Abstract
A shutter for closing openings with pivotal shutter elements, the rotational axes of which are arranged parallel to each other. Better sealing is achieved in that the shutter elements consist of at least two wings that are solidly joined together and arranged almost parallel to each other. The wings of the shutter elements are oriented substantially parallel to an imaginary plane of the opening, thus closing it on both sides, in a first position and substantially normal to the plane of the opening, thus clearing said opening, in a second position.

A shutter assembly for use with an opening leading to an internal combustion engine comprising pivotal shutter elements having rotational axes which are arranged parallel to each other, wherein each of said shutter elements comprises at least first and second wings solidly joined together and arranged almost parallel to each other, in a first position of said shutter elements said first and second wings are oriented substantially parallel to an imaginary plane defined by said opening, said first wings of said shutter elements being adjacent one another to form a first wing layer that closes said opening, and said second wings of said shutter elements being adjacent one another to form a second wing layer that also closes said opening, a closed air space being thus formed between said first and second wing layer, and in a second position of said shutter elements said first and second wings are substantially normal to said imaginary plane, thus clearing said opening.
An internal combustion engine with a radiator through which air is flowing, comprising at least one shutter assembly comprising pivotal shutter elements having rotational axes which are arranged parallel to each other, wherein each of said shutter elements comprises at least first and second wings solidly joined together and arranged almost parallel to each other, in a first position of said shutter elements said first and second wings are oriented substantially parallel to an imaginary plane defined by said opening, said first wings of said shutter elements being adjacent one another to form a first wing layer that closes said opening, and said second wings of said shutter elements being adjacent one another to form a second wing layer that also closes said opening, a closed air space being thus formed between said first and second wing layer, and in a second position of said shutter elements said first and second wings are substantially normal to said imaginary plane, thus clearing said opening.
A shutter assembly for use with an opening leading to an internal combustion engine comprising pivotal shutter elements having rotational axes which are arranged parallel to each other, wherein each of said shutter elements comprises at least first and second wings solidly joined together and arranged almost parallel to each other, in a first position of said shutter elements said first and second wings are oriented substantially parallel to an imaginary plane defined by said opening, said first wings of said shutter elements being adjacent one another to form a first wing layer that closes said opening, and said second wings of said shutter elements being adjacent one another to form a second wing layer that also closes said opening, a closed air space being thus formed between said first and second wing layer, and in a second position of said shutter elements said first and second wings are substantially normal to said imaginary plane, thus clearing said opening, wherein in said second position, said first wing of one shutter element is situated adjacent said second wing of a neighboring shutter element.
