A casing for gas including a first channel section through which gas flows and a second channel section intersecting with the first channel section, the first channel section having an intersecting part that intersects with the second channel section, the intersecting part being formed to have a rounded quadrangular cross section and having a flat part, the second channel section intersecting with the first channel section to open at the flat part.

Casing for gas, and tank valve device

There is provided a check valve capable of effectively suppressing the generation of chattering. The check valve includes: a housing including an inlet channel, a valve chest, and an outlet channel; a seat member provided around the inlet channel, the seat member including a seat portion; a valve element pressed against the seat portion to close the inlet channel; a biasing member configured to push the valve element toward a valve seat; a guide portion provided at the housing and configured to guide the valve element when the valve element moves in an axial direction; and a damper chamber communicating with the valve chest through a space between the valve element and the guide portion, the damper chamber being configured to attenuate axial moving force of the valve element. The biasing member is arranged in the valve chest.

Check valve

A thrust generating apparatus which is positioned under water and configured to generate a thrust by ejecting water includes a duct-shaped stator provided with a plurality of armature coils, and a plurality of ring-shaped rotors which are arranged radially inward of the stator and provided with permanent magnets respectively corresponding to the plurality of armature coils, wherein the plurality of rotors are arranged in series in a rotational axis direction thereof and each of the rotors has a propeller vane protruding radially inward. A thrust generating apparatus is capable of outputting a high driving power without increasing a propeller diameter.

Thrust generating apparatus

A thrust generating apparatus is configured to generate thrust by ejecting water. The thrust generating apparatus includes: a first water lubricated bearing opposed to one side surface and outer peripheral surface of rotor main body and supports a thrust and radial load; a second water lubricated bearing opposed to the other side surface and outer peripheral surface of rotor main body and supports the thrust and radial load; a first water intake port that opens toward a portion of a channel; a second water intake port that opens toward another portion of the channel; a first water conveyance tube through which the water having flowed through the first water intake port is guided to the second water lubricated bearing; and a second water conveyance tube through which the water having flowed through the second water intake port is guided to the first water lubricated bearing.

A water flow electricity generating device includes: an annular stator in which a coil is provided; a permanent magnet that causes a magnetic force to act on the coil; a rotor main body that is disposed on an inner circumferential side of a stator core to support the permanent magnet; a blade support unit that is provided on a front side of the rotor main body; a rotor that includes a rotating blade projecting radially outward from the blade support unit; and water-lubricated bearings that are provided in the stator while being opposed to the rotor main body, the water-lubricated bearings supporting loads in a thrust direction and a radial direction. The blade support unit is disposed on a front side of the rotor main body, and the rotor includes a float unit that is provided on the front side of the rotor main body.

Water flow electricity generating device

A thrust generating apparatus is provided under water and configured to generate thrust by ejecting the water. A rotor main body includes: a first member including a side surface and outer peripheral surface which are opposed to a first water lubricated bearing; a second member including a side surface and outer peripheral surface which are opposed to a second water lubricated bearing; and a third member including a supporting surface contacting an inner peripheral surface of a rotor core. The first to third members are fixed to one another so that each member is detachable.
