Dispenser for anti-corrosion fluids

Abstract

There is a dispenser for the delivery of an anti-corrosion fluid during flushing of a marine engine cooling system. The dispenser comprises a housing 1′ with a chamber 2 ′ for the anti-corrosion fluid, an inlet 5 ′ to the housing for connection to a supply of fresh water, an outlet 6′ from the housing for connection to the cooling system and a valve 3 ′ for selectively diverting inlet water either directly to the cooling system or through a mixing 3 A, 3 B so that the water is combined with the anti-corrosion fluid from the chamber 2 ′ before entering the cooling system.

I claim:  
     
         1 . A dispenser for the delivery of an anti-corrosion fluid during flushing of a marine engine cooling system, said dispenser including a housing with at least one chamber for said anti-corrosion fluid, an inlet to said housing for connection to a supply of fresh water, an outlet from said housing for connection to said cooling system and a valve for selectively diverting inlet water either directly to said cooling system or through a mixing means whereby said water is combined with the anti-corrosion fluid from said chamber before entering said cooling system.  
     
     
         2 . The dispenser as claimed in  claim 1  wherein said valve includes a shaft which is rotatable in a sleeve within said housing.  
     
     
         3 . The dispenser as claimed in  claim 2  wherein said shaft has apertures extending diametrically therethrough.  
     
     
         4 . The dispenser as claimed in  claim 3  wherein said apertures are alignable with ports in said sleeve.  
     
     
         5 . The dispenser as claimed in  claim 4  wherein when said valve is at a first position said apertures are disposed at right angles to said ports whereby flow of inlet water through said chamber is blocked and when said valve is at a second position the apertures are aligned with said ports whereby a portion of the inlet water flows through said chamber to mix with said anti-corrosion fluid.  
     
     
         6 . The dispenser as claimed in  claim 5  wherein when the flow of inlet water through said chamber is blocked said water flows to the outlet through a passageway around the periphery of said chamber.  
     
     
         7 . The dispenser as claimed in  claim 6  wherein said apertures include an upper aperture adjacent the top of said sleeve and a lower aperture adjacent the bottom of said sleeve with said lower aperture being downstream of said upper aperture whereby when said valve is at the second position said it portion of the inlet water enters the chamber through said upper aperture and exits through said lower aperture.  
     
     
         8 . The dispenser as claimed in  claim 7  where said valve has settings intermediate said first and second positions.  
     
     
         9 . The dispenser as claimed in  claim 8  wherein said housing is formed from moulded plastic.
