A pressure sprayer is pressurized automatically with movement of the sprayer and maintains adequate pressure during non-movement to allow the ejection of an amount of liquid before needing re-pressurization. The pressure sprayer includes wheels that allow the pressure sprayer to be mobile. A cam is attached to the axle of the wheels which rotates with the rotation of the axle/wheels. A pressure pump is associated with the cam such that movement of the cam causes the pressure pump to pump liquid from a holding tank to an accumulator or directly to a spray wand in communication with the pump. The liquid may be sprayed (ejected) from the accumulator during both movement (pumping) and non-movement (no pumping) of the sprayer, while the liquid may be directly sprayed from the holding tank only during movement (pumping) thereof. Thus, as the wheels rotate due to moving the pressure sprayer, the cam causes movement of the pressure pump to fill the accumulator with the liquid under pressure. The pressure pump is adapted to obtain liquid from the holding tank and provide that liquid to the pressure accumulator. A relief valve is provided to relieve the buildup of pressure during movement of the wheels when no spraying is taking place.
