Device for separating liquid from a gas stream coming from a liquid injected vacuum pump or compressor

A method for separating liquid from a gas stream within a liquid injected vacuum pump or compressor, said method comprising the steps of:

• providing two communicating vessels having a bottom plate and lateral walls extending from said bottom plate and having a first height, said two vessels having a common section along a back side of the two communicating vessels extending over at least a part of said height, wherein the common section is created by cutting said lateral wall along the height so as to create two wall parts and adjoining said wall parts over at least a part of said height and positioning said common section on the opposite side of an inlet opening along a front side of the two communicating vessels;
• providing at least one bucked shaped vessel within each of the two communicating vessels;
• providing a fluid passage between the wall of each of the two communicating vessels and the wall of each of the two bucket shaped vessels for allowing a fluid to pass there through;
• directing a fluid flow through said inlet opening and splitting the fluid flow from said inlet opening into two flows directed through the fluid passage wherein a distance is created between said inlet opening and the common section in a way such that the gas stream travels said distance before the gas stream is split into two separate flows by the common section into said two communicating vessels;
• collecting the liquid dripping from said fluid flowing through the two communicating vessels on the bottom plate;
• and
• providing a lid comprising an outlet opening and directing the fluid passing through said fluid passage through the outlet opening.
