FIELD: machine building.
SUBSTANCE: group of inventions relates to device for a machine of displacement type. Device comprises two mutually continuously movable parts. First part internally has at least two radially inwardly directed wings. Second part has a hub which has at least two radially outwardly directed wings. Portion of the hub between the wings of the second part is in slidable or adjacent contact with a curved, free end portion of the wings on the first part. Curved, free end portion of each wing on the second part is in slidable or adjacent contact with the curved inside wall on the first part which is located between respective ones of two neighbouring wings on the first part. Wings of the second part are movable between respective neighbouring wings on the first part, so as to form chambers which successively increase and decrease, and decrease and increase in volume during the course of a rotation cycle.
EFFECT: group of inventions is aimed at creating a vibration-free, compact and lightweight design.
