Abstract

An assembly and process for draining fluid leaks from a pump housing is disclosed. The pump housing includes an internal mounting cavity, a valve installed in the mounting cavity and at least one housing passage extending to an exterior surface of the pump housing. A valve passage is formed through a wall of the valve. An interior fluid seal is installed on an interior surface of the valve forming a seal between the valve interior surface and a first surface of the mounting cavity. An exterior fluid seal is installed on an exterior surface of the valve that forms a seal between the valve exterior surface and a second surface of the mounting cavity. An inner leak path is created through the interior fluid seal to the valve passage. The valve passage collects fluid leaking in the inner leak path. An outer leak path is created through the exterior fluid seal. The outer leak path in fluid communication with the valve passage and with the housing passage. Fluid leaking in the exterior fluid seal and fluid contained in the valve passage is drained through the housing passage to the exterior of the pump housing.
