Definitions

  • U.S. Patent 4,011,842 defines a four cylinder piston engine that utilizes two double ended pistons connected to a T-shaped T-shaped connecting member that causes a crankshaft to rotate.
  • the T-shaped connecting member is attached at each of the T-cross arm to a double ended piston.
  • a centrally located point on the T-cross arm is rotatably attached to a fixed point, and the bottom of the T is rotatably attached to a crank pin which is connected to the crankshaft by a crankthrow which includes a counter weight.
  • the assembly includes at least two joints, each joint coupling one of the drive arms to one of the pistons and providing four degrees of freedom between the drive arm and the piston, the four degrees of freedom being a first degree of freedom that includes rotation about the drive arm axis, a second degree of freedom that includes sliding along the drive arm axis, a third degree of freedom that includes pivoting about an axis perpendicular to the drive arm axis, and a fourth degree of freedom that includes sliding in the direction of the perpendicular axis, wherein each joint comprises an outer member coupled to the piston and an inner cylindrical member mounted within the outer member such that the inner cylindrical member slides along the perpendicular axis to provide the fourth degree of freedom.
  • the pistons may be double ended pistons.
  • the transition arm is coupled to each of the double ended pistons at approximately a centre of each piston.
  • FIG. 10 is a side view of engine 30 showing the exhaust manifold 56, intake manifold 56a and carburetor 56c. Pulleys 50a and 50b with timing belt 51 are also shown.
  • FIG. 16 shows piston arm 116 in sleeve bearing 117.
  • Sleeve bearing 117 is in pivot pin 115.
  • Piston arm 116 can freely rotate in sleeve bearing 117 and the assembly of piston arm 116, Sleeve bearing 117 and pivot pin 115 and sleeve bearings 118a and 118b rotate in piston 110, and piston arm 116 can moved axially with the axis of sleeve bearing 117 to allow for the linear motion of double ended piston 110, and the motion of a transition arm to which piston arm 116 is attached.
  • barrel 414 Because outer barrel 420 is fixed, the rotation of barrel 414 causes barrel 414 to move linearly along axis, A, arrow 403. Barrel 414 is positioned between a collar 422 and a gear 424, both fixed to a main drive shaft 408. Drive shaft 408 is in turn fixed to flywheel 322. Thus, movement of barrel 414 along axis, A, is translated to linear movement of flywheel 322 along axis, A. This results in flywheel 322 sliding along axis, H, of drive arm 320 of transition arm 310, changing angle, ⁇ , and thus the stroke of the pistons. Thrust bearings 430 are located at both ends of barrel 414, and a sleeve bearing 432 is located between barrel 414 and shaft 408.
