Abstract:

A device for separating air entrained in, and associated with, liquid being pumped. The device comprises a tank member communicating with the intake chamber of a liquid pump and with a vacuum pump. Disposed within the tank member is an open container member having a liquid conduit connected with the intake chamber of the liquid pump. Integrally connected with the top of the tank member is a baffle member which extends downwardly into the container member in such manner that liquid flowing into the container from the tank member flows downwardly between the inner surface of the container and the outer surface of the baffle. Disposed within the container are means responsive to the level of the liquid within the container member. A first valve member responsive to the movement of the liquid level is provided for the discharge of gases into a gas exhaust chamber and out of the device through the vacuum pump. A second valve connected with the atmosphere is disposed in the exhaust chamber and operatively connected to the first valve member in such manner that said second valve is open to the flow of air from the atmosphere when the first valve is closed.
