Title:
REVERSIBLE ONEEWAY FLUID PUMP
Document Type and Number:
Japanese Patent JPS5593989
Kind Code:
A
Abstract:
This invention relates to a reversible unidirectional-flow liquid pump.
The pump includes a pumping assembly comprising a gerotor type of gear-set (46, 50), and has its inlet (66-68) in series fluid-flow connection with a valve (70) adapted, upon reversal of the direction of pump rotation, to cause a hydraulic lock to be formed in the gear-set whereby the pumping assembly is repositioned such as to ensure continued unidirectional liquid flow despite the reversal of rotation.
The pump, which is particularly suitable for use as an oil pump in refrigerant compressors, does not rely upon friction in repositioning the pumping assembly.
