ABSTRACT:
A puck retaining recess in a plunger of a solenoid valve is formed with a puck retaining lip that is fixed or unified with the plunger. The puck is then radially compressed to fit through a central opening of the retainer lip, and once the puck is pushed past the retainer lip, it is allowed to radially expand within the recess where the puck is retained between a bottom of the recess and the retainer lip. This eliminates many problems that previously occurred with separable retainer lips pressed into position to hold a puck after its insertion into a plunger recess.
