ABSTRACT OF THE DISCLOSURE A garden sprayer for dispensing pressurized liquids has a pressure vessel mounted within a liquid reservoir container. The pressure vessel carries a diaphragm pump which is detachable as a complete unit and which extends from the container for connection to a pivoted actuating lever that is fulcrumed on the container. The diaphragm, which is directly driven by the pivoted lever, is guided in position and orientation by a guide piston fixed to the diaphragm and slidably guided within the pumping chamber. A pair of input and output check valves, mounted at the end of the pump, permit liquid from the container to be drawn into the pumping chamber and to be forced from the pumping chamber into the pressure vessel. A manually controlled valve on a spray nozzle, which is connected to the pressure vessel, controls pressurized discharge of liquid.
