    The piston.

    2.What device allows for the cylinder retraction?

    You open the bleed valve, and allow what is behind the piston to bleed back into the reservoir.

    3.What is the reservoir?

    Depends on the construction. Might be in part, the rod side of the cylinder.

    4. What methods are used for cylinder and piston sealing?

    Standard cylinder seals, usually.

    Explain about the relief valve in bottle jack?

    Connected on parallel with the bleed valve, if it has a relief valve.

    Here is a good cutaway... http://i01.i.aliimg.com/img/pb/548/785/486/486785548_989.jpg
