Abstract: A valve arrangement for a cylinder deactivation engine is provided to simplify structure of the valve arrangement through allowing a valve arrangement for opening and closing intake and exhaust valves to be formed with only single type of cam. A valve arrangement for a cylinder deactivation engine comprises a rotational body(10) extending in a forth and rear direction at both ends of a central body(12), a fixed body(20), a locking device(30), and a follower(40). The fixed body includes a path connection body portion(22) receiving hydraulic power from a lash regulator, an upper body portion(24) extending over the central body form the path connection body portion, a lower body portion(26) hinged to a first axis(X1), and a return spring(28) to resiliently support the upper body portion. The locking device includes a locking pin(32), which restricts and releases the pivoting movement of the central body of the rotational body.

Abstract: A variable valve lift apparatus of an engine for vehicles is provided to freely control a valve lift by controlling the position of a roller except for a pivot point of an HLA(Hydraulic Lash Adjuster) side and a valve stem end contact unit. A variable valve lift apparatus of an engine for vehicles is used in a valve train. The valve train is provided with a valve(4) with a valve spring(2), a roller finger follower(8) with a roller(6) for operating the variable valve lift, an HLA(10) forming a pivot point of the roller finger follower, and a cam(12) with one cam profile. The roller is placed at a slide hole(18) formed at both sidewalls of a roller installation unit of the roller finger follower to be movable back and forth by installing a roller supporting shaft(20). The roller supporting shaft is connected to a hydraulic transferring unit which moves the roller back and forth by oil pressure supplied from the HLA.
