It also includes any storage reservoirs for the operating medium and the return lines, but not the vehicle's engine (except for the purposes of item 4.1.3) or its drive to the energy source; 1.3.4.1. Energy source means that part of the energy supply which provides the energy in the required form e.g. hydraulic pump, air compressor; 1.3.4.2. Energy reservoir means that part of the energy supply in which the energy provided by the energy source is stored; 1.3.4.3. Storage reservoir means that part of the energy supply in which the operating medium is stored at or near to the atmospheric pressure. 1.4. Steering para ...[+++]meters 1.4.1. Steering control effort means the force applied to the steering control in order to steer the vehicle; 1.4.2. Steering time means the period of time from the beginning of the movement of the steering control to the moment at which the steered wheels have reached a specific steering angle; 1.4.3. Steering angle means the angle between the projection of a longitudinal axis of the vehicle and the line of intersection of the wheelplane (being the central plane of the tyre, normal to the spin axis of the wheel) and the road surface; 1.4.4. Steering forces mean all the forces operating in the steering transmission; 1.4.5 Mean steering ratio means the ratio of the angular displacement of the steering control to the mean of the swept steering angle of the steered wheels for a full lock-to-lock turn; 1.4.6. Turning circle means the circle within which are located the projections onto the ground plane of all the points of the vehicle, excluding the external mirrors and the front direction indicators, when the vehicle is driven in a circle; 1.4.7. Nominal radius of steering control means in the case of a steering wheel the shortest dimension from its centre of rotation to the outer edge of the rim. In the case of any other form of control, it means the distance between its centre of rotation and the point at which the steering effort is applied. ...

Manually operated hydraulic steering gear is an installation in which the rudder is driven by a pump which in its turn is driven solely by a manually operated steering wheel (steering wheel pump).

Where the main steering gear is hydraulically operated while the secondary steering is a manually operated hydraulic system, the piping of the manually operated system must be separate from that of the main installation.

3.07.2. Where the sole steering installation is a manually operated hydraulic system it is not to be regarded as powered steering gear in the sense of 3.04, requiring an independent secondary steering system, provided that: - the dimensioning, construction and layout of the piping precludes deterioration through mechanical action or fire, and

In the case of hydraulic installations, the nominal rating of the drive motor must be such as to ensure maximum output from the pump at maximum pressure in the installation (safety valve setting) having regard to the efficiency of the pump.

The main items in the project are the drilling of 600 productive boreholes equipped with handpumps, the fitting out of 30 perennial springs, and the organization of villagers to enable them to take on the financial responsibility for installation maintenance as a means of provinding the project with long-term viability.
