    • A valve control system for an internal combustion engine including a poppet valve (21) and high lift (15) and low lilt (31) cam lobes. A latchable rocker arm includes an outer rocker arm (33) and an inner rocker arm (35), and a slider mechanism (37) which is biased by a spring (67) to the high lilt mode (FIG. 1). An actuator assembly (27) includes and arm (103) biased by a spring (101) into engagement with the slider (37), biasing the slider toward the unlatched (low lift) mode (FIG. 2 ). The actuator (27) includes an electromagnetic coil (83) which moves an armature (87) into engagement with the arm (103), biasing the arm in opposition to the force of the actuator spring (101), but aided initially by the force of the slider spring (67).
    • 一种用于内燃机的阀控制系统,其包括提升阀(21)和高升程(15)和低叶片(31)凸轮凸角。 可锁定的摇臂包括外摇臂(33)和内摇臂(35),以及由弹簧(67)偏压到高速模式(图1)的滑块机构。 致动器组件(27)包括通过弹簧(101)偏置成与滑块(37)接合的臂(103),将滑块朝向解锁(低提升)模式(图2)偏置。 致动器(27)包括电磁线圈(83),其使衔铁(87)与臂(103)接合,使臂相对于致动器弹簧(101)的力偏置,但最初由力 的滑块弹簧(67)。
