Presentation of the Mechanism in the Cross

The cross-machine has frequent uses in mechanical assemblies, automation, robotics and mechanisms with various uses. In the present paper we want to present this type of mechanism with its main, geometric, cinematic, strengths and propose its study in its possible use as an internal combustion engine. In this novelty, the mechanism will have two types of operation, one when operated from the crank (a compressor operation) and another when actuated from the piston (a motor operation). The forces will be presented along with their distribution (how the forces are distributed from one element to the other) in both modes of operation, compressor and engine.
