ABSTRACT:
This invention relates to an exhaust valve to remove air under pressure from the sand magazine of a core or molding machine apparatus which reduces the noise of the exhaust and which includes a housing member for a reciprocable piston that controls an exhaust port of substantial size in such housing and a screen housing projecting through the wall of the sand magazine with a screen mounted in the screen housing to filter incoming air through a relatively large inlet port.
