Titre
(EN) Turbocharger having pneumatic actuator with pilot valve
(ZH) 具有带导引阀的气动致动器的涡轮增压器
Abrégé
(EN)
A pneumatic actuator for controlling the wastegate valve of an exhaust gas driven turbocharger includes a pilot piston which is responsive to boost pressure to open only when a desired boost pressure is attained. Accordingly, premature opening of the wastegate valve is avoided because the main actuator piston is maintained at atmospheric pressure until the desired actuating pressure is attained.

(ZH)

一种气动致动器,用来控制一种以废气驱动的涡轮增压器的废气闸阀。它包含一个导引活塞,该活塞只在达到所要求的增压压力时才响应增压压力而打开。依此,避免了废气闸阀的过早打开,这是因为主致动活塞一直保持在大气压力下,直到获得所要求的致动压力。
