Abstract
An irregularity that might otherwise be present in the flow characteristic of the system is cured by damping the motion of the armature of the CPS valve in two ways. One way comprises incorporating a 'step' into the confronting faces of the armature and stator at their interface across the air gap. The other way comprises guiding the armature motion by means of a brass tube with sufficiently small running clearance such that pneumatic damping occurs.
