    摘要: The present invention provides a system that automatically purges contaminants from an air pressure tank when the emergency brakes of a vehicle are set. In one preferred embodiment, the system comprises a valve comprising an input port, an exhaust port, and a control port. The input port is in fluid connection with a drain on the pressurized air tank, and the control port is in fluid connection with an emergency brake line of the vehicle. When the emergency brakes are engaged, the valve is open such that the input port and the exhaust port are in fluid connection operable for air and contaminants from the pressurized air tank to be expelled from the pressurized air tank through the exhaust port. When the emergency brakes are not engaged, the valve is closed such that the input port and exhaust port are not in fluid connection.

    摘要: A fluid transfer device for transferring fluid between a supply reservoir and a fill reservoir includes a metering reservoir and a manifold that forms at least part of a first channel that is fluidly connected with the metering reservoir. The first channel comprises a first cannula extending from the manifold. The manifold forms at least part of a second channel fluidly connected with the metering reservoir. The second channel comprises a second cannula extending from the manifold. A third channel extends through the manifold and comprises a third cannula having a first end proximate a distal end of the first cannula and a second end proximate a distal end of the second cannula. A first check valve is disposed within the first channel and a second check valve is disposed within the second channel.
