Summary:Methods and systems are provided for deactivating a valve actuation mechanism. In one example, a system may include first and second hydraulic galleries for supplying hydraulic fluid to a switchable roller finger follower, and a third hydraulic gallery for promoting the flow of air away from the first hydraulic gallery. The third hydraulic gallery may receive a restricted flow of oil from a hydraulic restrictor incorporated into an annular clearance between a VCT oil control valve and a mating bore within the cylinder head. 本发明提供用于停用阀门致动机构的方法和系统。在个示例中，系统可包括用于供应液压液体到可切换滚柱指状从动件的第液压通路和第二液压通路，以及用于促进气流远离第液压通路的第三液压通路。第三液压通路可接收来自液压限制器的受限油流，液压限制器被结合到VCT控油阀和汽缸盖内的匹配镗孔之间的环形空隙内。
