Valve controlling device for vehicle`s internal combustion engine, has annular support body with functional segments of bushing, which are situated with respect to contour of projection plane of passage in fluid flow direction

摘要

#CMT# #/CMT# The device has a valve body (3) with a central tubular formation (11) providing a passage (11`) to receive a control axle (6). The body is extended at ends of the formation via an end fitting constituting hubs (12, 12`). The end fitting assures cooperation of free assembly in rotation and with blocking of the body in a bearing of an annular support body (4). The body (4) has functional segments (7`, 7``) of a bushing (7) situated with respect to a contour of a projection plane of a passage in the fluid flow direction. The hubs have passages contiguous with the passage of the formation. #CMT#USE : #/CMT# Valve controlling device for being used in air intake collector or splitter mounted on an internal combustion engine of a vehicle (claimed) for controlling flow of fluid e.g. gas, at the level of opening or at exit of conduit. #CMT#ADVANTAGE : #/CMT# The annular support body has functional segments of the bushing, which are situated with respect to the contour of projection plane of the passage in the fluid flow direction, thus limiting wear and damage of bushing and perturbation of flow of fluid passing the control device in open position of the valve body. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of a valve control device. 3 : Valve body 4 : Annular support body 5` : Bearing body 5`` : Functional elements 6 : Control axle 7 : Bushing 7`, 7`` : Functional segments 11 : Central tubular formation 11` : Passage 12, 12` : Hubs.
