ABSTRACT:
An engine poppet valve operating mechanism comprises a pivotal link which is positioned in use to engage the stem of the valve to be operated. An electro magnetic device has a winding which electric current can be supplied when it is required to open the valve. An output member forms part of the device and interposed between the output member and the link is energy storing means. The arrangement is such that when the device is energized the output member will move to an extended position and the movement of the link and valve will be at least partly effected by energy stored in the means during movement of the output member to the extended position.
