ABSTRACT:
A rotary engine of the trochoidal type in which the rotor and the profile of a basically trochoidally shaped inner housing wall bear such relationship to one another that when the differential in pressure in the flanking chambers is Greatest, the rotor apex seals are deliberately caused to stroke out, so that the resulting friction between the outwardly stroking apex seals and the sides of the rotor slots, so modifies the outward forces acting on the seals that the contact force between the seals and the housing wall are significantly less than they would be without such outward stroking of the apex seals. In one embodiment of the invention, the outward stroking of the apex seals results from the outward displacement of the profile of the inner housing wall surface along those stretches thereof at which the pressure differentials are greatest and, in another embodiment, the desired outward stroking is obtained by using an oversized two lobed-trochoidal profile for the inner housing wall and shifting the housing with respect to the rotor shaft along the major axis of the trochoid.
