Claims

[Scope of utility model registration request]

A spherical tank shell is provided with a pressurized gas supply pipe and a propellant discharge pipe, and the propellant discharge pipe section is provided with a sump section for removing gas or bubbles from being discharged to the propellant discharge pipe, and the pressurized gas supply pipe is provided with a sump section for removing gas or bubbles from being discharged to the propellant discharge pipe. A channel is provided between the pipe and the sump portion, the opening of which faces the inner circumferential side of the tank shell to feed the propellant into the sump portion, and the channel opening has a mesh that captures the propellant in the eye portion. In the fixed surface tension type propellant tank, the mesh portion of the channel is reinforced with a mesh having a wire diameter larger than that of the mesh, and a cylindrical mesh is provided within the sump portion shell and a concentric mesh is provided within the cylindrical mesh. A truncated conical mesh housed in the tank shell is provided, and the sump shell and the required position of the channel are communicated by a vent pipe for discharging gas or bubbles in the sump part into the tank shell. surface tension type propellant tank.
