Example fluid circuits (e.g., within aircrafts) include first and second pump assemblies. The first pump assembly has an electric motor and a first fluid pump. The first fluid pump is coupled to the electric motor and has a case drain port that is in fluid communication with a case drain region of the first fluid pump. The second pump assembly is powered by hydraulic pressure from the first fluid outlet of the first fluid pump and functions to augment flow through the case drain region of the first fluid pump.

A fluid flow regulator includes a valve assembly defining a fluid passage. The fluid passage includes a first port, a second port, a sensing orifice disposed between the first and second ports, a first orifice disposed between the first port and the sensing orifice and a second orifice disposed between the sensing orifice and the second port. A first flow area of the first flow orifice varies in response to differential pressure across the sensing orifice as fluid flows through the fluid passage in a first direction from the first port to the second port. The first flow area is fixed as fluid flows through the fluid passage in an opposite second direction. A second flow area of the second orifice is fixed as fluid flows through the fluid passage in the first direction and varies as fluid flows through the fluid passage in the second direction.
