GATE SUPERCHARGER Russian patent published in 2023 - IPC F04C2/344 

FIELD: blower installations.

SUBSTANCE: invention relates to blower installations and can, in particular, be used in fan building. The effect is achieved due to the fact that the vane supercharger, containing a housing, including a cylindrical stator and side flat walls with annular lugs in the central part, a drive shaft coaxial with the cylindrical stator, bearings and a tubular hub with gate blades, valves placed in the holes of the cylindrical stator for passage of the pumped medium, inlet and outlet nozzles, additionally contains radially located closing blades installed in the housing with corner plates fixed to them, holes in the cylindrical stator for accommodating valves in them are made in close proximity to the sides of the closing blades and form two rows around the circumference of the cylindrical stator , one of which contains inlet valves, and the other - exhaust valves, on the outer side of the cylindrical stator there are inlet and outlet manifolds with inlet and outlet pipes and valve boxes placed on them, respectively with covers, the drive shaft is fixed through bearings in the annular lugs of the side flat walls of the housing and is rigidly connected with the help of annular spacers to the tubular hub, at the ends of which there are slotted holes directed along the generatrices, in which the shanks of the gate blades are located. The drive shaft is connected to the shaft of the power drive device by a crank mechanism, one of the side flat walls of the housing has a flange connector with a cylindrical stator, and the flange connector is made with centering pins, seals are placed between the drive shaft and the annular lugs of the side flat walls of the housing, the edges of the radially located in the body of the closing blades are placed in the grooves of the cylindrical stator and the side flat walls and fixed with screws, the side edges of the shanks of the gate blades are placed with pinching in the radial grooves of the annular spacers, direct-flow type valves are installed in the holes of the cylindrical stator.

EFFECT: simplifying the design and improving the performance of the supercharger.
