Rotary Expander Engine.
Abstract
The patent application relates to an expander engine of Wankel type and more particularly to a low noise, high power, light weight and compact expander engine for use primarily in underwater propulsion systems operating with either an open cycle or a closed thermal cycle. The engine features minimum unbalanced forces and elimination of balance weights because its rotating parts rotate about their centers of mass. The high inertia of its rotating housing eliminates the need for a fly wheel and rotation in a plane normal to the centerline of the engine results in a preferential directivity to any residual disturbing forces. The elimination of balance weights and fly wheel provides a means for minimizing clearance volume from the inlet valve to the working space.
