【発明の名称】耐凍性回転流体管理装置
Document Type and Number:
Japanese Patent JP2002501602
Kind Code:
A
Abstract:
The use of a working fluid that is subject to freezing is achieved in a fluid system including a rotating fluid management device (RFMD) (10) and a pair of fluid flow loops (22, 27) connected to the RFMD (10) and arranged so that the inventory of working fluid in the system drains to the RFMD (10) when the system is not operating. The RFMD (10) includes a housing (32) having an inlet port (60, 64), a first outlet port (56), a second outlet port (62), a reservoir (34) mounted on the housing (32) for rotation about a vertical axis (38), a return (92, 93) for directing working fluid from the inlet port (60, 64) to the reservoir (34), a pitot tube (116) fixed to the housing (32) and extending to adjacent radially outer location (118) in the reservoir (34) for directing liquid phase working fluid from the reservoir to the first outlet (62), and a vent (121) located radially inward from the radially outer location (118) for directing gas phase working fluid from the reservoir (34) to the second outlet port (56). The reservoir (34) includes a storage volume (84) sufficient to store the entire inventory of working fluid in the system when the system is not operating. The storage volume (84) is defined by an upwardly opening, concave surface of revolution (86) centered on the vertical axis (38).
