Liquid sealed vane oscillators

A liquid sealed oscillator, comprising 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 which cavity contains a sealing liquid, and a vane of smaller included sector angle than the said oscillation cavity and having is surface in closely matching relationship with the inner facing wall of the said cavity, wherein the said vane is symmetrically oscillatable with the said liquid in the narrow gaps between the vane and cavity walls providing a liquid dynamic seal and wherein the vane is fully submerged in the sealing liquid, however, the latter does not completely fill the oscillation cavity, thus, effectively leaving two separate, symmetrical pressure chambers above the free surface of the liquid, and the said pressure chambers containing pressure fluid, preferably inert gas.
