<p>The gas burner control unit, partic for gas-operated refrigerators, is based on a body with a control-cock drilling between inlet and outlet, a cock with gas passages and devices for adjusting this. The cock has shut-off, low- and high-flow settings, based on a predetermined gas pressure. The former gives reduced, the latter full-load output. An additional passage is embodied, giving an intermediate output at the predetermined pressure and full-load output at a second, higher, one. The cock adjusting equipment includes a device for preventing the use of the high-flow setting when operating at the higher pressure.</p> |
