Valve e.g. three-way valve, for air supplying circuit of e.g. heat engine, in motor vehicle, has rotary unit moved inside body in manner to control passage of air via openings with rule defined according to angular position of rotary unit

摘要

The valve (30) has a body (32) comprising an entirely open bottom surface (44), a side wall (42) and three inlet or outlet openings (36-40). The opening (36) is formed on the bottom surface. The other two openings (38, 40) are formed on the side wall. A rotary unit (34) is moved inside the body in a manner to control passage of air through the openings (38, 40) with a rule defined according to an angular position of the rotary unit in the body. The rotary unit has a rotation axis, in which the openings (38, 40) comprise an elongated shape along the rotation axis. An independent claim is also included for a method for controlling an engine using an air supplying circuit.
