APEX SEAL CONSTRUCTION

BHE011011910T03

• The special iron cast apex seals have been electronic beam processed to improve abrasion resistance on the trochoid friction surface.

• The apex seal is comprised of two parts including a side piece set on the sharp end of an apex seal. The apex seals maintain a gas seal while sweeping the trochoid surface by the combined force of the apex seal springs and centrifugal force of the rotor rotation.
