Abstract: Systems and methods are provided for pumps that deliver optimized torque characteristics and volumetric efficiency. A system includes a housing defining a surface and a rotor defining a face. A face clearance is defined between the face and the surface. The face clearance is variable in magnitude and determinative of target performance characteristics of the pump system. The housing is made of a material selected to have a thermal expansion characteristic and the rotor is made of a second material selected to have another thermal expansion characteristic. The thermal expansion characteristics deliver the target performance characteristics of the pump system.

Abstract: A fluid containing component is provided having a structure and a sump for storing a fluid. A gear baffle is disposed between the rotatable component and the structure. The gear baffle includes a first side end and a second side defining a gear cavity therebetween. The fluid displaced by rotation of a gear positioned within the gear baffle collects on inner surfaces of the gear baffle and is directed out of the gear baffle through at least one flow port of the baffle.

Abstract: An apparatus for passive control of fluid flow between at least two volumes includes a first volume containing a fluid agitator and a second volume containing a fluid. A baffle disposed between the first and second volumes includes at least one opening that allows fluid flow to occur between the first and second volumes. A flow control device is passively manipulated in response to a condition change of either the first or second volumes to effect flow through the at least one opening in the baffle.
