Device for cleaning air lines

Abstract

A pneumatic pressure line cleaning assembly for clearing the pneumatic lines of a pressure gauge, specifically a speedometer for a power boat, is attached to a cut tube of the pneumatic line between the pressure gauge and the air intake opening with a second port of a three-port valve being connected in flow communication with the pressure gauge and a third port opening of the three-port valve being in flow communication with the pressure intake opening. The first port of the three-port valve is in flow communication with an air compressor. In normal operating conditions, ports two and three of the three-port valve are in flow communication so that the pressure gauge pneumatic line is in flow communication with the pressure intake opening and in a second position, the three-port valve is positioned so that the third-port is in flow communication with the first port. In the second position, the air compressor is actuated to provide pressurized bursts of air in a direction towards the air intake opening.
