Abstract:
A regulator and converter for fumigating a volatile material, under vacuum, into an internal combustion engine air intake flow comprising, a body that includes a center portion, an exhaust valve section, and end caps arranged to fit over outer surfaces of, respectively said center portion and said exhaust valve section, and including means for connecting said center portion, exhaust valve section and end caps together with said body including ports formed into a cavity in said center portion that includes means for mounting inlet and outlet hose means into said ports for passing engine coolant therethough heating said body, and which said center portion cavity is ported at separated outer surfaces and includes fittings in each of said ports for connection to the inlet and outlet hoses, respectively, that pass the flow of engine coolant therethrough; and the LPG passage is a pair of grooves that are formed across a face of said center portion and, in the assembly of the body, said pair of grooves are covered over by a flexible rubber gasket that is sandwiched between said center portion grooved face and a flat face of the exhaust valve section, and a source of liquid LPG that is vaporized in passage through at least one LPG passage that is separate from said cavity and is formed between an LPG port and an outlet port means into said body, with said flow traveling out of said outlet port means for passing vaporized LPG to a diesel engine air intake flow: and an LPG inlet valve means located in said body to close off LPG flow: means for operating said LPG inlet valve means to shut off LPG flow through said body upon operation of an LPG cutoff valve means to open in the presence of a vacuum in the engine inlet air flow of a pressure of approximately point five (0.5) inches of water column vacuum and to close at a pressure of approximately thirty (30) inches of water column vacuum and greater for controlling flow into said body.
