The piston is made of POM C (technopolymer with high mechanical properties and very low coefficient of friction). The gear is presented with the second missing tooth and with the third already reduced by 3 tenths of a millimetre, as this configuration predisposes the piston itself to the correct angle of engagement (AOE) and allows its use at high speeds. The plain bearings are designed to minimize friction and retain lubricant over the long term. The gear arrangement is decentralised to prioritise the connection between the piston teeth and the sector gear teeth. Longitudinal stiffeners on the sides of the teeth increase the robustness of the piston and prevent the gear from contacting the inner wall of the cylinder. Special ribs reduce the contact area between the spring and the inner part of the piston body, and consequently the friction between the metal and the technopolymer during contraction and elongation due to the firing cycle is also reduced.
