The valve plunger includes a valve bottom configured to seal an opening between the valve bottom and an interior opening of the sleeve weldment. The valve also may include a cam configured to force the valve plunger into the interior of the tank vessel to break the seal between the valve bottom and the interior opening of the sleeve weldment.

An emergency response containment vessel for a cylinder includes a vehicle frame and a sealing container carried by the vehicle frame. The sealing container includes a barrel body including an opening, a locking module, and a cover module. The locking module includes a fixed seat surrounding the barrel body and adjacent to the opening, a ring seat connected rotatably relative to the fixed seat between lock and unlock positions, and a driving device driving the ring seat to rotate. The ring seat includes a plurality of alternating blocks and notches and an annular groove. The cover module includes a connecting arm pivotably connected to the fixed seat and a cover connected to the connecting arm, removably covering the opening, and including a plurality of engaging portions removably received in the annular groove and respectively aligned with and misaligned with the notches when the ring seat is at the unlock and lock positions, respectively.

An organic composite gas storage tank 100 comprises a hollow central portion 106 which is substantially cylindrical and formed integrally with first and second end portions 102, 104, and which defines a longitudinal tank axis 301. The first end portion comprises a hollow truncated conical region which meets the hollow central portion at a first end thereof, the outer and inner radii of the hollow truncated conical region decreasing in a direction along the longitudinal tank axis away from the hollow central portion. An organic fibre winding 107 extends at least between axial positions which coincide with the hollow truncated conical region of the first end portion and the hollow central portion respectively. The first end portion has a higher axial strength than that achievable for hemispherical end portion of a tank of the prior art.

A hydrogen storage tank of a vehicle includes a housing defining an inlet/outlet opening, a control assembly extending into the housing through the opening and comprising a plurality of sensors, and a controller configured to receive signals from the plurality of sensors. The controller of the hydrogen storage tank is configured to, in response to a request for a handshake signal, initiate sending the handshake signal, and in response to the vehicle being started, initiate periodically sending data indicating parameter values received from the plurality of sensors.

An organic composite gas storage tank 300 comprises a hollow central portion 306 which is substantially cylindrical and formed integrally with first and second end portions 302, 304, and which defines a longitudinal tank axis 301. The first end portion comprises a hollow truncated conical region which meets the hollow central portion at a first end thereof. The hollow central portion comprises first and second hollow truncated conical portions 306A, 306B, the external radius of a given hollow truncated conical portion decreasing in a direction towards a corresponding end portion. The tank comprises an organic composite fibre winding extending between first and second positions along the length of the tank which coincide with the first and second hollow truncated conical portions of the hollow central portion respectively, biassing these portions together and increasing the axial strength of the central portion.

An organic composite gas storage tank 100 comprises a hollow central portion 106 which is substantially cylindrical and formed integrally with first and second end portions 102, 104, and which defines a longitudinal tank axis 101. The first end portion 102 comprises a hollow truncated conical region 102A which meets the hollow central portion at a first end thereof, and a cylindrical region 102B which meets an end of the hollow truncated conical portion remote from the hollow central portion. An organic fibre winding 107 extends at least between axial positions which coincide with the hollow truncated conical region of the first end portion and the hollow central portion respectively. A hollow metal end-fitting 120 has a hollow truncated conical portion 124 embedded within the wall of the hollow truncated conical region of the first end portion, providing a long leakage path around the metal end-fitting.
