Internal combustion engine

Swivel-blade internal combustion engine which produces gas pressure energy for two-cycle and four-cycle operation comprising:

• a reciprocating shaft (24);
• a reciprocating element (9) supported on said reciprocating shaft (24), said reciprocating element (9) having a working surface adapted and positioned to receive the gas pressure energy for producing an oscillating pendulum moment in the reciprocating element, said working surface having a shape which deviates from a rectangular form;
• rocker arm means (16) for converting the pendulum moment into the torque of a crankshaft, said rocker arm means further comprising a swing arm (21) fixed solidly on the reciprocating shaft (24) and an articulated connecting rod (20) connected to the swing arm and to the crankshaft through which the pendulum moment is passed to the crankshaft wherein a change in the compression through a change in the length of the swing arm (21) is achieved by means of eccentricity of the swing arm pin.

• a reciprocating element (9) supported on said reciprocating shaft (24), said reciprocating element (9) having a working surface adapted and positioned to receive gas pressure energy for producing an oscillating pendulum moment in the reciprocating element, said working surface having a shape which deviates from both a rectangular and circular segment form, said working surface having a wider surface area presented at locations more distant from the reciprocating shaft (24);
• rocker arm means (16) for converting the pendulum moment into the torque of a crankshaft (25), said rocker arm means further comprising a swing arm (21) fixed solidly on the reciprocating shaft (24) and an articulated connecting rod (20) connected to the swing arm and to the crankshaft through which the pendulum moment is passed to the crankshaft, said swing arm (21) spanning a pendulum angle .beta.w of a minimum of 90.degree. and a maximum of 130.degree. and having an angle .alpha.p between the swing arm and crankshaft in the reversing position of the pendulum element which moves in a range greater than 0.degree. up to a maximum of 30.degree., and wherein said reciprocating element (9) has a left-hand direction of rotation.
