ABSTRACT:
A displacement or power mechanical oscillator comprises an oscillation space constituted by a sector of an annular cavity, having a rectangular cross-section in a plane through the axis of the cavity and vertically oriented plane of symmetry. The cavity contains a sealing liquid and a vane in closed matching relationship with the inner walls of the cavity. The vane is symmetrically oscillatable with the liquid in the narrow gaps between vane and cavity walls providing a liquid dynamic seal.
