As you start, pressure is generated with either a master cylinder (through model MVH200) or a rotary pump (MVH306 and larger).

Travel direction is determined by the relative position of the two eccentric weights to each other.

Forward and reverse direction is changed by means of switching the pressurized oil between servo pistons located on the eccentric case. The servo pistons change the position of the eccentric weights.

The hydraulic circuit is designed to return pressurized oil to the tank while the plate is in the neutral travel position. This allows for full compaction force while in neutral.
