Abstract: Apparatus for use in delivery of gas capable of combustion that incorporates a safety valve unit. The safety valve unit closes the flow path of the gas from the source upon occurrence of a fire. The safety valve unit has a valve body, a valve head resiliently biased towards a valve-closure position and a fusible retainer that holds the valve member in a valve open position. The valve body defines a fluid flow passage between an outlet and the valve head. Within the fluid flow passage there is an elongate link member which extends from the valve head to the foot. The foot engages the fusible retainer.

Abstract: A modular coupling system allows a combined gas canister and integral regulator to be used with a wide range of different utilizer devices such as flow meter, conservor or delivery apparatus. A first coupling part is secured to the pressurized gas canister permanently, and carries a combined main delivery valve and venting valve to allow connection of the gas utilizer to the canister by means of a second coupling part formed integrally with or attached to the gas utilizer device by a simple push and twist action which, upon fitting, closes the venting valve; and opens the main delivery valve in sequence.
