Kolvstängerna

Kolvstängerna, sometimes referred to as piston rods, are essential components in various mechanical systems, primarily within reciprocating engines and hydraulic or pneumatic cylinders. Their fundamental role is to connect the piston, which moves back and forth within a cylinder, to an external mechanism or load. This connection allows for the transmission of force and motion.

In an internal combustion engine, the kolvstång is attached to the piston on one end and to the crankshaft via a connecting rod on the other. As the piston is propelled by the combustion of fuel, the kolvstång transmits this linear motion, which the connecting rod then converts into the rotational motion of the crankshaft. This process is crucial for generating power.

In hydraulic and pneumatic systems, kolvstängerna are typically attached to the piston within a cylinder. The movement of the piston, driven by pressurized fluid or air, causes the kolvstång to extend or retract. This linear motion can then be used to operate machinery, lift loads, or perform other work. The kolvstång must be strong enough to withstand the forces exerted by the piston and precise enough to ensure accurate operation of the connected mechanism. They are often made from high-strength steel and are carefully machined to reduce friction and wear within the cylinder.
