Abstract: A fluid drive coupling is provided which includes a platelike first member rotatably mounted within a chamber formed in a second member, the latter also being rotatably mounted. Both members are rotatable about a common axis and one of the members is driven by an external force. The chamber is formed into an annular fluid drive section having surfaces thereof in close proximity to substantial outer opposite surface portions of the first member whereby rotation of one member imparts rotation to the other member through a fluid disposed within the chamber drive section. The chamber is also formed into an inner section, a portion of which, disposed to one side of the first member, is separated into first and second fluid reservoirs interconnected to one another only through a port. A thermal responsive valve is mounted on the second member and is rotatable therewith. The valve effects opening and closing of the port in response to predetermined temperatures. An elongated cavity is formed in the second member adjacent to and in communication with a peripheral segment of the chamber drive section. An elongated skimming means is disposed in slip fit relation within the cavity and has a portion thereof projecting into the chamber drive section and encompassing a peripheral portion of the first member. When the first member is rotating in one direction relative to the second member, the skimming means will cause removal of fluid from the surfaces of the rotating first member encompassed thereby and divert the removed fluid into the cavity whereupon the fluid will flow from the cavity into the first reservoir.
