Variable geometry power transfer for fluid flow machines

A fluid flow machine, comprising:

• a casing including a cylinder and a crankshaft support;
• a piston slidably disposed in the cylinder for reciprocating along an axis of the cylinder;
• a crankshaft including a main bearing journal rotationally supported in the crankshaft support, a crankpin radially offset from an axis of the main bearing journal and a crank web connecting the main bearing journal and the crankpin;
• a multi-linkage connecting rod mechanism comprising:
• a connecting rod having a first end connected to the piston and a second end opposite the first end, the connecting rod for reciprocating with the piston;
• a first hinge link including a first end pivotally connected to the connecting rod second end and a second end opposite the first hinge link first end;
• a crankpin link including a first end pivotally connected to the first hinge link second end and a second end rotationally connected to the crankpin;
• a force transfer mechanism connecting the multi-linkage connecting rod mechanism to the casing for transferring a vertical piston force into a horizontal crankpin force.
