Valve, in particular for an internal combustion engine

Abstract

A valve ( 1 ), in particular for a combustion engine, comprising:—a body ( 2 ) in which the following are provided: a housing ( 8 ) in which at least one bearing is arranged, and a conduit ( 3 ) designed to be traversed by a fluid, and—a shutter ( 5 ) mounted pivoting in the body ( 2 ) by a pin ( 7 ) received with radial clearance in the bearing, the shutter ( 5 ) pivoting between:—an open position, and—a closed position in which it comes into contact with the body ( 2 ) via a first contact area of the shutter located on a first side of the pin ( 7 ) and via a second contact area of the shutter located on a second side of the pin ( 7 ) opposite said first side, the switching of the shutter ( 5 ) from the open position to the closed position being accompanied by a radial movement of the pin ( 7 ) in the bearing.

1 . A valve for an internal combustion engine, comprising:
 a body including:
 a housing in which is disposed at least one bearing and a duct adapted to have a fluid pass through it, and 
 a shutter mounted to pivot in the body by means of a pin received with radial play in the bearing, the shutter ( 5 ) pivoting between:
 an open position, and 
 a closed position in which the shutter comes into contact with the body in a first contact area of the shutter on a first side of the pin and in a second contact area of the shutter on a second side of the pin opposite said first side, 
 
 the passage of the shutter from the open position to the closed position being accompanied by radial movement of the pin in the bearing. 
   
     
     
         2 . The valve as claimed in  claim 1 , wherein the valve lacks any flexible element disposed between the shutter and the body when the shutter is in the closed position. 
     
     
         3 . The valve as claimed in  claim 1 , wherein the shutter and the pin are connected by a support extending along at least a portion of the pin. 
     
     
         4 . The valve as claimed in  claim 1 , the body having a sealing plane of the body coming into contact with the first contact area and/or the second contact area of the shutter when the shutter in the closed position and the first contact area and/or the second contact area of the shutter being in a sealing plane of the shutter. 
     
     
         5 . The valve as claimed in  claim 4 , wherein the distance between the center of the housing and the sealing plane of the body is greater than the distance between the center of the pin and the sealing plane of the shutter. 
     
     
         6 . The valve as claimed in  claim 4 , wherein the distance between the center of the housing and the sealing plane of the body is less than the distance between the center of the pin and sealing plane of the shutter. 
     
     
         7 . The valve as claimed in  claim 1 , wherein the first contact area and/or the second contact area of the shutter form a line contact with the body when the shutter is in the closed position. 
     
     
         8 . The valve as claimed in  claim 7 , wherein the shutter has a rectangular shape and the first contact area and the second contact area being on opposite sides of the shutter. 
     
     
         9 . The valve as claimed in  claim 7 , wherein only the first contact area of the shutter is in the sealing plane of the shutter, the second contact area of the shutter being in another plane of the shutter. 
     
     
         10 . The valve as claimed in  claim 9 , the sealing plane of the shutter and said other plane of the shutter being on opposite faces of the shutter. 
     
     
         11 . The valve as claimed in  claim 1 , wherein the first contact area and/or the second contact area of the shutter form a plane contact with the sealing plane of the body when the shutter is in the closed position. 
     
     
         12 . The valve according to  claim 11 , wherein the first contact area and the second contact area of the shutter are in the sealing plane of the shutter and each of said contact areas of the shutter contacts the sealing plane of the body when the shutter is in the closed position. 
     
     
         13 . The valve as claimed in  claim 11 , the first contact area of the shutter being on a first part of the shutter and on the upper face of said first part, the second contact area of the shutter being on a second part of the shutter and on the lower face of said second part. 
     
     
         14 . The valve as claimed in  claim 13 , wherein the first part and the second part are rigidly coupled to each other to form the shutter in the sealing plane of the shutter. 
     
     
         15 . The valve as claimed in  claim 13 , wherein the length of the second part of the shutter measured along the pin is less than the length of the first part of the shutter measured along the pin. 
     
     
         16 . The valve as claimed in  claim 4 , the sealing plane of the shutter being a plane other than a plane intersecting the pin. 
     
     
         17 . The valve as claimed in  claim 1 , wherein the valve is a three-port valve, and each of the open and closed positions comprise an extreme position for the pivoting of the shutter.
