    Abstract: A backpack sprayer having a tank with a filling opening at the top thereof and a pressure chamber therein is provided with filtering apparatus for preventing particles in the fluid in the tank from entering an inlet port of the pressure chamber when suction generated by a pump causes fluid in the tank to flow through the inlet port into the pressure chamber. Pressurized fluid can flow through an outlet port from the pressure chamber to a nozzle, via a hose in communication with the outlet port. The filtering apparatus is provided by a filter in a frame removably captured in a fixture projecting outwardly from the outside of the pressure chamber on opposite sides of the inlet port. A handle extends from the frame upwardly along the outside of the pressure chamber a sufficient distance to be accessed manually by an operator through the filling opening of the tank.

    Abstract: A backpack sprayer having a tank with a filling opening at the top thereof and a pressure chamber therein is provided with filtering apparatus for preventing particles in the fluid in the tank from entering an inlet port of the pressure chamber located near the bottom of the tank when suction generated by a pump that depends from the bottom of the pressure chamber causes fluid in the tank to flow through the inlet port into the pressure chamber. The fluid pressurized by the pump flows through an outlet port from the pressure chamber for spraying when a valve in the nozzle at the end of a hose communicating with the outlet port is actuated by an operator. The filtering apparatus is provided by a filter in a frame removably captured in a fixture projecting outwardly from the outside of the pressure chamber on opposite sides of the inlet port. A handle extends from the frame upwardly along the outside of the pressure chamber a sufficient distance to be accessed manually when the hand of the operator extends through the filling opening of the tank. The filter prevents particles, such as sediment, in the liquid at the bottom of the tank from flowing into the pressure chamber and pump mechanism thereof thereby preventing clogging of the pump mechanism and interfering with operation of the sprayer. The filter may be manually removed from the fixture for cleaning and then replaced. The need to totally disassemble the sprayer for cleaning is thereby substantially eliminated.
