Abstract:
1. Apparatus for testing a cooling system, comprising a valve body adapted for releasable connection to said cooling system, a first port on the valve body adapted for selective releasable connection to a source of positive pressure for pressurizing the cooling system and to a source of negative pressure for de-pressurizing the cooling system, a second port on the valve body adapted for connection to a pressure sensor for monitoring the pressure of fluid in said cooling system, an outlet on the valve body in fluid communication with said first and second ports and adapted for fluid communication with said cooling system when the valve body is connected to said cooling system, a valve passage in the valve body, a valve member movable in the valve passage between open and closed positions, and a flow passage in the valve member such that when said valve member is in said open position the flow passage and said outlet are in fluid communication to permit fluid flow to or from the cooling system via the flow passage and said outlet, and when said valve member is said closed position the flow passage and said outlet are not in fluid communication to block said fluid flow.
