Abstract
A hose-end sprayer assembly connectable to at least one container of product to be dispensed has an elongated housing for a venturi tube assembly rotatable about its central axis and devised to selectively open and close a product inlet opening as well as its associated vent valve, an independently controllable liquid carrier valve being provided for opening and closing the carrier liquid flow through the venturi tube duct in the venturi tube assembly can be devised for opening and closing inlet product inlet openings of separately stored chemical products sequentially or simultaneously.
Claims32
A hose-end sprayer assembly for connection to at least one container having a first product chamber for holding product to be dispensed comprising:
- an elongated housing having a carrier liquid inlet passage, a first liquid product inlet opening and a first vent port both in communication with the first product chamber;
- rotary product flow diverter means mounted within said housing and coaxial therewith for selective rotation about a central axis thereof and having a liquid duct extending along said axis between inlet and outlet ends thereof, said diverter means having liquid product inlet port in communication with said liquid duct;
- said diverter means being configured to block said first liquid product inlet opening from said liquid duct in a first rotative position of said diverter means and to connect said first liquid product inlet opening with said liquid duct in a second rotative position of the diverter means;
- said diverter means being further configured to open and close the vent port respectively in the second and first rotative positions of the diverter means;
- and an independently movable liquid carrier control valve selectively operable for interconnecting said carrier liquid inlet passage with said liquid duct and for disconnecting the liquid passage from the liquid duct in a closed position.
A sprayer assembly for connection to a container having at least a first product chamber for holding product to be dispensed, comprising:
- a tubular housing having a carrier liquid inlet passage for communication with a source of carrier liquid, the housing having a first liquid product inlet opening and a first vent port both in communication with the first product chamber;
- a tubular valve rotatable about its central axis coaxial with and contained within the housing, the valve defining a liquid duct in communication with said carrier liquid inlet passage, the valve having a liquid product inlet port opening into said liquid duct;
- said valve being rotatable between at least first and second positions and being configured such that in said first and second positions said liquid product inlet opening is respectively blocked from and connected with said liquid duct and said vent port is respectively closed and opened;
- and a liquid carrier control valve for opening and closing said carrier liquid inlet passage to said liquid duct.
A sprayer assembly for connection to first and second chambers for holding products to be dispensed, comprising:
- a tubular housing having a carrier liquid inlet passage for connection with a source of cater liquid, the housing having a first liquid product inlet opening and a first vent port both in communication with the first chamber, and a second liquid product inlet opening and a second vent port both in communication with the second chamber;
- the housing containing a coaxial, tubular valve defining a liquid duct in communication with said carrier liquid inlet passage;
- said valve being configured to block said first and second liquid product openings from said liquid duct in at least one first position first and third positions of the valve, to connect at least one of said first and second liquid product inlet openings with said liquid duct in at least one second position of the valve, to close the first and second vent ports in the at least one first position of the valve, and to open at least one of the first and second vent ports in the at least one second position of the valve;
- and a movable liquid carrier control valve for opening and closing said carrier liquid inlet passage to said liquid duct.
