Title:
An engine intake amount control device
Document Type and Number:
Japanese Patent JP5950203
Kind Code:
B2
Abstract:
In an engine air intake control device, a control interior face (8a) is formed on the interior face of a valve guide hole, a measuring hole to the control interior face (8a) is opened, and a control exterior face (8b) is formed on the exterior face of a control valve to slide in contact with the control interior face (8a). A first pressing section (35a) of a rotational stop means (26), between a control valve and a slide piece, presses the slide piece so that the control exterior face (8b) is brought in contact with the control interior face (8a) by pressing a first pressure receiver (36a) when operating a screw shaft (29) in forward, and a second pressing section (35b) presses the slide piece so that the control exterior face (8b) is brought in contact with the control interior face (8a) by pressing a second pressure receiver (36b) when operating the screw shaft (29) in reverse. Thus, a gap can be prevented by always having the interior face of the valve guide hole in which the measuring hole is opened and the exterior face of the control vale in contact, with manufacturing errors or assembly errors having no substantial impact.
