Abstract
Abstract The pressurized chemical dispenser of the present invention is coupled to a conduit through which a supply of pressurized fluid is circulating. The system to which the invention is coupled must also include a device coupled in series with the conduit which creates a pressure differential across the input and output sides of the device such that the pressure on the input side exceeds the pressure on the output side. The chemical dispenser includes an offset cavity which is coupled to the conduit on the higher pressure side of the pressure differential device. A fluid tight reservoir stores a supply of fluid soluble chemical and includes an input and an output conduit. The input conduit has a first end which is coupled to the reservoir and a second end which is coupled to the offset cavity. The first end of the output conduit is coupled to the reservoir while a second end is coupled to the fluid conduit on the lower pressure side of the pressure differential device. The pressure differential established across the pressure differential device causes fluid to flow through the offset cavity into the reservoir and then into the lower pressure side of the fluid conduit. The fluid soluble chemical is thus injected at a controlled rate into the fluid.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
245 words
A chlorinator system for use with a source of fluid such as a pool comprising: fluid pump means for pumping fluid from the source to an output side; a first fluid supply conduit having a first and second end, said first end coupled to the output side of said fluid pump means; a filter unit having a filter input side and a filter output side said filter input side coupled to the second end of said first fluid supply conduit; a second fluid supply conduit coupled to the output side of said filter unit whereby a pressure differential is created across the filter unit between said first conduit and said second conduit; an offset chamber disposed above and coupled to said first fluid supply conduit; a first coupler having an orifice on an upper most surface thereof, said first coupler disposed in said offset chamber whereby any fluid flow from said first fluid supply conduit and into said first coupler has a substantial vertical component thereby substantially preventing any non-soluble particles from flowing into the orifice of the first coupler; a fluid type reservoir for storing a supply of a fluid soluble chemical, including an intake orifice and an output orifice; and means disposed through said input orifice and in communication with said first coupler for creating a circulating flow of fluid inside said fluid type reservoir whereby the circulating flow assists in dissolving the supply of fluid soluble chemical in the fluid type reservoir.
Claim 2
Dependent Claim
245 words
A chlorinator system for use with a source of fluid such as a pool comprising: fluid pump means for pumping fluid from the source to an output side; a first fluid supply conduit having a first and second end, said first end coupled to the output side of said fluid pump means; a filter unit having a filter input side and a filter output side said filter input side coupled to the second end of said first fluid supply conduit; a second fluid supply conduit coupled to the output side of said filter unit whereby a pressure differential is created across the filter unit between said first conduit and said second conduit; an offset chamber disposed above and coupled to said first fluid supply conduit; a first coupler having an orifice on an upper most surface thereof, said first coupler disposed in said offset chamber whereby any fluid flow from said first fluid supply conduit and into said first coupler has a substantial vertical component thereby substantially preventing any non-soluble particles from flowing into the orifice of the first coupler; a fluid type reservoir for storing a supply of a fluid soluble chemical, including an intake orifice and an output orifice; and means disposed through said input orifice and in communication with said first coupler for creating a circulating flow of fluid inside said fluid type reservoir whereby the circulating flow assists in dissolving the supply of fluid soluble chemical in the fluid type reservoir.
Claim 3
Dependent Claim
90 words
The pool chlorinator of claim 2 wherein said means for creating a circulating flow comprises a pipe disposed through a side of the fluid type reservoir, and having an opening at the bottom surface of the end of said pipe; and a baffle plate angularly disposed and connected to the end of said pipe whereby the flow out of the opening is oriented towards the side walls of the fluid type reservoir to create a circulatory flow inside said fluid type reservoir to assist in dissolving the fluid soluable chemical.
Claim 4
Dependent Claim
31 words
The pool chlorinator of claim 1 further comprising means disposed intermediate to the means for creating a circulating flow and the first coupler, for controlling the rate of flow of fluid.
Claim 5
Dependent Claim
18 words
The pool chlorinator of claim 3 wherein said means for controlling comprises: a manually adjustable flow control valve.
Claim 6
Dependent Claim
34 words
The pool chlorinator of claim 1 further comprising a tube having one end coupled to the output orifice of the fluid type reservoir, and the other end coupled to said second fluid supply conduit.
Claim 7
Dependent Claim
18 words
The chlorinator of claim 1 wherein said fluid type reservoir has an internal volume of approximately one quart.
Claim 8
Dependent Claim
56 words
The pool chlorinator of claim 1 wherein said fluid type reservoir comprises: a cylindrical member having an open top with an internally threaded top portion; a cylindrical cap having an externally threaded portion and having a hand grip thereon whereby said cylindrical cap can be threaded on to the cylindrical member for a water tight seal.
Claim 9
Dependent Claim
15 words
The pool chlorinator of claim 7 wherein said fluid type reservoir is made of plastic.
Claim 10
Dependent Claim
32 words
The pool chlorinator of claim 1 further comprising a tube having one end coupled to the output orifice of said fluid type reservoir and another end discharging into said source of fluid.
Claim 11
Dependent Claim
17 words
The pool chlorinator of claim 5 or 9 further comprising a check valve coupled to said tube.
