    摘要: A hydraulic fluid de-aeration device for a hydraulically actuated variable valve actuation system is provided. The device includes a bridge and a de-aeration chamber having an upper chamber, a lower chamber, and a central axis. A vent pipe is arranged along the central axis of the de-aeration chamber and can include at least one vent hole. The bridge is arranged such that hydraulic fluid flowing from the bridge is directed towards an outer wall of a top portion of the lower chamber. The device includes a cover that integrates the upper chamber with a vent hole for air that is expelled from the hydraulic fluid. An optional gasket or plate configured with at least one vent hole can be arranged between the upper and lower chamber. The vent pipe can be arranged within the cover and extend through the upper chamber to the lower chamber.
