ABSTRACT:
The invention relates to an adjusting device for the blast pressure in cooling nozzles of a glass tempering apparatus, said device comprising at least two blowers each with its own vane adjuster, blast ducts between the blowers and an air-distribution chamber, and a bypass duct linking the blast ducts. Between blast duct and air-distribution chamber downstream of by-pass duct there is fitted a throttle valve, which is in a throttle position when one blower is running with its vane adjuster partly or completely open. Thus, merely by adjusting said vane adjusters it is possible to cover a pressure range of 5-7000 Pa which is sufficient for glass thicknesses of 4-19 mm.
