supplies fluid to the actuator and the second exhaust passage exhausts fluid from the actuator. The second exhaust passage is configured to produce a second resistance to fluid flow. The first fluid flow resistance is greater than the second fluid flow resistance, such that the actuator moves substantially symmetrically in the first direction and the second direction.</p>
