Hose sprayer assembly

A hose sprayer assembly comprising:

• a housing formed with a transverse opening and having a water passageway in fluid communication with said transverse opening, and further having a product passageway in fluid communication with said transverse opening;
• a trigger valve inserted into said transverse opening, said trigger valve being formed with a water port, a mixture port in fluid communication with said water port and a product port in fluid communication with said mixture port;
• said housing having an inner surface and an outer surface and an outlet aperture extending from said inner surface to said outer surface;
• and,
• said trigger valve being selectively aligned so that when said product port is simultaneously isolated from said product passageway, said water port is in communication with said water passageway and said mixture port is in communication with said outlet aperture.

A method for spraying an aspirated liquid/liquid mixture comprising the steps of:

• A) providing an annular housing formed with an outer surface and an inner surface;
• B) integrally molding an elastomeric membrane having a membrane inner surface to said inner surface, said membrane inner surface defining a transverse opening in said housing;
• C) inserting a trigger body into said opening, said trigger body being formed with an inlet port, an outlet port in fluid communication with said inlet port, and an aspiration port in fluid communication with said outlet port;
• D) rotatably mounting said trigger body in said housing;
• and
• E) simultaneously placing said inlet port in fluid communication with a pressurized first liquid source and placing said aspiration port in fluid communication with a second liquid source.
