Abstract

A fluid switching device ( 1 ), in particular for a valve having at least three ports, the device ( 1 ) comprising: a flap ( 10 ) capable of pivoting between a first position in which it blocks a first port ( 9 ) and a second position in which it blocks a second port ( 11 ), an actuating member ( 12, 13, 40 ) for actuating the flap ( 10 ), capable of moving the flap ( 10 ) from one blocking position to the other, the device ( 1 ) comprising an interface part ( 18, 25 ) capable of interacting with the actuating member ( 12, 13, 40 ), the device being configured in such a way that this interaction selectively allows the flap ( 10 ) to be moved by the actuating member ( 12, 13, 40 ) and selectively allows the flap ( 10 ) to be held in position, the actuating member ( 12, 13, 40 ) comprising a mobile part ( 12, 13 ) and defining a guide path guiding the interface part ( 18, 25 ) when the flap ( 10 ) moves, due to the movement of the mobile part ( 12, 13 ).

First claim

1 . A fluid switching device ( 1 ) in particular for a valve having at least 3 ports, the device comprising:
a flap pivotable between a first blocking position of a first port and a second blocking position of a second port; an actuating member of the flap capable of moving the flap from one to the other of the blocking positions; and an interface part capable of interacting with the actuating member, the device being configured so that this interaction selectively moves the flap by the actuating member and selectively holds the flap in position, wherein the actuating member comprises a mobile part that defines a guide path guiding the interface upon movement of the flap by movement of the mobile part.

2 . The switching device according to claim 1 , wherein the guide path is formed by a guide housing arranged inside the mobile part, said guide housing having two opposing lateral edges against which the interface part selectively comes in contact when the flap moves from one to the other of the blocking positions.

3 . The switching device according to claim 2 , wherein the guide housing comprises two segments having a common end.

4 . The switching device according to claim 3 , wherein the flap is in an intermediate position in which the first and the second ports are open when the interface part is received at the common end of the two segments of the guide housing, the flap switching to one or the other of the blocking positions when the interface part moves in one of said segments towards an end opposite to the common end.

5 . The device according to claim 3 , wherein the device is located at each end opposite to the common end of a segment, the lateral edge of the segment nearest the other segment extending radially beyond the other lateral edge of said segment.

6 . The switching device according to claim 1 , wherein the actuating member further defines a holding path of the interface part to hold the flap in the one or the other of the blocking positions.

7 . The switching device according to claim 6 , wherein the holding path has a lateral edge defined by a portion of the outer periphery of said mobile part.

8 . The switching device according to claim 6 , wherein the holding path is a housing arranged inside said mobile part on part of the periphery of said mobile part.

9 . The switching device according to claim 7 , wherein the holding path and the guide path communicate through at least one common lateral edge.

10 . The switching device according to claim 1 , wherein the actuating member has a spring which is compressed to the maximum when the flap is in an intermediate position of opening of the first and second paths.

11 . The switching device according to claim 10 , wherein the spring is configured to hold the flap in blocking position.

12 . The switching device of claim 1 , wherein the mobile part is configured so that the guide path is in contact with the interface part only on a limited angular sector during rotation of the mobile part.

13 . The switching device of claim 1 , wherein the flap and the interface part are separate parts rigidly coupled together.

14 . An engine control valve comprising a switching device according to claim 1 .

15 . The engine control valve according to claim 14 , further comprising one input port and two output ports, the flap being pivotable to move from a blocking position of one output port to a blocking position of the other output port.

16 . The engine control valve according to claim 14 , further comprising two input ports and one output port, the flap being pivotable to move from a blocking position of an input port to a blocking position of the other input port.
