Pressure Atomizing Oil Burner Equipment and Systems – Firing Assemblies
A fuel oil pressure regulating, by-pass valve, beautifully crafted and styled for the discerning eye in brass/bronze. It exemplifies the range of peripheral devices engineered by a new generation of technology manufacturers, starting in the late 1920’s, innovators and suppliers to the automatic oil heating market. Together, they built the system of interacting and mutually supporting components and parts required for safe, efficient, reliable, automatic home heating in Canada, Detroit Lubricator, Circa 1940.
Features: Embossed Detroit Lubricator logo; Beautifully embossed brass name label
Technical Significance:
Of spring compensated, piston design, this fully adjustable by-pass valve would be a technical break through in its times, allowing excess fuel oil to be automatically circulated back to the oil tank from the oil burner. Oil pump engineering would later incorporate a pressure regulating, by-pass valve function as an integral part of the pump itself, see Note 1 [See Group 12.06 historic artifacts]
The device stands as a reminder that the commitment to automatic heating for the Canadian home brought with it a vast range of engineering challenges. Required would be a network of fully automated devices, mechanical, electrical and hydraulic, all of which must work together, smoothly and systemically to produce the required performance characteristics – including self-regulation, safely, reliability, efficiency, and affordability- all quite unimagined a decade earlier
It exemplifies the great precision made possible in the 1930’s and 40’s, given the limited engineering materials and production machining methods of the times.
It exemplifies, too, the range of peripheral devices engineered and manufactured by a new generation of companies, starting in the late 1920’s, for the automatic oil heating market, part of the system of interacting and mutually supporting components and parts required.
Industrial Significance:
Demonstrates the vast engineering know-how accumulated by fluid flow valve speciality companies of the time, here Detroit Lubricator, whose valves dominated many facets of the HVACR industry, ubiquitous through much of the 20th century [See also Group 3.01 and 3.02 historic artifacts]
