Claim 0:
1. A pneumatic valve for attachment to a source of high pressure gas, the pneumatic valve comprising: a valve body comprising a gas inlet in fluid communication with an inlet chamber and a gas outlet in fluid communication with an outlet chamber; a rupturable membrane extending across the gas inlet; a membrane support element slidably supported in the valve body for movement between an extended position and a retracted position, the membrane support element having a lower end engageable, in the extended position, with the rupturable membrane to support the rupturable membrane against rupture; the valve body comprising a bore located between the gas inlet and the gas outlet, the membrane support element extending through the bore and one or more gas supply passages extending from the inlet chamber to the outlet chamber bypassing the bore for providing a gas flow path from the gas inlet to the gas outlet; and the membrane support element being configured to be movable from the extended position to the retracted position to permit the rupturable membrane to rupture under the pressure of the high pressure gas, the lower end of the membrane support element in the retracted position being positioned within the bore whereby the lower end of the membrane support element and the bore together form a pocket for receiving a ruptured portion of the rupturable membrane.
