Title:
LOST MOTION VALVE CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/015603
Kind Code:
A3
Abstract:
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.
