摘要： An internal combustion engine with an exhaust valve formed in the upper surface of the piston and driven by a valve stem connected to the engine crankshaft by an operating arm mounted parallel to the connecting rod and axially movable with respect thereto by means of a cam follower and rolling engagement with a cam on the connecting rod journal of the crankshaft. At least one exhaust tube is mounted in the cylinder and secured to the piston and more specifically to an exhaust chamber formed in the piston below the exhaust valve. The exhaust tube is a telescoping tube which extends from the piston to a wall of the engine block.

摘要： In an axial-piston engine of the type known as a "wabbler" engine, in which the motion of the pistons is transferred to a straight main shaft by means of a non-rotating element (referred to as the "wabbler") which nutates as the shaft rotates and transfers the motion to the pistons via arms at its periphery, a design of the wabbler in which the wabbler is made in two or more parts so as to enclose a swashplate on the shaft, with thrust bearings between the wabbler and the swashplate (which latter is fixed to the shaft). The parts of the wabbler are rigidly connected together, so as to maximise the bending strength of the assembly in resisting the thrust loads from the pistons, and to facilitate the transfer of the loads to the bearing surfaces so as to avoid excessive localised loading of the bearings. To this end, the mating surfaces between the parts of the wabbler have features such as serrating or grooving which by interlocking action enhance the transfer of shear forces, such that the bending strength which would have existed had the wabbler been all in one piece is retained to the greatest possible degree.In this design, the body of the wabbler essentially consists of a short "cylinder" with heavy annular end plates; the spacing-apart of these ends provides a superior means of reacting the cantilever bean loads from the arms and of distributing these loads over the bearing surfaces.

摘要： An internal combustion engine comprises a cylinder of stepped configuration having a working portion and a pumping portion and a piston of stepped configuration having a working portion and a pumping portion, the working and pumping portions respectively co-operating to define a combustion chamber and a pumping chamber each of which varies in volume upon reciprocation of the piston in the cylinder. Air is admitted to the pumping chamber through a duct from where, on volume reduction thereof, if passes via a plurality of passages and a one-way valve into a transfer chamber. On volume expansion of the combustion chamber, air in chamber is discharged therefrom via a plurality of passages, common discharge port and valve to scavenge the combustion chamber and provide combustion air. The valve may be self-acting or operated by a crankshaft controlled push-rod. A delivery pump operated pneumatically under the influence of the pumping chamber to deliver fuel or a combustible mixture to inlet passage is also disclosed.

摘要： An improved two-cycle internal combustion engine with a novel intake, exhaust and piston arrangement in which a fresh charge for combustion is advantageously transferred through the piston and all valves in the engine operate in response to changes in dynamic pressure generated within the engine. The piston includes at least one charging passage through its top surface with a pressure sensitive valve affixed to the top surface of the piston for preventing flow of a fresh charge through the charging passage in the absence of a greater pressure differential caused by the intake charge against the undersurface of the pressure sensitive valve. Advantageously, the pressure sensitive valve is deflected upwardly to provide passage of a charge through the charging passage in the presence of a sufficient pressure differential caused by the intake charge against the undersurface of the pressure sensitive valve, and the charging passage and pressure sensitive valve coact to direct flow of the incoming charge toward the walls of the engine cylinder away from the exhaust. Also advantageously, the intake and exhaust can be directly controlled by the piston.

摘要： A variable-compression internal-combustion engine has a two-stage cylinder with a relatively large diameter at a first-stage, supercharge end, which is also a power-takeoff end, than at a second-stage, combustion end of the cylinder. Intake air is drawn into the first-stage, supercharge end of the cylinder by a matching larger-diameter, first-stage, supercharge end of a two-stage piston during a compression stroke of a two-stroke cycle of the two-stage piston. During a power stroke, intake air is directed into and contained under pressure in an air-transfer passage that is positioned circumferentially and externally around an outside periphery of a bottom end of the first-stage cylinder. At a bottom end of the power stroke, intake air is directed from the air-transfer passage into a transfer conveyance extended from the supercharge end to tile second-stage head of the two-stage piston where the intake air is venturi-accelerated to the second-stage head of the two-stage cylinder while exhaust escapes through exhaust ports at a bottom of the second stage of the two-stage cylinder. Cylinder heads can be variable in distance from top dead center of piston travel to regulate compression ratio as desired for different operating conditions. Reciporcative travel of a plurality of the two-stage pistons is convened to rotary motion preferably by a pinch plate in working relationship to an angled cam plate. The pinch plate cam-drives the angled cam plate with a large contact surface for long wear life. Other rotational means can be employed.

摘要： A two-stroke cycle internal combustion engine including a crankshaft, a connecting rod pivotally connected to the crankshaft, a fuel induction system and spark plug or the like. The cylinder has a closed head end and a closed rearward end and a piston within the cylinder defines a combustion chamber as well as a charging chamber. A plurality of radial inlet ports formed in the cylinder wall is normally closed by the piston but is opened to the charging chamber when the piston passes through its top dead center position. A plurality of radial exhaust ports also is formed in the cylinder wall and is normally closed by the piston but opened to the combustion chamber as the piston passes through its bottom dead center position. An axial valve port is formed in the crown of the piston to communicate between the charging chamber and the combustion chamber. An operating rod mounted in the cylinder has a valve head formed on its inner end to close the valve port. The other end of the operating rod extends through a sealed axial passage at the bottom of the cylinder end is connected to the connecting rod. When the piston approaches its bottom dead center position, its retraction movement is limited by fluid pressure caused by compressed gas in the charging chamber and accordingly the operating rod disengages from the crown of the piston to open the valve port and admit a charge from the charging chamber to the combustion chamber.
