Abstract
An arrangement for controlling the temperature of the intake air of internal-combustion engines has an intake air filter in which a swivellable control valve is provided that interacts with a pneumatic actuator. The actuator causes an adjustment of the control valve by a bimetallic control device, as a function of the air temperature fed to the internal-combustion engine. A thermostat is provided which, by way of a movable stop, determines the swivel range of the control valve in the direction that closes off the warm-air duct. The thermostat is arranged in a receiving device. This receiving device is fastened in a cold-air duct by a welded connection.
