PARTICLE FEED DEVICE Russian patent published in 2019 - IPC B24C7/00 B24C1/00 B65G53/46 

FIELD: physics.

SUBSTANCE: invention relates to a device for capturing cryogenic particles into a transport fluid in the form of a transport gas flow. Device comprises rotor, cavity formed by cavity wall and cavity lower part, seal, a piston, an inlet connected to a source of a transport fluid medium, an outlet, a flow path of a transport fluid medium and a pressure chamber. Seal comprises a first surface located adjacent to at least a portion of peripheral surface. Piston is movably located at least partially in said cavity. Inlet is connected with transport fluid source. Section of the flow path of the transport fluid medium is formed by means of a seal and a piston, wherein the flow path of the transport fluid medium contains an inlet and an outlet. Pressure chamber is formed by piston and corresponding section of cavity wall and lower part of cavity. Piston and seal are arranged so that pressure inside pressure chamber controls sealing force with which first surface is pressed against peripheral surface.

EFFECT: improved quality of seal.
