FUEL TANK AND ITS INTAKE DEVICE Russian patent published in 2018 - IPC B64G1/40 

FIELD: space technology.

SUBSTANCE: group of inventions relates to space engineering. Fuel tank contains an intake device and a phase separating device. Intake device comprises a body provided with a T-shaped frame, a support ring, a cylindrical side wall, side legs and an outer longitudinal rod. Support ring of the body is fixed on the shelf of the frame. Side wall is fixed to the support ring and covered with a lid. Side posts are evenly spaced around the side wall of the body. Intake device comprises a divider and an inner longitudinal rod. Phase separating device comprises first and second screens, made in the form of truncated cones and connected to each other by large bases through the spacer placed with a clearance relative to the fuel tank shell. Smaller base of the first screen is connected to the support ring, smaller base of the second screen is fixed to the outer longitudinal rod of the intake device. Between the screens of the phase separating device, meridional plates are located, fixed on the spacer of the phase separating device and the side posts of the body of the intake device.

EFFECT: technical result of the group of inventions is the reduction of the mass of unusable fuel residues, increase in reliability of operation and reduction of the mass of the fuel tank.
