Abstract
An oil separator connected to a machine operating with pulsating compressed air for separating an oil mist which is otherwise expelled together with the air and is let out in the ambient atmosphere when the compressed air is drained from the machine, the oil separator consists essentially of a tube or hose open at each end and connected at one end to the air outlet of the machine operating with compressed air, a tubular scraper sleeve (3) coaxially mounted in said tube through the other end and spaced radially therefrom, said tubular scraper sleeve extending substantially inside said tube or hose and some distance outside said tube or hose thereby forming an annular space between the overlapping portions of said sleeve and said tube or hose thereby providing free flow areas in said tube or hose, said sleeve and the annular space between the tube or hose and the sleeve, said annular space being provided with a plurality of channels surrounding said scraper sleeve and opened at each end so as to permit free flow therethrough, said channels extending substantially co-axially with the flow direction of the air between the overlapping portions of scraper sleeve and the tube or hose in w…
