Abstract

The valve member (4) of a bypass valve (2) of a device for regulating the idling of an internal combustion engine is provided, for pressure equalization, with a back-pressure chamber (8) which is in communication via a pressure-equalization connection (9) with the pressure-inlet side of the bypass valve (2). This pressure-equalization connection (9) debouches as close as possible to the narrowest point of the gap between the valve member (4) and the valve seat (7) in the housing (1) of the bypass valve (2).
