Abstract:
PROBLEM TO BE SOLVED: To provide a container that reduces foam while fluid is poured thereinto.SOLUTION: A fluid transfer assembly and methods of fluid transfer are described. In one aspect, the fluid transfer assembly includes a fluid container having an opening in the bottom, a coupling device attached to the fluid container at the opening, and a filling device. The coupling device may include a valve biasing the coupling device in a closed fluid-tight position via magnetic attraction of opposing first and second components, each of the opposing first and second components including a magnetic material. The filling device may include a rigid member with a perimeter smaller than a perimeter of the fluid container opening, the rigid member including a passage along a longitudinal axis and one or more apertures through a sidewall in fluid communication with the passage, such that the coupling device is transitioned from the closed fluid-tight position to an open position by pressing the rigid member against one of the opposing first and second components, thereby placing the apertures in fluid communication with the interior of the fluid container.

PROBLEM TO BE SOLVED: To provide a differential pressure control valve capable of reducing pressure loss, and capable of achieving improvement of durability and miniaturization.SOLUTION: The differential pressure control valve 100 includes a valve seat 110, a valve body 120 positioned in a downstream side with respect to the valve seat 110 and opening and closing a valve hole 111 by being seated or separating with respect to the valve seat 110 in response to a pressure difference between an upstream side and the downstream side, and a guide member 130 fixed to the valve seat 110 and guiding the valve body 120. The valve seat 110 is made of a magnetic material. The valve body 120 has a cover body 121 made of a magnetic material capable of closing the valve hole 111 by being seated on the valve seat 110, and a guiding member 125 made of a non-magnetic material to be guided by the guide member 130. A permanent magnet 150 is provided in one of the valve seat 110 or the cover body 121, and the valve body 120 is urged so as to approach the valve seat 110 by attraction of the permanent magnet 150. The permanent magnet 150 is attached to a position outside a region in which the valve body 120 is seated or separated with respect to the valve seat 110.
