Hydrostatic rotary piston pump or motor - has slide surfaces with friction reducing coatings of different material

Hydrostatic rotary piston pump or motor - has slide surfaces with friction reducing coatings of different material

The pump/motor can operate according to the blocking slide principal. It has a constant volume/output and rotors, fastened to a drive shaft. Blocking slides, dividing the low and high pressure chambers, engage on the peripheral curved track of the rotors, and move radially in the stator. Slide pairs...

description The pump/motor can operate according to the blocking slide principal. It has a constant volume/output and rotors, fastened to a drive shaft. Blocking slides, dividing the low and high pressure chambers, engage on the peripheral curved track of the rotors, and move radially in the stator. Slide pairs formed from stator (2) and rotors (3), and/or stator and slides (6), have at least one slide surface with a friction-reducing coating. This consists of tin or aluminium, a metal alloy, e.g. lead bronze, or a synthetic material. Two coating slide surfaces have different coatings.
