    Abstract: An apparatus for operating the valves on internal combustion engines with a variable valve lift curve has a multimember, rotary gear, which comprises the valve-guiding case, a rotary cam connected to the case via a pivot joint and whose drive is derived from the crankshaft, an intermediate member operated by the cam by a curve joint and a driven member, which is supported by a joint on the case and operatively connected to the intermediate member via a joint and which transfers the movement to the valve. The intermediate member is supported by a curve joint on the case, with the curve of the curve joint, located on the intermediate member, having a portion forming a locking device and also a control portion. The position of the curve supported on the case and associated with this curve joint or the position of the pivot joint of the cam is adjustable during operation.

    Abstract: A torsion assembly for providing controllable torsion to a camshaft, including: a spring assembly including a first spring; and, a contact element arranged to engage at least one lobe for the camshaft. For a locked mode: the contact element is arranged to be displaced by the at least one cam lobe; the contact element is arranged to compress the first spring; and the first spring is arranged to impart a first torque to the camshaft via the contact element. For an unlocked mode, the contact element is arranged to be displaced by the at least one cam lobe and the contact element is arranged to impart a second torque, less than the first torque, to the cam shaft via the contact element.

    Abstract: A variable valve actuation mechanism includes a control shaft and a rocker arm. A second end of the rocker arm is connected to the control shaft. The rocker arm carries a roller for engaging a cam lobe of an engine camshaft. A link arm is pivotally coupled at a first end thereof to the first end of the rocker arm. An output cam is pivotally coupled to the second end of the link arm, and engages a corresponding cam follower of the engine. A spring biases the roller into contact with the cam lobe and biases the output cam toward a starting angular orientation.

    Abstract: The present invention is for the kind of power machines, engines or compressors which have two or more pistons which work against each other preferably with a common combustion or compression chamber in a stationary cylinder and where the power is transmitted to a rotating movement without an intermediate crankshaft. It is an object of the present invention to obtain such power machine having a simple valve control means. One such device has two parallel plane discs, one stationary disc (8) and one relatively thereto rotating disc (13). The stationary disc (8) is mounted to a housing (9) and the disc (8) in turn has one in its centre positioned cylinder (1) with two end walls (2, 3). In the cylinder there are two pistons (4, 5) which are working pistons of a combustion engine and have a common combustion chamber. At the centre of the cylinder bore adjacent to the upper dead centres, UDC, of the pistons and at opposite sides thereof there are two valves (50, 51). The valve shafts at the ends which are turned only from the cylinder contact a controlling curve or surface (56) which is a part of the rotating disc. On the control curve there are raised parts (57, 58) at which the valve are opened when disc rotates.
