A safety valve device in a gas burning apparatus includes a valve body and an adjusting member. The valve body has an inlet port and an outlet port and defining a receiving room disposed between the inlet port and the outlet port. The receiving room opens to and in communication with the inlet port and the outlet port. The adjusting member is received by the receiving room. The adjusting member deforms in responsive to temperature from a first shape when in a normal mode into a second shape when in a protection mode and vice versa. The adjusting member is in the normal mode when experiencing a temperature not greater than a set temperature. The adjusting member is in the protection mode when experiencing a temperature greater than the set temperature.

A combustor for a gas turbine, including: a combustor chamber; a casing enclosing the combustor chamber and defining an area therebetween for passing compressor discharge air into the combustor chamber for use in combustion; and at least one passive bypass valve for selectively extracting a portion of the compressor discharge air from the area between the combustor chamber and the casing to adjust a temperature in the combustor.

A stand-alone gas-fired smoker constitutes a cabinet for holding food products to be cooked. A gas burner in the bottom of the cabinet is connected to a source of flammable gas by means of a variable gas valve. The gas burner heats the cabinet and thereby cooks the food products. An oil filled temperature sensing bulb is connected by means of a capillary tube to the variable gas valve in order to modulate the gas delivered through the variable gas valve to the gas burner and thereby modulate the temperature within the cabinet. A safety/ignition valve is connected between of the gas source and the variable gas valve. The safety/ignition valve is connected to a flame sensor, and the safety/ignition valve closes if the flame sensor senses that the gas burner has been extinguished.

A combustor for a gas turbine, including: a combustor chamber; a casing enclosing the combustor chamber and defining an area therebetween for passing compressor discharge air into the combustor chamber for use in combustion; and at least one passive bypass valve for selectively extracting a portion of the compressor discharge air from the area between the combustor chamber and the casing to adjust a temperature in the combustor.

The aim is to provide a gas control valve in which the specified desired value range can be subsequently shifted easily in order to optimize the range of settable temperatures for the heating device without exceeding the device- and/or installation-specific admissible use conditions. To this end, a setting element (17) which serves to change the position of a temperature-sensitive element (8) and thus to actuate a switch for activating a valve has a threaded part (12) that is screwable into the housing (1) of the gas control valve. In this case, the two are connected together in a rotationally secure manner via a releasable locking mechanism, wherein a tubular latching part (14) that is firmly connected to the threaded part (12) is arranged between the pot-like setting element (17), partially surrounding the threaded part (12) with a recess (18), and the threaded part (12). By way of a stop element (16) that protrudes from the end side, the latching part (14) projects into a guiding contour (19) which is formed by an end-side aperture located in the setting element (17).

A thermostat for gas-powered cooking appliances includes a body having an inlet conduit and an outlet conduit that respectively receive and supply a gas flow, and a chamber in fluid communication both with the inlet conduit, and also with the outlet conduit either directly, through a main opening formed at one end thereof, or indirectly, through a secondary conduit formed in the body of the thermostat, which reaches the outlet conduit bypassing the main opening. A valve that adjusts gas flow rate is coaxially fitted in the chamber and has a position that is controlled by an expandable member of a thermostatic bulb of the thermostat. The valve is axially deformable beyond a predefined load threshold and compensates for dilations of the expandable member under a normal operating condition, absorbing axial forces exerted by the thermostat knob when rotated to switch off a burner driven by the thermostat.
