Rotating and reciprocating piston device

#This description relates to the field of engines and compressors. More particularly, this description relates to rotary type engines and compressors.

#An engine is a machine designed to convert energy into mechanical motion. A compressor is a device used for increasing pressure of a gas by reducing its volume.

#Various types of engines exist. Among them, internal combustion engines with reciprocating pistons are most popular in cars today. Another type of internal combustion engine is the Wankel engine in which triangular shaped rotor and an epotrochoid-shaped casing interact to create compression and expansion chambers. Yet another type of engines is a rotary engine which is an internal combustion engine where the radially-mounted cylinders and pistons rotate around a fixed crankshaft.

#Further features and advantages of the present disclosure will become apparent from the following detailed description, taken in combination with the appended drawings, in which:

#FIG. 1 is a schematic diagram showing a top plan view of an embodiment of a rotating and reciprocating piston device without one of its covers;

#FIG. 1a is a cut out view of the track plate of FIG. 1;

#It will be noted that throughout the appended drawings, like features are identified by like reference numerals.

#Many interesting applications for rotating and reciprocating piston device 10 exist. These applications include a four-stroke engine (FIG. 5), an electric generator (FIG. 11), a hybrid engine, a compressor (FIG. 39), and, in combination with a compressed air tank, an energy reservoir.

#Referring now to the drawings, and more particularly to FIGS. 1, 1a, 1b, 1c, 1d, 4, 4a, 4b, 4c, 4d, 4e and 39, there is shown a rotating and reciprocating piston device 10 in accordance with an embodiment. Device 10 comprises a top track plate 14a, and a shaft 15. The device 10 comprises a ring 11 and top and bottom track plates 14a and 14b.
