Abstract (en)
A horizontal shaft oil pump (11) is provided for use in a compressor (10) comprising an outer housing (12) having an inlet (30), an outlet (24), an oil sump (48), and a crankcase (42) mounted therein. The crankcase has a generally vertically disposed passageway (46) therein in communication with the oil sump, and a crankshaft (52) is horizontally rotatably received in a bore (50) in the crankcase. A reduced diameter portion (84) of the crankshaft forms between the crankshaft and crankcase an annular chamber (86) in communication with the passageway, and a pair of oppositely angularly disposed helical grooves (88, 90) are disposed in the crankshaft on opposite sides of and in communication with the annular chamber. Upon rotation of the crankshaft, a low pressure area is developed in the annular chamber causing lubricant to be drawn upwardly through the crankcase passageway and into the annular chamber. The rotating helical grooves deliver lubricant from the annular chamber to opposite ends portions of the crankshaft for lubricating bearings and other moving parts.
