$(25\%$ of theory mark$)$

You are designing a hydraulic system to convert the box of a $1-$ton truck into a dump box.

Draw a schematic of how the system will work.

You will use:

$-$A $3$ position, $4$ way tandem center vaive. $(3$ marks$)$

$-$A double acting, unbalanced cylinder. $(3$ marks$)$

$-$Relief valve $($Direct acting or pilot operated$).(4$ marks, $3$ marks given for the proper use of a direct

acting and $4$ marks given for the proper use of a pilot operated relief valve$)$

$-$Fixed displacement pump. $(3$ marks$)$

$-$Reservoir. $(3$ marks$)$

$-$Filter, return side. $(2$ marks$)$

This schematic must show the proper and complete flow of fluid in order to receive full marks.

Do schematic on drafting paper and hand in$.$

Must be legible
