Abstract

A valve for controlling two gas flows, having: two ducts, in each of which a flap is rotatably mounted on a shaft; an electric motor that drives a shaft via a gear unit; and a transmission mechanism which, depending on the movement direction of the first flap, drives the second flap. Each flap is arranged in a separate housing part and the two housing parts are connected to one another.

First claim

The invention claimed is:

1. A valve configured to regulate two gas flows, comprising:
a first housing part composed of a first material having a first duct;
a first shaft arranged in the first housing part;
a first flap mounted rotatably on the first shaft and arranged in the first duct;
a second housing part composed of a second material that is different than the first material connected to the first housing part and having a second duct;
a second shaft arranged in the second housing part;
a second flap mounted rotatably on the second shaft and arranged in the second duct;
an electric motor configured to drive the first shaft; and
a transmission mechanism configured to drive the second flap in a manner dependent on a movement of the first flap,
wherein the first material and the second material are selected from the group consisting of metal and plastic.

2. The valve as claimed in claim 1 , wherein the first housing part and the second housing part are screwed together.

3. The valve as claimed in claim 1 , wherein the first duct and the second duct are arranged at an angle with respect to each other.

4. The valve as claimed in claim 1 , wherein the transmission mechanism comprises a coupling rod and at least one lever.

5. The valve as claimed in claim 3 , wherein the angle is a right angle.

6. The valve as claimed in claim 1 , wherein the electric motor drives the first shaft via a gearing.
