A chemical aspiration sprayer head includes a carrier channel having an inlet, an outlet through which the carrier fluid exits, and an expansion chamber in between the inlet and outlet, a chemical supply channel in flow communication with the expansion chamber of the carrier channel through an aspiration opening, and a bleed line extending from the chemical supply channel between the aspiration opening and the liquid chemical, the bleed line connecting the chemical supply channel in flow communication to ambient air. A control valve assembly is seated in the sprayer head to simultaneously engage the carrier channel and the bleed line and with the carrier channel open, selectively open and close the bleed line to selectively permit ambient air to be drawn into the chemical supply channel in response to the aspiration flow produced by the flow of carrier fluid.

A pump assembly including a pump attachment adapted to form a nonaerosol pump sprayer, and a method of using the same. The apparatus includes an attachment having a pump sprayer that is pressurized on the upstroke. The attachment includes a body that defines a chamber, a shaft moveable between a first and second position in the body, a piston, a first valve and a second valve. The first valve permits the flow of fluid into the chamber and restricts the flow of fluid out of the chamber. The second valve moves between an open position-permitting the flow out of the chamber and a biased closed position restricting the flow out of the chamber. When the shaft is moved to the first position, the shafts moves the second valve from the closed position to the open position. An apparatus with a bleeder orifice for automatically releasing pressure is also disclosed.

An assembly including a pump attachment particularly adapted to form an nonaerosol pump sprayer, and a method of using the same. The apparatus desirably includes an attachment having a pump sprayer which is pressurized on the upstroke enabling the sprayer to be shipped and stored in a relaxed position. The attachment includes a body, a coupling, a shaft, a piston, an inlet valve and a biasing member. The body defines an elongate chamber having the first end, second end, and an interior wall extending between the first end and second end. The coupler is sized and shaped to secure the body to the neck of a container. The shaft extends through the opening in the first end of the chamber and defines an internal flow channel. The piston is reciprocally mounted within the chamber and includes an inner annular surface surrounding the shaft and an outer annular surface sized and shaped to form a sealing engagement with the interior wall of the body. The attachment defines a sealing surface substantially fixed with respect to the piston and a second sealing surface substantially fixed with respect to the shaft.

The present invention relates to a chemical sprayer that includes a chemical passage, a carrier fluid passage, a vent passage, a valve chamber and a valve. The valve is moveably positioned within the valve chamber and defines at least partially a first passage and a second passage that can be selectively placed in communication with the chemical and chemical fluid passages. The valve also includes one or more seal portions positioned on the valve so as to block [both] a vent passage, the chemical or the carrier fluid passages when said valve is in the closed position. The second passage also preferably forms at least in part an outlet of the sprayer head assembly. A suction generating surface is also preferably defined by the valve.

The present invention relates to a chemical sprayer that includes a sprayer head assembly and a container. The container defines a cavity for storing a chemical to be sprayed. The sprayer head assembly includes a chemical passage, a carrier fluid passage, a vent passage, a valve chamber and a valve. The chemical passage is communication with the cavity. The carrier fluid passage is in communication with a carrier fluid source. Both the carrier fluid and chemical passages are in communication with the valve chamber. The valve is moveably positioned within the valve chamber and defines at least partially a first passage and a second passage. The first passage is configured so as to be in communication with the chemical passage when the valve is in an open position. The second passage is configured so as to be in communication with the carrier fluid passage when the valve is in the open position. The first and second passages are also configured so as to not be in communication with the chemical and carrier fluid passages when said valve is in a closed position.

A sprayer head assembly comprises a chemical passage, a carrier fluid passage, and a housing that has an outer surface and an inner surface, which defines a valve chamber configured to be in communication with the chemical and carrier fluid passages. A valve is moveably positioned within the valve chamber between at least a first position, a second position and a third position. The valve defines a first passage, a second passage and a chemical inlet passage that is in communication with the second passage. The valve is configured such that, in the first position, the valve blocks the chemical and carrier fluid passages, in the second position, the first passage is configured to be in communication with the carrier fluid passage while the valve blocks the chemical fluid passage, and in the third position, the second passage is configured to be in communication with the carrier fluid passage and the chemical inlet passage is configured to be in communication with the chemical passage.
