Abstract (en)
[origin: WO0183034A1] A stationary grill has openings (2) through which air can flow and a sliding sealing plate (3) positioned adjacent the grill (1) which has openings which register with the openings of the grill when the ventilator is in an open configuration and lands between the openings which register with the openings of the grill when the ventilator is in its closed configuration. Means are provided for imparting sliding movement to the sealing plate automatically in response to a predetermined elevated temperature. The movement imparting means comprises a spring (12) of bi-metallic material connected between the stationary grill and the sliding plate, the spring operating to resist movement of the sealing plate to retain the grill in its open configuration below a specified temperature and whose length increases at elevated temperatures to move the sliding plate relative to the stationary plate initially partially to close off the openings formed in the stationary plate and ultimately to fully close off these openings. Movement of the sliding plate is reversed as the ambient temperature returns to below the specified temperature.
