Abstract
A valve body has a bore in an exhaust flow path extending from a supply port to an exhaust port. The bore is bounded by a cylindrical inner surface with a stationary throttling corner. A cylindrical outer surface of a throttling member has a movable throttling corner. The movable throttling corner on the throttling member is sized to constrict the exhaust flow path upon moving coaxially toward the stationary throttling corner on the valve body. The movable throttling corner and the cylindrical outer surface are together sized to close the exhaust flow path upon moving coaxially past the stationary throttling corner and into the bore.
