Gas delivery system for a pressurized gas cylinder and a quick locking assembly thereof

A gas cylinder assembly for manually connecting a gas cylinder to a fuel cell, the gas cylinder assembly comprising:

• a housing including a first end portion, a second end portion with a bore extending therethrough, and a central portion extending between the end portions thereof, wherein at least one said end portion of the housing is selectively removable from the central portion of the housing to receive the gas cylinder therewithin;
• a handle operatively connected to the first end portion of the housing;
• a pressure regulator with a proximal end portion connectable to the gas cylinder and a distal end portion shaped to extend through the bore and operatively connect to the second end portion of the housing;
• one or more laterally-extending male members operatively connected to the second end portion of the housing and extending inwards in part within said bore;
• and
• a female coupling member shaped to rotatably engage with the one or more laterally-extending male members to enable passage of the female coupling member with said bore, with the pressure regulator being actuated to enable fluid communication between the gas cylinder to the fuel cell only upon the female coupling member being fully received within said bore.

A gas cylinder assembly for connecting a gas cylinder to a fuel cell, the gas cylinder assembly comprising:

• a first pressure regulator including an inlet port connectable to the gas cylinder and including an outlet port, the first pressure regulator being configured to reduce pressure passing therethrough by a first factor;
• a second pressure regulator including an inlet port and an outlet port connectable to the fuel cell, the second pressure regulator being configured to reduce pressure passing therethrough by a second factor which is less than the first factor;
• and
• a quick locking assembly via which the outlet port of the first pressure regulator and the inlet port of the second pressure regulator are selectively connectable.
