Top Max Piston head for Sun Power MP7 with TPMP7D derlin

Top Max MP7 Piston head Sun Power with derlin bearing TPMP7

review

The SUNPOWER piston head is CNC made in DELRIN on specific measurements by TopMax Elaborazioni. The DELRIN structure makes this piston head reliable, long-lasting and incredibly suitable for any type of configuration. The SUNPOWER piston head is made with axial-internal anti-vacuum holes and radial outlet holes, which allow for better distribution of the air on the sealing O-RING, speeding up its expansion in the compression phase. The size and position of the radial holes is specifically designed to obtain an optimal compression phase of the O-RING while maintaining stability, constancy and precision in the pull.

The SUNPOWER piston head is CNC made in DELRIN on specific measurements by TopMax Elaborazioni. The DELRIN structure makes this piston head reliable, long-lasting and incredibly suitable for any type of configuration. The SUNPOWER piston head is made with axial-internal anti-vacuum holes and radial outlet holes, which allow for better distribution of the air on the sealing O-RING, speeding up its expansion in the compression phase. The size and position of the radial holes is specifically designed to obtain an optimal compression phase of the O-RING while maintaining stability, constancy and precision in the pull.


The shape of the front part of the SUNPOWER piston head has been studied to further reduce the stress due to the impact with the cylinder head PAD even at R.O.F. elevated. The SUNPOWER head does not have the double sealing/centering O-RING, but has a small recess which decreases the contact surface with the inside of the cylinder, to reduce friction to a minimum. The product is completed by the insert in ERGAL and DELRIN for fixing the piston head on the piston.

The SUNPOWER piston head has a narrow compression chamber to have a faster opening time of the O-RING in compression and to guarantee the full compression of the cylinder's air volume almost instantaneously.

The STRESS-TESTS carried out on the SUNPOWER piston head were carried out with higher springs than those required by law, so the product will guarantee you reliability and performance even with more stringent configurations. To obtain maximum performance, it is recommended to combine it with the TopMax cylinder head.
