摘要： 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 first sealing surface and the second sealing surface having the first position wherein the first sealing surface and the second sealing surface cooperate to prevent the flow of liquid between the piston and the shaft. The first sealing surface and the second sealing surface also has a second position wherein the first sealing surface and the second sealing surface permit the flow of liquid between the piston and the shaft. The piston is formed from a single piece said piston and defines an inner annular surface surrounding the shaft and an upper outer annular surface sized and shaped to form a sealing engagement with said interior wall of the body and a lower outer annular surface sized and shaped to form a sealing engagement with the interior wall of said body.

摘要： An aspiration type chemical sprayer for dispensing small quantities of a liquid based chemical into a stream of carrier fluid is disclosed. The sprayer includes a sprayer head assembly sealingly mounted onto a container holding chemicals such as pesticides or fertilizers. A unitary valve in the sprayer head assembly controls carrier fluid flow from a pressurized source of water while simultaneously providing a controlled aspiration rate and full communication of the container interior to atmospheric pressure. The valve additionally includes simultaneously closure of the carrier fluid, aspiration and vent passageways so as to seal the chemical in the container when the sprayer is not being used.

摘要： Disclosed herein are various embodiments related 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. In one embodiment, the assembly also includes a sealing member that may be biased in one direction and actuated to open and close the vent passage.

摘要： 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.
