Embodiment Construction

[0067] refer to figure 1 , an example of an environment in which the valve 1 according to the embodiment of the present invention can be used will be described. figure 1 An air supply circuit for a turbocharged internal combustion engine of a motor vehicle 100 is shown. Air taken from the outside enters the air filter 101 and is then compressed by the compressor 102 of the turbocharger, which delivers the air into the valve 1 . The valve 1 has a first duct 2 , a second duct 3 and a third duct 4 , where the first duct 2 forms an inlet path 2 through which the air from the compressor passes, the second duct 3 and the third duct 4 Two exit paths 3 and 4 are defined here. The valve 1 receives instructions from the processor 103 which are implemented in the form of movements of valve members, which will be described below. The outlet path 3 , called the cooled path, is connected to a heat exchanger or cooler 5 , while the outlet path 4 , called the bypass path or uncooled path, ...

Abstract

The invention relates to a three-way valve (1), in particular intended for use in an air intake circuit of a motor vehicle, comprising: delimiting a first duct (2), a second duct (3) and a third duct (4) the body (200), the duct opening into the shared interior space (201); the first petal (21), movable to block the first duct, the first petal (20), movable to Selectively blocking the second or third conduit, a single actuator is arranged to selectively move at least one of the first and second petals.

Description

technical field [0001] The invention relates to a valve intended for use, for example, in the intake circuit of a heat engine, and in particular of a diesel engine. Background technique [0002] Such an intake circuit comprises in a known manner a cooled path and an uncooled path, also called a bypass path, the function of which is to diverge the cooled path. These two paths are controlled by one or more valves which, on the one hand, allow the metering of the amount of air introduced into the motor and, on the other hand, the selection of the path taken by the intake air to be cooled or not to be cooled. These two paths can then join each other at the inlet of the heat engine. [0003] A first known type of arrangement of the intake circuit described in FR2900455 consists of a three-way valve comprising two separate valve members mounted in parallel, each valve member allowing control of the The flow of air flowing in the path. For safety reasons and to prevent the motor...
