    • There is described a valve control device (113) for use in an internal combustion engine, the engine comprising an engine valve (101) and a camshaft having a cam profile (117) comprising a first lift profile. The valve control device comprises a first body (201) and a second body (203). The device is configurable in a first configuration and a second configuration. When the device is in the first configuration relative movement between said first body and second body caused when the first lift profile engages a cam engagement surface inhibits a valve actuating linkage from actuating the engine valve. The device further comprises means which when the device is in the second configuration prevents relative movement between said first and second bodies when the first lift profile engages the cam engagement surface to enable the valve actuating linkage to actuate the engine valve. When the device is in the second configuration, said means is arranged such that substantially all of the force exerted thereon as the valve is actuated is compressive.
    • 描述了用于内燃机的阀控制装置(113),该发动机包括发动机阀(101)和具有包括第一升程廓线的凸轮廓线(117)的凸轮轴。 阀控制装置包括第一主体(201)和第二主体(203)。 该设备可配置为第一配置和第二配置。 当所述装置处于所述第一本体与所述第二本体之间的第一配置相对运动时,所述第一本体与所述第二本体在所述第一升程曲线接合凸轮接合表面时产生,从而阻止阀致动连杆机构致动所述发动机气门。 所述装置还包括当所述装置处于所述第二构型时防止所述第一和第二本体之间的相对运动,当所述第一升程轮廓接合所述凸轮接合表面以使所述阀致动联动装置致动所述发动机气门时。 当装置处于第二构造时,所述装置被布置成使得当致动阀时作用在其上的基本上所有的力都是压缩的。
