This patent describes a piston ring that is claimed to provide reduced friction and wear. The design allows independent adjustment of the parameters controlling friction and wear to eliminate the trade off between low friction and low wear typical of prior art rings. The contact interface area betwe

## Cross -section of the mechanical seal with pressurized feed to the seal face described in WO 2006/051702, and a detail of the annular face grooves. Device provided with a movable seal system Applicant/Inventor: A. Gaide (Switzerland) This patent describes a moveable seal that is an essential c
the rotor becomes considerably spaced from the stationary seal ring. The frictional engagement of the secondary seal O-ring prevents the seal ring from tracking the rotary seal ring, and thus from closing this gap. This problem is exacerbated when the mechanical seal is shut down, and the : rotor ax
