Abstract
A variable volume chamber device is disclosed. The chambers may be defined by the space between four pivotally connected vanes contained within two side plates. The vanes may be connected so as to create a sealed interior chamber that may be used as a combustion chamber in an internal combustion engine, or as a pumping chamber in a pump or compressor. The four vane assembly may also form additional variable volume chambers between the vanes and a surrounding structure. The plurality of variable volume chambers may be interconnected to progressively act on a working fluid.
Claims41
A variable volume chamber device comprising:
- a first surface included in a first member spaced from and fixed relative to a second surface included in a second member, wherein the first surface extends in a first reference plane, the second surface extends in a second reference plane, and the first reference plane is parallel to the second reference plane;
- a first variable volume chamber disposed between the first surface and the second surface, said first variable volume chamber defined at least in part by the first surface, the second surface, and a first assembly including a first vane, a second vane, a third vane, and a fourth vane;
- a first pivotal connection between the first vane and the second vane, wherein the first pivotal connection is maintained in a fixed location relative to the first surface and the second surface;
- a second pivotal connection between the second vane and the third vane;
- a third pivotal connection between the third vane and the fourth vane;
- and
- a fourth pivotal connection between the first vane and the fourth vane.
