Abstract
A vacuum assembly includes a housing and a movable assembly positioned within the housing. Movement of the movable assembly relative to the housing creates a low pressure area. A fluid flow conduit is in fluid communication with the low pressure area. A leakage valve is disposed within the fluid flow conduit and is movable between a first position and a second position to restrict a flow through the fluid flow conduit upon detection of an undesired fluid within the low pressure area.
