    Abstract: A sprayer head may be removably mounted onto a concentrate tank of a hose end sprayer. The sprayer head may include a valve assembly having a valve body having a first axis of rotation selectively movable between a closed orientation, a wet mode orientation, and a dry mode orientation. A metering plate may include a first annular series of spaced-apart flow-metering holes with each successive respective flow-metering hole has an increasing hole diameter adapted to withdraw a selectively adjustable amount of a concentrate from the concentrate tank when the valve body is in either the wet mode orientation or the dry mode orientation. The metering plate has a second axis of rotation which is non-coaxial with the first axis of rotation.

    Abstract: A hose end sprayer includes a concentrate tank and a sprayer head. The sprayer head has an inlet end, an outlet end and a flow tube, along with a suction tube and a valve. When the sprayer head is closed, neither the first nor the second flow orifice communicates with the flow opening and the concentrate opening is closed by the valve body. When the sprayer head is in wet mode, the vent opening communicates with the concentrate opening as concentrate is drawn into the flow tube. When the sprayer head is in dry mode, the concentrate orifice communicates with the concentrate opening to direct a portion of the fluid into the concentrate tank. A metering plate injects a selectively adjustable amount of concentrate into the fluid stream. The sprayer head may further include a concentrate basket to hold a dry product within the concentrate tank.

    Abstract: An internal pump backpack sprayer system includes a first tank, a second tank and a pump unit. The first tank includes a tank housing for holding a fluid. The second tank is received within the first tank and receives a pressurized fluid. The pump unit has a cylinder housing with first and second inlets and first and second outlets, a piston within a cylinder and a pressure discharge assembly. When the piston moves in an up-stroke, fluid is drawn from the first tank through the first inlet while all or some pressurized fluid is discharged through the pressure discharge assembly with a remainder being discharged to the second tank through the second outlet. When the piston moves in a down-stroke, fluid is drawn from the first tank through the second inlet while pressurized fluid is discharged to the second tank through the first outlet.

    Abstract: An external by-pass circuit for a positive displacement pump includes a flow diverter valve coupled to the pressure port of the pump. The flow diverter has an end coupled with a high flow output and another end coupled with a low flow output. The low flow end includes a by-pass arm coupled to and input flow fitting. The flow diverter valve further includes a ball valve to direct fluid to either the high flow or low flow output. The input flow fitting is coupled to the suction port of the pump at the one end and couples with a fluid source at the other end. The input flow fitting includes a flow control arm which includes a needle valve to selectively control flow within the flow control arm. The flow control arm also includes a by-pass fitting fluidly coupled with the by-pass arm of the flow diverter valve.

    Abstract: A hose end spray head apparatus includes a spread head body and a hose coupling. The spray head body includes a mixing body and a spray outlet arm formed as a unitary construction. The spray outlet arm extends outwardly from the mixing body and includes a spray bore to discharge a mixed fluid. The spray bore communicates with atmosphere via a first radial sidewall bore and a first offset top surface bore. An axial bottom surface bore extends from the bottom surface to the spray bore and is draws product from a container so as to inject the product into the spray bore. A second radial sidewall bore is configured to communicate an open interior of the container with atmosphere. The hose coupling is secured to the mixing body and mounts to a fluid supply to form the mixed fluid which is discharged through the spray bore.
