Abstract
A hydraulic power unit for a floor jack that includes an internally-adjustable relief valve that is inaccessible to an operator without removing the power unit from the jack assembly and disassembling the power unit. By placing the relief valve inside of the hydraulic assembly, hidden from operators, the relief valve is less likely to be accidently adjusted when using or servicing the jack.
