    • 1,126,157. Air filter. GENERAL MOTORS CORP. 24 Aug., 1967 [29 Sept., 1966], No. 38969/67. Heading BIT. [Also in Division F1] A carburettor air filter 10 incorporates a valve 46 actuated by a vacuum motor 54 in response to intake manifold suction to control the admixture of hot air from an inlet 42 with ambient air from an inlet 34 the action of the suction on the motor 54 being modified by a temperature responsive air bleed valve 82 which bleeds air into the motor at a rate which increases with intake air temperature. The valve 46 is hinged at 48 and movable from a position closing the hot air inlet 42 to a position closing the cold air inlet 30. Intake manifold suction is conducted by a pipe 72 to a member 68 Fig. 3 (not shown) containing a restriction (74) and connected by a pipe 64 to the motor 54. The temperature responsive device bleeds air into the pipe 64 through pipe 76 and comprises a valve 88 Fig. 4, actuated by a bimetallic strip 90 situated in the filtered air chamber of the filter 10. At low temperatures valve 88 is closed, wherebymotor 54 actuates valve 46 to open the hot air inlet 42. With increasing temperature valve 88 is opened and valve 46 gradually closes inlet 42. A second ambient air inlet 32 is normally closed by a valve 50 actuated by vacuum motor 56 and opens at full throttle, conditions, the action of motor 56 being unaffected by the air bleed device 88.
