Exhaust gas recirculation valve (10) arranged in an exhaust gas recirculation line (12) comprises a valve element (16) arranged on a valve seat (14) so that it tilts, rotates or pivots about an axis perpendicular to the flow direction. In the closed state ...

A short-stroke solenoid-actuated valve assembly (10) modified to minimize mechanical clatter. The valve has a valve seat (20) formed of compressed powdered metal to reduce the intensity and sharpness of sound resulting from closing contact with the valve h...

A system for containing leakage along a pintle shaft (22') in a pintle-type gas control valve, such as an exhaust gas recirculation valve for an internal combustion engine or a reformate diverter valve for a fuel cell, comprising a novel seal element and m...

The present invention is directed to an annular metal-bristled brush (72) for cleaning the pintle shaft (22) of a pintle valve, such as an exhaust gas recirculation valve for an internal combustion engine, to prevent coking and failure of the valve. The br...

An improved electric solenoid for providing linear mechanical actuation. The outer polepiece of the solenoid is provided with an axial, self-lubricated, non-magnetic bearing for closely supporting and centering an actuating shaft extending coaxially from t...

A metering subassembly for use with a modular EGR valve 40 includes a metering subassembly 10 having an elongate metering shaft 14. A flanged end 24 of the metering shaft is disposed a predetermined distance above a top surface 30 of the metering subassemb...

A shield 56 for a gas management pintle valve 10, such as an exhaust gas recirculation valve for an internal combustion engine, for mitigating leakage of gas and moisture along the valve pintle 22 into the actuator 30, to prevent corrosion and failure of t...

A pressure balancing metering subassembly 10 for use with a modular actuator 90 of an EGR valve 100 includes a metering base 26 which defines a metering port 80 and a pressure chamber 50. An elongate poppet 18 includes a first end 70 normally disposed in s...
