Solenoid Operation:

An interesting aspect of solenoid operation is that it can HOLD a force with a small fraction of the current required to STROKE  the same force through the length of its travel. Once the armature bottoms-out it's capable of holding many times the force needed to initially engage the pinion gear.  Designers reasond correctly that the total electrical energy and size of solenoid required to operated a starter be reduced along with a small change in design.

Deceleration valve:

1 - The hydraulic circuit with acceleration deceleration valve is a simple and cost-effective alternative for controlling the acceleration and deceleration of hydraulic actuator while starting and stopping. The circuit can be used for getting a jerk free motion of any hydraulic actuator. Since it is compact and low cost, it finds  great application  in hydraulic material handling equipment where expensive proportional valves are used just to control the initial acceleration and final deceleration of the actuator.

2 - The CDUS carburettor is equipped with a choke disc controlled by a manual choke control, a deceleration valve (overrun braking valve), which reduces exhaust emissions during overrun braking and gear-changing and a device which allows the idling mixture to bypass the throttle.

Sequencing Actuators:

The Low/High Sequence feature is used when proportional sequencing multiple dampers or valves.  The low sequence actuator rotates proportionally through its full travel during the first 50% of the output command.  If the demand increases, the high sequence actuator rotates proportionally through its full travel as the input command increases from 50% to 100%.

Obliquity Angle:

Angle of Obliquity: Angle between vehicle body axis and target normal at point of impact (positive is clockwise).
