Abstract: A valve mechanism for a port of an internal combustion engine is described which comprises a) a poppet valve (16) reciprocable with constant stroke relative to a valve seat (14) in the engine cylinder head (10) under the action of a valve drive train, b) a valve guide (30) interposed between the poppet valve (16) and the engine cylinder head (10) and reciprocably driven, through a spring (42), by the drive train of the poppet valve (16) in a direction to follow the movements of the poppet valve (16), and c) an adjustable stop (36) for limiting the stroke of the valve guide (30) relative to the valve seat (14) such that the guide (30) may be stopped at a variable point in its stroke, the end of the valve guide near the valve seat (14) then presenting a variable obstruction to the air flow independently of the position of the poppet valve (16) in relation to the valve seat (14).

Abstract: An intake or exhaust valve assembly for use in a four cycle internal combustion engine including a primary poppet valve (12), said primary poppet valve (12) having at least one aperture (12b) disposed through its valve body and a secondary poppet valve body (14) mounted to seal when engaged to the primary valve body (12), said secondary valve body (14) having at least one aperture (14b) and a biasing means (16) for moving the secondary valve body (14) away from the primary valve body (12) during the initial opening process when the primary valve (12) is accelerating to its opened position. In the closed position of an intake port (12a), the primary valve apertures (12b) are not aligned with the secondary valve apertures (14b) thus forming a sealed closure across the port (12a). During the opening process of the intake cycle the biasing means (16) moves the secondary valve body (14) away from the primary valve body (12), thereby permitting intake charge to flow through the apertures (14b, 12b) disposed in the primary and the secondary valve bodies. In continuation during the final travel of the primary valve (12) to the full opening said secondary valve (14) is unseated by a stop causing the secondary valve to travel in unison to the maximum valve lift position, greatly increasing the volumetric efficiency of the engine.

Abstract: The invention relates to engine-building engineering. The inventive valve-timing gear comprises a common intake-exhaust disc valve (1) and intake (5) and exhaust (7) channels. A shutter (4) is arranged in the channel (5) and shutter (6) in mounted in the channel (7). Said shutters are used for dividing intake and exhaust processes. The rotation axis of each shutter (4, 6) is offset with respect to the symmetry axis. A counterweight (14) is embodied on each shutter on the side of offset. The inventive structural design makes it possible to reduce unbalanced inertia forces during the shutter motion, decrease vibrations, the drive wear and energy consumption.

Abstract: An intake and exhaust device for an internal combustion engine with direct injection comprises an intake and exhaust valve (11) with a stem (13), a head (12), and a seat (24) facing a combustion chamber (CC) of the engine (M), and intake duct (42) for the intake of air into the combustion chamber (CC), and an exhaust duct (38, 57) for the discharge of the exhaust gases, the exhaust duct (38, 57) being connected to the intake duct (42) upstream of the valve seat (24). The exhaust duct (38, 57) is arranged so as to be coaxial with the valve (11) and the intake duct (42) extends radially. The connection between the intake duct and the exhaust duct (38, 57) is in the vicinity of the seat (24) of the valve (11) so that the exhaust gas-flow conveyed through the connection has a radial velocity component directed towards the valve stem (13). The air is drawn in from the intake duct (42) as a result of the gas-flow passing through the exhaust duct (38, 57) during the exhaust phase and as a result of the movement of a piston (P) in the cylinder during the intake phase.

Abstract: A pneumatically actuated valve assembly for use as intake and/or exhaust valves on two- ­or four-stroke internal combustion engines. The assembly includes a valve (100), valve housing (200), and compressed gas distribution and timing mechanisms (Figures 5-8). The valve (100) is comprised of a short light weight hollow cylindrical body with a capped lower end and an opened upper end. The valve is further defined by a plurality of ports (104) adjacent to the lower end and a collar (198) encircling the body adjacent the upper end. The valve housing (200) is hollow and tubular having a larger diameter upper section and a smaller diameter lower section in which the valve (100) slides up to close and down to open. The housing (200) further includes hollow channels which direct compressed gas, managed by the distribution and timing mechanism, alternately towards the areas above and below the valve collar at regular intervals to open and close the valve, respectively.
