Problems solved by technology

[0006] However, the different options offered by these devices for controlling the air and / or regulating its temperature are limited since it is not possible to perform control with a second damper and via two channels
[0007] Application EP 1 512 853 also discloses a double restrictor utilizing two rams, each allowing control from one channel, and both rams are permanently actuated so that control from a single channel is not possible

Embodiment Construction

[0081] refer to figure 1 An air supply circuit to a cylinder 100 of a turbocharged internal combustion engine for a motor vehicle can be seen. Air from the outside is passed into the air filter 101 and is then compressed by the compressor 102 of the turbocharger which sends the air into the double restrictor which is the subject of the invention. The body 1 of this double restrictor has an inlet channel 2 through which the air from the compressor passes, and two outlet channels 3 and 4 . It receives commands for controlling the air between the two channels from a computer 103 , called an electronic control unit (ECU). These commands are executed in the form of a displacement of the shutter, which more or less closes the channels 3 and 4 under the action of an electric actuation motor (not shown) and a suitable kinematic system, which Incorporated in the body of the double restrictor. A heat exchanger or cooler 5 is mounted on one of the channels, called the cooling channel ...

Abstract

The invention relates to a double distributor for distributing the intake fluid of an engine, comprising a body in which first and second flow channels are arranged, first and second movable shutters being positioned in said flow channels, said distributor also including an actuator motor and kinematics for simultaneously actuating the first and second shutter, characterised in that the kinematics are arranged so as to distribute the flow passing through the first output channel by rotating the first shutter, provide proportional distribution via the two output channels by simultaneously rotating the two shutters, and distribute the flow passing through the second output channel by rotating the second shutter.

Description

technical field [0001] The field of the invention is that of motor vehicles and, more particularly, of devices for feeding an engine. Background technique [0002] The heat engine of a motor vehicle includes a combustion chamber, typically formed by a plurality of cylinders, in which a mixture of fuel and air is combusted to produce engine work. [0003] Constructions are known in which the flow of incoming fluid, including the air necessary for the operation of the engine, is divided between two channels. One channel carries means for cooling the fluid, while the other channel does not include such means. The channels are then combined at the engine inlet. The throttling device can thereby change the temperature of the incoming fluid before it is introduced into the cylinder, whether more fluid is routed via passages through the cooler (called cooling passages) or via passages bypassing the cooler (called bypass passages or non-cooling passages). cooling channel) transmi...
