Power steering case  

The case of the power steering consists of two sections: one includes the cylinder, and another the valve. Main components of section of the cylinder: reducer, lath and cylinder. In section of valves it: block of valves, shaft and rotor. The sleeve is connected with a gear wheel a hairpin, and the valve and a rotor are united in one block. Further the gear wheel and a sleeve are connected with each other with the help of the torsion.

Thus, at the movement of a rotor, valves change the situation, directing liquid from the pump to the cylinder, for the help to rotation of a wheel.

When rotation of a wheel is at a loss, because of leak of liquid or for other reasons (for example, at shutdown of the regime of the amplifier), the rotor and a gear wheel are in direct link and the effort is transmitted directly through the rack mechanism.
