Abstract
An apparatus for removing vaporizable impurities from lubricating oil, or the like, including: a housing; an oil inlet fitting adjacent the top of and communicating with the housing, such fitting having a downwardly directed, intermediate inlet port, laterally and downwardly directed side inlet ports on opposite sides of the intermediate port, and an external groove interconnecting the side and intermediate ports; an electrical heating element below the intermediate port and having the form of a conical spiral with its larger end uppermost; and a ball in and supported by the upper end of the conical spiral in a position to have impinge thereon oil discharged by at least the intermediate port. The ball serves to distribute the oil impinging thereon uniformly over the inverted conical spiral. When the oil is cold, the external groove interconnecting the ports conducts virtually all of the oil onto the ball for distribution over the inverted conical spiral heating element. When the oil is hot, only the oil discharged by the intermediate port impinges on the ball for distribution over the heating element, the oil discharged by the side ports impinging on the side wall of the housing fo…
