ABSTRACT:
The invention is in a priority valve that includes a housing arranged for in-line mounting between a conventional turbocharging unit of an internal combustion engine, an intercooler and an engine intake manifold to receive a charge air flow, and to either direct that flow directly to an engine intake manifold or to the intercooler, with the flow to pass from the intercooler back through the priority valve and then to the engine intake manifold. The priority valve includes a valve member that is preferably a cylinder and is journaled in the housing to turn between a first position, where the charge air flow, that is received from the turbocharger unit, is directed to the engine intake manifold, and a second position where the received charge air flow is first directed to the intercooler, with that flow passed back to the priority valve from the intercooler and is then passed from the priority valve into the line to the engine intake manifold. The invention may include a solenoid, or the like, connected to operate the cylindrical valve member to move it between its first and second positions, which solenoid, or the like, is operated responsive to a sensing of a set temperature of the charge air flow, by a sensing of a set pressure or above of the charge air flow at the engine inlet manifold, or on command as from a computer, or the like. The cylindrical valve member to have surfaces formed therein that, when the valve member is in its first or second positions, receives the charge air flows thereagainst and redirected each flow out of an appropriate port to create a minimum turbulence in the charge air flow.
