DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The field to which this invention relates is vehicular transportation.
BACKGROUND ART
Conventional vehicular transportation even in crowded urban environments has required toleration of sulfur and carbon-containing chemical environmental pollutants produced by internal combustion engines and ozone emission and high battery cost of electrically operated vehicles. By the apparatuses and process of this invention, chemical pollution is ratuses and process of this invention, chemical pollution is eliminated. Further, the systems herein described utilize what might otherwise be lost energy on braking a moving vehicle and also utilize usual lost exhaust pressure energy.
The prior art has not taught or provided pollution-free transportation vehicles that provide conventional passenger seating and comfort at costs competitive with conventional internal combustion engine-powered vehicles nor air engines that cycle exhaust and vehicular energy.
Representative prior art is as follows: U.S. Pat. No. 193,631 Pneumatic Engine, July 31, 1871 to J. F. Allen; U.S. Pat. No. 3,396,631 Fluid Driven Engine With Improved Fluid Amplifier Valve Means, August 13, 1968, to K. E. Woodward; Marco Matteucci, History of the Motor Car, Crown Publishers, New York, 1970, pages, 14-17; Terry R. Miller, Air Powered Cars, Tri-State Printing Co., Galena, Kansas, 1979, pages 1-5.
DISCLOSURE OF INVENTION
The apparatus and processes disclosed utilize compressed air storage and control systems to actuate vehicles and so provide vehicular transport as shown in FIG. 1 for people while avoiding production or distribution of exhaust gases that are harmful to humans.
As shown in the arrangement of tank assemblies in FIGS. 3 and 15, the exhaust energy of the engine 25 and braking energy of the vehicle are recovered for further use in propelling the vehicle 20; and as shown in the engine system of FIGS. 6 and 12-14 not only are the recovered gases used to propel the vehicle but also the energy of the exhaust gases recovered from such operation are stored for further use to propel the vehicle.
BRIEF DESCRIPTION OF DRAWINGS
FIG. 1 is a diagrammatic overall view of a vehicle 20 using an engine 25 according to this invention.
FIG. 2 is a top view of the engine 25 of vehicle 20 as seen in the direction of the arrow 2A of FIG. 1.
FIG. 3 is a diagrammatic expanded view of portions of the system 120 to show functional relationship of the parts thereof during operation of that system.
FIGS. 4 and 5 show steps in a sequence of operation of the piston, crankshaft, and other major portions of the engine 25 during a cycle of operation of that engine.
FIG. 6 shows a variation in structure of the apparatus of FIGS. 3, 4 and 5.
FIGS. 7 and 8 show the air injector valve in two different positions during its operation.
FIG. 9 is in part a sectional view of air volume control slide valve 46 along plane 9A--9A of FIG. 3, and in part a view with part of the slide removed.
FIGS. 10 and 11 show a tank valve; FIG. 10 is a vertical sectional view along the vertical plane shown by line 10A--10A of FIG. 11 and FIG. 11 is a vertical longitudinal section along the plane 11A--11A of FIG. 10.
FIG. 12 is a diagrammatic view of tank assemblies and engine in one system according to this invention.
FIG. 13 is an enlarged view of zone 13A of FIG. 12.
FIG. 14 is an enlarged diagrammatic view of the changeover valve 90 to which connections are shown in FIG. 13.
FIG. 15 is a diagrammatic showing of another set of connections of the tank assembly 24 and engines as in FIGS. 3-6 in a vehicle as shown in FIG. 1.
BEST MODES FOR CARRYING OUT THE INVENTION
A vehicle 20 shown in FIG. 1 comprises a rigid frame 50 firmly attached to and supporting a passenger compartment 21, wheels as 22 and 23, a valve and tank assembly 24 and engine 25. Valve and tank assembly 24 comprises a plurality of like high pressure main tank and recovery tank assemblies 26, 27, 29 and 49. Valve and tank assembly 24 and engine 25 form an engine system 120, as shown in FIG. 3. While FIG. 1 shows th
