Abstract
A valve is installed in an opening provided in a thin wall of an air intake pipe, which supplies combustion air from a flow control device to a cylinder of an internal combustion engine, to relieve excess pressure in the pipe. The valve includes a socket connected to a segment of the air intake pipe, and an elastomer, umbrella valve member is supported in the socket to normally cover the opening in the pipe and to undergo deformation when the pressure in the pipe reaches a predetermined value to uncover the opening and to connect the interior of the pipe to the ambient atmosphere.
