Abstract
A fluid flow machine includes a casing including a cylinder and a crankshaft support. A piston is slidably disposed in the cylinder for reciprocating along an axis of the cylinder. A crankshaft includes 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 is connected between the piston and crankpin and includes a connecting rod, a first hinge link and a crankpin link pivotally connected to each other. A force transfer mechanism connects the multi-linkage connecting rod mechanism to the casing for transferring a vertical piston force into a horizontal crankpin force.

A fluid flow machine, comprising:
- a casing including a cylinder and a crankshaft support;
- a piston slidably disposed in the cylinder for reciprocating along the cylinder;
- a crankshaft rotationally supported in the crankshaft support and including a crankpin radially offset from an axis of the crankshaft;
- 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 crankpin link including a first end pivotally connected to the connecting rod 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;
- wherein the multi-linkage connecting rod mechanism includes a first gear portion and the force transfer mechanism includes a second gear portion engaging the first gear portion in a meshing connection such that the multi-linkage connecting rod mechanism pivots with respect to the force transfer mechanism as the connecting rod reciprocates.
