Air valve with bleed feature to inhibit icing

The air valve on a reciprocating pneumatic pump bleeds air from the pressurized air chamber into the exhaust port through a hole in the valve cup in order to warm the exhaust port area and prevent ice build up in the area. Such construction is also suited for use in spool valves.
