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 valves are opened when disc rotates.

Abstract: A device for internal combustion engines, particularly car engines, allows to vary the opening duration and the lift of the timing valves. The variation results from the utilization of all or part of the profile of the alternating cam (9) of which the motion about the axis (14) is provided by the rotating leading cams (10, 11) by contact of the rollers (12) and is transmitted to the roller (8) which acutates with its shaft (13) the rocker arm (3) of the valve (6) returned by the spring (7). The adjustment is carried out by positioning the sprocket wheel (8) by means of the support arms (15) of the shaft (13) which are keyed to the control shaft (14) by means of pins (16).

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.
