MAGNETICALLY LATCHING VALVE FOR FUEL VAPOR MANAGEMENT SYSTEMS AND SYSTEMS INCORPORATING SAME
Magnetic latching valves for a vehicle engine have a housing having a first port and a second port in controlled fluid communication with one another. The housing encloses a linearly translatable armature seated within a solenoid and connected to a primary poppet valve. The armature is movable between an open position and a closed position, respectively, after a pulse of voltage to the solenoid and is in an unpowered state thereafter. A permanent magnet is fixedly seated in a position to magnetically latch the armature in a fully open position. A spring is seated to bias the primary poppet valve closed when the armature is in the closed position. The spring has a spring rate that mechanically relieves pressure by opening the primary poppet valve a distance less than the fully open position when the spring force is exceeded, thereby also allowing flow in the primary flow direction.

SOLENOID ACTIVATED VACUUM PUMP FOR AN ENGINE SYSTEM AND SYSTEM HAVING SAME
Start-stop engine systems for a turbocharged engine have a bypass with fluid flow from upstream of the compressor or downstream of the compressor to a position between the throttle and the engine, or from between the compressor and throttle to a position upstream of the compressor with a Venturi device in the bypass. A device requiring vacuum is in fluid communication with a suction port of the Venturi device. An electronic vacuum pump is added that is in fluid communication with the device requiring vacuum or with the Venturi device. The electronic vacuum pump is operated during a stop condition of the start-stop engine to replace the vacuum generated by the Venturi device or to provide a pressure drop across the Venturi device so the Venturi device continues to generate vacuum for the device requiring vacuum.

An engine system including a first flowpath between a first component and a second component where a first aspirator forms a portion of the first flowpath, and a second flowpath between the first component and the second component, where a second aspirator forms a portion of the second flowpath. A shut-off valve forms a portion of the second flowpath. The first aspirator and the second aspirator each have a suction inlet, and the suction inlet of the first aspirator is in fluid communication with the suction inlet of the second aspirator.
A pneumatically actuated vacuum pump is disclosed, and includes a body defining a converging motive section, a diverging discharge section, at least one suction port, and a Venturi gap. The Venturi gap is located between an outlet end of the converging motive section and an inlet end of the diverging discharge section. The pneumatically actuated vacuum pump also includes a first check valve fluidly connected to the Venturi gap and the suction port. The pneumatically actuated vacuum pump further includes at least one second gap located in the diverging discharge section of the body downstream of the Venturi gap. A second check valve is fluidly connected to the second gap.
