FIELD: non-positive-displacement pump.
SUBSTANCE: stator is used for compressor of turbine machine provided with a set of blades which are mounted in the wall for permitting rotation around the axis that defines the rotation surface around the central longitudinal axis of rotation of the turbine machine. The rotation axis is inclined to the plane perpendicular to the central longitudinal axis. The wall is worked in front of the end section of each blade to define spherical section or pocket whose center is located at the rotation axis. The radius of the section is chosen so that to provided minimum space between the end section of each blade and spherical section throughout the range of operation of the blade. The compressor provided with the stator is also proposed.
EFFECT: enhanced efficiency.
