Hello all.

Here is a Wankel-like Rotary Engine:

The working surface whereon the seals abut is not a “cylindrical” surface but a 3D curved surface ending smoothly / tangentially on the side flat surfaces of the casing.

The typical “Wankel sealing grid” (wherein each combustion chamber is sealed by a set of two side seals, two apex seals and four button (or corner) seals) can be replaced by a single piece seal per combustion chamber.

Here is a PatWankel wherein the working surface is on the inner body (say as in the Liquid Piston engine):

One seal per combustion chamber, as in the reciprocating piston engines.

This five “cylinder” PatWankel rotary ( stereoscopic view, as at http://www.pattakon.com/pattakonStereoscopy.htm ) :

has two combustions per rotation of the inner body, i.e. as much as a two-rotor Wankel Rotary (say, Mazda RX-8).

Does the oval seal at bottom middle remind the Honda NR750?

Imagine this PatWankel engine at the back of an airplane pushing forwards:

The outer body (that with the cooling fins) spins at 4/5 (80%) of the speed of the inner body:

There is no eccentric shaft.

There are no balancing webs.

However it is perfectly balanced.
