Abstract
A fluid reservoir and associated fluid circulation system and method are disclosed. The fluid reservoir is rotatable into any one of various rotational orientations and includes a housing defining an interior chamber that is divided into a working fluid chamber and a gas chamber by a membrane. An inlet port is fluidically coupled with the working fluid chamber to provide working fluid into the working fluid chamber and an outlet port is fluidically coupled with the working fluid chamber to remove working fluid from the working fluid chamber. A bleed channel extends a length along an outer periphery of the working fluid chamber and is fluidically open to the working fluid chamber along the length of the bleed channel. A bleed port is fluidically coupled with only a portion of the bleed channel and bleeds gas out of the working fluid chamber via the bleed channel. The length of the bleed channel is such that at least a portion of the bleed channel is open to an uppermost portion of the working fluid chamber when the housing is in any one of the various rotational orientations.
