ABSTRACT:
A plunger for a control valve having a head with a tab located in a slot in a hub member and a cylindrical body with a threaded projection connected to the head. Rotation of the cylindrical body moves the head in the slot to establish the space relationship between a reaction disc and a face on the head. The space relationship sets the distance that a reaction disc must be extruded by a reaction force before opposing an input force. The delay in opposing an input force assures that a predetermined force is developed and immediately supplied to a master cylinder.
