  • Patent number: 5984199
    Abstract: An improved backpack sprayer, comprising a supply tank, an expandable accumulator, a pump mechanism, an intake valve, a discharge valve, and a spray wand with a nozzle. The supply tank is designed to hold fluids, such as insecticides, herbicides, water sealants, etc. The expandable accumulator is preferably an elastomeric bladder, the function of which is to accumulate fluid from the supply tank under pressure. The volume of the bladder expands as pressurized fluid enters from the pump mechanism. As with most backpack sprayers, the pump mechanism is positioned adjacent to the bottom of the supply tank and is in fluid communication with the tank. The function of the pump mechanism is to pump fluid from the supply tank into the bladder. An intake valve, associated with an inlet opening of the bladder, enables a unidirectional flow of liquid from the pump to the bladder. Discharge of fluid from the bladder also occurs through the inlet opening upon the opening of a discharge valve.

  • Patent number: 5881493
    Abstract: A foam sprayer apparatus comprises a container and a manual air pump carried by the container. The pump is operable to manually pump air into the container and create an air head therein. A discharge channel establishes fluid communication between the interior and exterior of the container. The channel contains an air opening located inside the tank and above a level to which a supply of foaming composition is to be filled. An inlet of the discharge channel is located below the level to which a supply of foaming composition is to be filled. A foaming chamber is also included for causing turbulence in a fluid received from the discharge channel. A discharge valve controls the flow of fluid through the discharge channel and foaming chamber. When the valve is open, fluid flows from the discharge channel to the foaming chamber, and from the foaming chamber to a nozzle. The nozzle is in fluid communication with the outlet of the foaming chamber.

An intake valve, associated with an inlet opening of the bladder, enables a unidirectional flow of liquid from the pump to the bladder. Discharge of fluid from the bladder also occurs through the inlet opening upon the opening of a discharge valve. The discharge valve is normally closed to permit the bladder to accumulate a desired quantity of fluid.
