Cold air is admitted through the open end 26 of an adjustable silencer tube 23 and warm air past the engine manifold 3. The valve 28 is displaced about a pivot 29 by a thermostatically operated plunger bearing against an abutment 31 of a lever 30 held by a spring 36. The filter is of the oil bath type and has a baffle 10 dividing the incoming air into ducts 8, 9 serving as silencing chambers. Specification 756,640 is referred to. |
