Controllable ejector-flap arrangement for the ejector elbows of choppers or impeller blowers

摘要

In the controllable ejector-flap arrangement for the ejector elbows of choppers or impeller blowers, which have one or more flaps with receiving orifices for a generally horizontal rotary axle, by means of which they are connected to one another and to the ejector elbow, the receiving orifices are designed as long holes arranged obliquely relative to the longitudinal direction of the flaps, so that the otherwise necessary gap between the flaps is avoided. <IMAGE>
