Abstract
Abstract A burner control for a system having fluid burner, a pump, a nozzle, an air control louver with a fluid operator and a fluid bypass. A main valve connects the pump and the nozzle. A second valve connects the pump, the main valve, the louver operator and the fluid bypass, and additionally the louver operator connects with the fluid bypass. The control in operation controls the operator of an air louver apparatus and fluid flow through the nozzle and the bypass in a low fire condition and a high fire condition.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
In a fluid burner apparatus having a pump means, a nozzle, an air control louver means with a fluid operator, and a fluid bypass means, the improvement of a burner fluid control system therefor, comprising: a. a main valve means connected in fluid communication with said pump means and said nozzle, b. a second valve means connected in fluid communication with said pump means, said main valve means, said louver means operator and said fluid bypass means, and c. means connecting said louver means operator and said fluid bypass means, said control system is adapted in operation to control said louver means operator and fluid flow through said nozzle.
Claim 2
Dependent Claim
109 words
In a fluid burner apparatus having a pump means, a nozzle, an air control louver means with a fluid operator, and a fluid bypass means, the improvement of a burner fluid control system therefor, comprising: a. a main valve means connected in fluid communication with said pump means and said nozzle, b. a second valve means connected in fluid communication with said pump means, said main valve means, said louver means operator and said fluid bypass means, and c. means connecting said louver means operator and said fluid bypass means, said control system is adapted in operation to control said louver means operator and fluid flow through said nozzle.
Claim 3
Dependent Claim
60 words
The control system of claim 1, wherein: a. said pump means has means to regulate the maximum operating pressure thereof, b. said bypass means has means to return the fluid to a fluid reservoir at a predetermined pressure, and c. said air control louver means operator has means to open and close an air louver apparatus of said burner apparatus.
Claim 4
Dependent Claim
48 words
The control system of claim 2, wherein: a. said main valve means is constructed and adapted in operation to start and stop fluid flow to said nozzle, and b. said second valve means is constructed and adapted in operation to control fluid flow to said louver means operator.
Claim 5
Dependent Claim
56 words
The control system of claim 3, wherein: a. said louver means operator has a normally retracted fluid cylinder means operable on receipt of fluid under pressure to extend, and b. said bypass means is a pressure relief valve means constructed and adapted in operation to open at a specified pressure thereby passing fluid to said reservoir.
Claim 6
Dependent Claim
132 words
The control system of claim 4, wherein: a. said pump means has an inlet in fluid communication with said fluid reservoir, a main outlet having said means to regulate pressure, and a return outlet connected by a conduit means to said bypass means, b. said main valve means is a normally closed valve having an outlet connected by a conduit means to said nozzle, and having an inlet connected by a conduit means to said pump means main outlet, c. said second valve means is a three-way valve having the inlet connected said pump means main outlet, one outlet connected said bypass means, the other outlet connected said louver means operator, and d. said louver means operator is connected to said oil reservoir for the return of fluid thereto when in operation.
Claim 7
Dependent Claim
129 words
The control system of claim 4, wherein: a. said pump means has an inlet in fluid communication with a fluid reservoir, a main outlet having said means to regulate pressure, and a return outlet in fluid communication with said bypass means by a conduit, b. said main valve Means is a normally closed valve and is connected to said nozzle by means of a conduit, having an inlet conduit connecting same to said pump means main outlet by a pump conduit means, c. said second valve means is a three-way valve having the inlet thereof connected said pump means outlet conduit, one outlet thereof connected said fluid reservoir, and the other outlet thereof connected said louver means operator, and d. said louver means operator is connected said bypass means.
Claim 8
Dependent Claim
110 words
The control system of claim 4, wherein: a. said pump means has an inlet in fluid communication with a fluid reservoir, a main outlet having said means to regulate pressure and a return outlet connected by a conduit means to said bypass means, b. said nozzle is connected via a conduit means to the outlet of said main valve means, c. said pump means outlet is connected via a conduit to the inlet of said main valve means and the inlet of said second valve means, and d. said louver means operator is connected via a conduit to the outlet of said second valve means and to said bypass means.
Claim 9
Dependent Claim
28 words
The control system of claim 7, wherein: a. said main valve means is a normally closed valve, and b. said second valve means is a normally closed valve.
Claim 10
Dependent Claim
34 words
The control system of claim 1, wherein: a. said main valve means is a closable and openable solenoid actuated valve, and b. said second valve means is a closable and openable solenoid actuated valve.
