| 1. A vehicle gaseous fluid metering device comprising:
a housing, adapted for routing of gas from an input passage to an output passage;
a valve assembly positioned inside said housing for selectively moving gas from said input passage to said output passage,
said valve assembly including at least one valve seat acting as an opening between said input passage and said output passage,
and at least one valve member operative with said valve seat and acting as a moveable barrier between said input passage and
said output passage, wherein said valve member moves between a closed position and an open position;
a valve shaft connected to said at least one valve member, said valve shaft is operable for moving said at least one valve
member in response to rotation of said valve shaft;
a pin extending from the valve shaft and engaging a ramp portion in said housing; and
an actuator operably coupled to the valve shaft to provide driven translational movement of both the valve shaft and valve
member in both an axial and a rotational direction wherein said at least one valve member radially rotates against said at
least one valve seat prior to moving axially in order to self-clean said at least one valve member and said at least one valve
seat.
