摘要：A tubular member is adapted to communicate with an intake manifold andcombustion gas conduit of a combustion engine. A housing of the valve has an interiorspace and a slidable valve member normally extends across and blocks the interior of thetubular member, having a portion extending into the interior space of the housing. Atleast one flexible diaphragm subdivides the interior space into two chambers and is fixedto the portion of the valve member. One of the chambers communicates with theatmosphere. A first and a second conduit connect the other chamber with the manifoldand with the atmosphere, respectively. An electromagnetic valve is operative foralternately connecting the other chamber with the first and with the second conduit,respectively.
