ABSTRACT:
An intake air temperature control device for mixture-compressing internal combustion engines having an inlet flapper proportioning the flows of cold and preheated raw air into a duct junction and into raw air mixing duct, the flapper-adjusting wax thermostat being arranged inside a thermostat chamber into which branch flows of cold and preheated raw air are admitted through two calibrated branch inlets. A narrow annular gap through which the combined branch flows must pass assures an integrated response of the thermostat to changing temperatures and air intake speeds. A lost-motion drive connection and a biasing member produce a full-load correction of the adjusted temperature. The flapper drive members may have valve edges which cooperate with the calibrated branch inlets to open and close the latter.
