  • Pneumatically activated drain valve for compressed air
    Patent number: 4987919
    Abstract: A drain valve for a compressed air tank is pneumatically activated by the residual air which is released from an air compressor when the air compressor comes to a stop after an active cycle. The invention allows for consistent and reliable draining of condensation from a compressed air tank. The energy of the residual air released is used to operate the valve. Under favorable conditions, the valve is operated at a frequency proportional to the rate of moisture condensation.
