Abstract: A uniformly preset spring force pre-load among a number of identical solenoid actuated valve assemblies (28) by uniquely adjusting the spring pocket length (L) of each respective plunger (12) to accommodate a respective spring (20) which is uniquely mated thereto. This adjustment is accomplished using a two-component plunger (12) consisting of a plunger body (14) having a central bore (22) and a rod (18) slidably located within the central bore. The rod (18) is press-fit into the central bore (22), and the spring pocket includes a portion of the central bore unoccupied by the rod. By pressing the rod (18) a selected distance into the central bore (22), a precisely set spring pocket is obtained which is uniquely correct for a selected spring (20), in that the selected spring is compressed to a precisely preset spring force pre-load.

Abstract: A control-by-wire control system comprising a plurality of control device(s), each control device is responsive to, and configured to receive a control signal. Also included in the control-by-wire control system is a plurality of sensors wherein certain sensors are coupled to particular control devices. The sensors, each sense a parameter of the system and generate various sensor signals in response. A plurality of control modules is also included in control-by-wire control system. Each control module is interfaced to at least one of the control devices and is adapted to receive at least one or more sensor signals. The control modules also generate control signals for communication to the control devices. A communication interface of at least two communication networks provides communications among various control modules.
