Abstract
Mechanisms and methods for injecting and sealing pressurized fluid into containment vessels using a divided valve mechanism are disclosed. The invention describes designs and methods in which a valve may be plugged by an actuator, and then the valve and actuator may then be disjoined, allowing the containment vessel to thereby be sealed without the additional mass or volume of the actuation mechanism and without fluid loss from the containment vessel.
Claims14
A system for injecting a liquefied gas electrolyte having a vapor pressure greater than 100 kPa at a temperature of 293.15 K, the system comprising:
- an electrochemical energy storage device (2) comprising:
- a vessel wall (5);
- a vessel cap (4) sealed onto the vessel wall (5), the cap (4) comprising a valve seat (8), a vessel port (12), a vessel seal interface (11), and a valve plug (9) having an elongate member (10A, 10B) extending out of the vessel port (12);
- a vessel volume (7) defined by the vessel cap (4) and the vessel wall (5);
- wherein the vessel port (12) is in fluid communication with the volume (7), and the elongate member (10A, 10B) defines a longitudinal axis (10C);
- and
- an injector assembly (20) comprising:
- an injector seal interface (21) comprising an injector port (22) and a sealing gasket (23);
- a pressurized fluid channel (24) in fluid communication with the injector port (22);
- and
- a valve plug actuator (25A, 25B, 25C) constructed to receive the elongate member (10A, 10B) when the containment vessel (2) is engaged with the injector assembly (20).
