Abstract
Rotary pump of which the body (1) defines a closed cavity having a substantially oval cross-section, wherein a rotor (11) provided with vanes is mounted in an eccentric position. According to the invention, the rotor (11) is rotationally mounted about the axis of a main semicylindrical chamber (4) of the body (1) of the pump and carries fixed vanes (12, 13) distributed at equal angular intervals and coming in soft friction contact with the wall of said main chamber, whereas the cavity contains, opposite to the latter, a movable valve (18) which is orientated in the direction of the axis of the main chamber (4) and closes completely, in said position, the opening formed between the surface of the rotor (11) and the cavity wall portion which is facing; said valve (18) effecting, in synchronism with the rotation of the rotor, a cyclic clearing motion allowing each time the passage of a vane (12) or (13) of the rotor (11) while providing for a soft friction contact between the valve (18) and the vane.
