A ventilation valve () for ventilation of a space for keeping animals or plants includes an opening-defining circumferential framework () for mounting in a wall of that space, and a movable panel (). The panel () is movably attached to the framework () for relative movement between a fully closed position, in which substantially no air can pass between the framework and the panel, and a fully open position, in which substantially the complete opening is available for passage of air. A profiled edge on the framework provides a non-linear relation between a passage opening and an opening position of the panel (). Also provided is a system for ventilating the space, having at least a single ventilation valve, and for periodically determining parameters of inside air in the space, and adjusting the opening position of the valve based on the parameters.

Ventilation valve, method and system for ventilation of a space for animals or plants

A feeding station for farm animals (), as in particular for pigs, provided with a first reservoir () for a first animal food component, a first conveyor pipe () connected to the first reservoir (), with a first conveyor screw () extending internally of the first conveyor pipe (), and a mouthpiece () for reception in the mouth of an animal (). A first end of the first conveyor screw () is coupled adjacent to the first reservoir () to a rotatable first drive () and a second end of the first conveyor screw () ends shortly before the mouthpiece (). The feeding station () is further provided with at least a second reservoir () for a second animal food component, a second conveyor pipe () connected to the second reservoir with a second conveyor screw () extending internally of the second conveyor pipe (). A first end of the second conveyor screw () is coupled adjacent to the second reservoir () to a second drive () which is rotatable independently of the first drive (). The second conveyor pipe () is joined together with the first conveyor pipe () adjacent to a second end of the second conveyor screw (). The first and second drives () are operable by a control unit () in accordance with a desired mixing ratio of the first and second animal food components.
