Abstract: An actuator for a valve lift control device linearly moves a control shaft to change a valve lift in accordance with an axial position of the control shaft. A first and a second rotation cam integrally rotate around a common rotation axis by transmission of torque, so that a direct acting follower, which includes a first and a contact members, linearly moves with a control shaft. The first and a second rotation cams are respectively in contact with the first and the second contact members via a first and a second contact points. The first contact point is located on the opposite side of the second contact point with respect to the rotation axis. A sum of a first rotation cam lift of the first rotation cam and a second rotation cam lift of the second rotation cam is substantially constant in a predetermined rotation angular range of the first rotation cam and the second rotation cam.

Abstract: A device for internal combustion engines particularly automobile engines, which varies the opening duration and the lift of the timing valves. This variation results from the utilization of all or part of the profile of an alternating cam of which the motion about an axis is provided by rotating main cams which contact rollers carried on the alternating cam, and is transmitted to a roller in contact with the lever which then actuates the valve. The timing is varied by adjusting the position of the roller by means of support arms by which the roller is displaced with respect to the alternating cam and lever.

Abstract: A hybrid vehicle includes an internal combustion engine and a rotary electric machine. The internal combustion engine includes a variable valve actuating device configured to change an operation characteristic of an intake valve. The rotary electric machine is configured to generate driving force for propelling the hybrid vehicle. A controller for the hybrid vehicle includes a traveling control unit and a valve actuation control unit. The traveling control unit executes traveling control for causing the hybrid vehicle to travel by using the driving force of the rotary electric machine while stopping the internal combustion engine. The traveling control unit starts up the internal combustion engine while executing the traveling control. The valve actuation control unit controls the variable valve actuating device. The valve actuation control unit, when the internal combustion engine is started up while the traveling control is executed, sets at least one of a valve lift and valve operating angle of the intake valve such that the at least one of the valve lift and valve operating angle of the intake valve when the hybrid vehicle travels at a first vehicle speed is smaller than the corresponding at least one of the valve lift and valve operating angle of the intake valve when the hybrid vehicle travels at a second vehicle speed. The second vehicle speed is lower than the first vehicle speed.
