The mechanism is of good wearlessness and energy efficiency.

Industrial – Reliably high output and low wear, high emissions.

Said piston pump device is designed to exhibit little wear and generate little noise.

This contact system is easy and economical to produce and ensures reduced contact erosion.

In order to provide a wear-free, self-centring inner ring (32), the ring is designed as a split ring with two opposing ends (44) and a spring element (52) for spreading the split ring.

Owing to said pre-wearing (setting), little additional wear in the locking area occurs during operation of the internal combustion engine.

Polyimide resin compositions that contain an aromatic polyimide, graphite and a sepiolite filler, or a mixture of a sepiolite filler and a kaolin filler, are found to exhibit low wear and high thermal oxidative stability.

The method has a low consumption of coal, low equipment attrition, a high heat value of produced coal gas.

A stationary working surface (22) of a one roll microcreper member (10) is of plastic resin having low wear- and friction- properties.

As a result, the CVT transmission is characterized by little wear over a high torque range.
