Claim:
An assembly for a non-sliding valve that includes a solenoid armature, a support spring holding the armature for movement without sliding contact with any valve surface, a puck carried by the armature, and a valve seat disposed to engage the puck, the improvement comprising: a shell machined to form an outer spring reference surface engaging an outer perimeter of the spring; the shell being machined to form a seat reference surface spaced from the outer spring reference surface to engage an outer perimeter of the seat; the armature being machined to form a reference surface engaged by an inner perimeter of the spring; and engagement of the outer perimeter of the seat against the seat reference surface flexes the spring, while urging the puck against an inner rim of the seat, and moves the armature to urge the inner and outer perimeters of the spring respectively against the inner and outer spring reference surfaces.
