    , ! hydraulic jac& is a de$ice used to lift hea$y loads, The de$iceitself is light compact and portale ut is capale of e.ertinggreat force,

    , The de$ice pushes li/uid against a piston0 pressure is uilt in the

     jac&1s container, The jac& is ased on Pascal1s la' that thepressure of a li/uid in a container is the same at all point

    S' S6 2e sho'ed that the force e.erted y a li/uid on the ase of a $essel ise/ual to the 'eight of a li/uid column e.tending from the ase to the free surface,

    L'$rd' d$ V in his research in the late *3))s 4rst demonstrated the use of ascre' jac& for lifting loads, %eonardo5s design used a threaded 'orm gear supported on

    earings that rotated y the turning of a 'orm shaft to dri$e a lifting scre' to mo$e the

    load,

     ,'!" "'r"6 in his research recognised the need for precision had ecome asimportant in industry as the pro$ision of po'er,

    -r$# Hr/6 in his e.periment during the early *66)s in Coaticoo& designed a lifting jac&, %i&e da 7inci5s jac& it 'as technological inno$ation ecause it 'as ased on the

    principle of the all earing for supporting a load and transferred rotary motion through

    gearing and a scre' into linear motion for mo$ing the load,

    Ar"ur %'r N'r'6 H spotted the potential for 8leeper5s design and in *66+hired the young man and the 9Norton5 jac& 'as orn, O$er the coming years the famous

    9Norton5 jac&s 'ere manufactured at plants in :oston Coaticoo& and Moline Illinois,

    . As a vehicles undergo a tyre failure than first we will turn the five-way valve handletoward the failed tyre jack.

    . Now when we push the brake pedal than the fluid from the master cylinder will pass

    through the five-way valve and move in the direction of the handle of valve ,this willmake the piston in the hydraulic cylinder(jack) to move down and the tyre start lifting.

    . he non return check valve is manually opened after replacing the tyre so that thefluid to go back into the master cylinder and the tyre start coming down to its initial

     position.

    #ydraulic cylinders get their power 

     from pressuri$ed hydraulic fluid ,

     which is typically oil.

     he hydraulic cylinder consists of a

     cylinder barrel, in which a piston

     connected to a piston rod moves

     back and forth..

     he piston has sliding rings and seals.
