    摘要： An assembly which includes a valve adapted for connection to a source of pressurized gas having a first connector, a regulator for regulating flow of gas from the source and having a second connector, and an automatic shutoff module positioned in the first connector, the module being adapted to shut off the gas flow in response to certain unsafe conditions, e.g., excess ambient temperatures and/or excess gas flow rates. The second connector includes a probe which is receivable by the first connector, and further includes a connector element that is rotatably mounted on the second connector and adapted to engage the first connector to form a secure interconnection between the first and second connectors. The automatic shutoff module includes an activator housing and an activator movably mounted in the activator housing, the activator being normally closed but being abuttingly held open by the probe upon connection. A thermally sensitive member or element is provided that yields upon sensing temperature in excess of about 200 degrees F., thus allowing the module to automatically close, whereby the module shuts off the flow of gas.

    摘要： A pressure regulator (10) includes a changeover regulator (12) with plural inlets (16, 18). Inside the regulator, each inlet has a closure member (62) connected to a diaphragm (100) for control of the closure members (62) in response to pressure inside the regulator (12). Biasing members (56) are stabilized in position by either an apertured plate (102), a cup (104) or both. A changeover handle (19) depresses one spring (56) or the other to bias one closure member (62) open to admit gas from the associated inlet (16 or 18).
