Abstract
Air bleeding apparatus for an exhaust emission control system comprising three plates joined face to face. The first plate has a plurality of grooves each communicating at one end with a vacuum source and at the other end with a vacuum actuator for an ignition timing control system or an exhaust gas recirculation control valve. The second plate has a plurality of orifices communicating with the grooves, respectively; the third end plate has a vent hole therethrough and grooves diverging from the vent hole and respectively communicating with the orifices. The second plate is joined abuttingly to and between the first and third plates whereby the grooves form conduits therewith, whereby the conduits of the first plate communicate with the vent hole of the third plate through the respective orifices of the second plate and the respective conduits of the third plate. The characteristics of the apparatus may be varied by changing the second plate to one having different orifices.
