A single fill valve for a cryogenic liquid storage vessel. The valve includes a central opening configured to receive a cryogenic liquid and distal and bottom openings configured to direct cryogenic liquid into the cryogenic liquid storage vessel. The valve further includes a plunger and a pin configured to move the plunger and block at least the distal and bottom openings of the single use valve.

A flat bottom ball valve is provided in the present disclosure. According to an example, the flat bottom ball valve includes a valve body, a valve core, a valve rod, a bonnet and a flow path. The valve core is mounted inside the valve body. The valve rod is mounted on two opposite sides of the valve body, perpendicular to a liquid flow direction and capable of driving the valve core to turn over. The bonnet is movably mounted on the valve body and parallel to the valve rod. The flow path is defined inside the valve body and connects two ends of the valve body. The valve core includes a main body part, a connecting part formed by extending symmetrically from two sides of the main body part, an accessory defined on the main body part and a first mounting hole in the connecting part to engage with the valve rod. The valve core swings around the valve rod along a path above the valve rod and is capable of being hermetically engaged with the valve body to turn off/on the flow path. A horizontal center line of the main body part is parallel to a horizontal center line of the first mounting hole in the liquid flow direction of the flow path.

A solenoid valve, in particular for controlling a brake pressure of a wheel brake of a motor vehicle, includes a pole core, an axially moveably mounted armature, a valve element, a closure element, a plunger, and a pressure spring. One end of the armature is associated with the pole core. The valve sealing element is arranged at another end of the armature. The armature has an axial through-opening. The closure element is force-lockingly and/or interlockingly retained in the axial through-opening in a selectable position. The plunger is axially moveably mounted in the axial through-opening, which provides a connection to the pole core in an installation position. The pressure spring is positioned in the axial through-opening and is retained in a pretensioned manner between the plunger and the closure element. The closure element is designed as a three-dimensionally convex element.

A liquid capture valve may have a housing that physically contacts a lid and contains a floating member. The lid can have an inlet and an outlet with the outlet positioned at an apex of a sealing surface. The floating member can be configured to seal the outlet by contacting an outlet edge in response to the housing containing a predetermined volume of liquid.

An apparatus is for controlling a fluid flow. The apparatus has a valve provided with a valve adjuster for controlling a fluid flow through the valve. The valve has a fluid inlet in fluid communication with a fluid inlet conduit, and a fluid outlet in fluid communication with a fluid outlet conduit, for flowing fluid through the valve. The apparatus further has an actuator device capable of undergoing a change in shape, the change in shape of the actuator device providing via a connecting member an attenuated or amplified displacement of a fixation point connected to the valve adjuster, when compared to the change in shape of the actuator device.
