The novel long-stroke drive system addresses the limitations of conventional piston crank mechanisms, such as limited stroke-to-bore ratio, uneven leverage, and side thrust, causing wear and tear. This innovative solution ensures near-constant speeds, uniform force on the piston rod, and fewer moving parts, enhancing efficiency and durability. Utilizing a rotating gear's unidirectional input, the system allows the rack to oscillate/reciprocate without reversing the rotor's direction, offering smooth torque transmission and reduced maintenance.

The novel long stroke drive addresses key limitations of conventional piston crank mechanisms, such as limited stroke-to-bore ratio, uneven leverage, side thrust causing wear and tear, and vibrations due to unbalanced masses. It offers near-constant speeds, uniform force on the piston rod, and reduced moving parts, enhancing efficiency and durability. This innovative solution aims to improve performance and reduce maintenance in applications requiring linear or angular oscillating motion.
- Near-constant velocity throughout the stroke: Provides smooth and consistent operation, reducing vibrations and wear on components, which results in enhanced performance and extended lifespan.
- Uniform force on the piston rod: Minimises stress and wear on the piston and associated components, improving durability and lowering maintenance costs.
- Large stroke-to-bore ratio: Enhances efficiency and effectiveness in applications requiring long strokes, providing better performance compared to conventional mechanisms.
- Reduced number of moving parts: Lowers the likelihood of mechanical failures, reduces maintenance needs, and increases overall system reliability.
