Abstract
A new type of device, useful as a fan among other applications, in which fluid flow is induced by providing within the device a chamber of constantly increasing volume and a chamber of constantly decreasing volume. Fluid moves through these chambers impelled by the rotation of a pair of members linked together for rotation about skewed axes. The members move within a chamber having a spherical surface, into which open ports for inward and outward fluid flow. The device may be used to assist in cooling components of an electronic system such as a computer system
Claims18
Apparatus comprising:
- a housing defining a chamber with a spherical surface, an inlet port opening through said housing into a hemisphere of said chamber, and an outlet port opening through said housing from the same hemisphere of said chamber;
- a planar, disk-like first rotatable member mounted within said housing for rotation relative thereto and positioned to bound a hemisphere within said chamber, the hemisphere communicating with said inlet port and said outlet port;
- and
- a planar second rotatable member mounted within said housing for movement relative to said housing and to said first rotatable member, said second rotatable member mounted in said housing for rotation about an axis skewed relative to the plane of said first rotatable member and coupled to said first rotatable member for oscillation about an axis lying in the plane of said first rotatable member;
- said rotatable members cooperating one with another and with said ports to define an expanding volume opening from said inlet port and a contracting volume opening to said outlet port;
- rotation of said first and second rotatable members inducing a flow of fluid through said ports and said chamber.

Apparatus comprising:
- a first housing enclosing a heat producing electronic system;
- and
- a fluid flow inducing device coupled to said heat producing electronic system for impelling a cooling flow of fluid across said heat producing electronic system, said device comprising:
- a second housing defining a chamber with a spherical surface, an inlet port opening through said second housing into a hemisphere of said chamber, and an outlet port opening through said second housing from the same hemisphere of said chamber;
- a planar, disk-like first rotatable member mounted within said second housing for rotation relative thereto and positioned to bound a hemisphere within said chamber, the hemisphere communicating with said inlet port and said outlet port;
- and
- a planar second rotatable member mounted within said second housing for movement relative to said second housing and to said first rotatable member, said second rotatable member mounted in said second housing for rotation about an axis skewed relative to the plane of said first rotatable member and coupled to said first rotatable member for oscillation about an axis lying in the plane of said first rotatable member;
- said rotatable members cooperating one with another and with said ports to define an expanding volume opening from said inlet port and a contracting volume opening to said outlet port;
- rotation of said first and second rotatable members inducing a flow of fluid through said ports and said spherical chamber.

Method comprising:
- rotating within a chamber which has a spherical surface a member positioned to define with the chamber a volume which is constantly expanding and a volume which is constantly contracting;
- coupling conduits for fluid flow to said volumes;
- and
- impelling flow of fluid through the chamber by the rotation of the member.
