The block of a butterfly valve provides regulation of idling and change of amount of the air coming to the engine. The block consists of the electric motor and the electrometric sensor of provision of a butterfly valve with two conducting paths.

Idling the provision of a butterfly valve is established depending on the set idling rotation frequency which depends on the number of the included powerful consumers of the electric power (conditioner) and operating conditions of the engine (air temperature and cooling liquid).

By pressing an accelerator pedal the butterfly valve opens on the corresponding corner.

At the same time, for improvement of convenience of driving opening of a butterfly valve not in direct ratio to the operating influence of the driver.

To exclude breakthroughs, to facilitate gear shifting and to ensure safety, the block of a butterfly valve allows to change torque of the engine.
