Problems solved by technology

[0013] This known device presents the disadvantage that when the filter element has to be replaced, the drain line also has to be disassembled from the cover of the oil separator
[0014] This means that the drain line may be damaged and / or the drain line is connected incorrectly when refitting the filter element and cover of the oil separator

Embodiment Construction

[0034] figure 1 The compressor device 1 shown comprises an oil-filled compressor element 2, which in this example is of the known screw type and has a housing 3 in which two meshing screw rotors 4 is driven by motor 5.

[0035] It is clear that the compressor element 2 may also be another type of compressor element, such as a turbo compressor element, without departing from the scope of the present invention.

[0036] The housing 3 is provided with an inlet 6 for the supply of a gas to be compressed, for example air or another gas or a mixture of gases.

[0037] The housing 3 is provided with an outlet 7 connected to an outlet duct 8 . An outlet conduit 8 is connected to an inlet 9 of an oil separator 10 . This inlet 9 is placed tangentially.

[0038] The outlet 11 of the purified gas of the oil separator 10 can be connected directly or via a cooler 12 to a downstream consumer network 13 which will lead to the consumer network 13 where the gas is directed to drive various ...

Abstract

Oil separator that is provided with a housing (15) with an inlet (9) for an oil-gas mixture and which defines a space (16) that is closed off by means of a lid (17), whereby a screen (23) is provided in the aforementioned space (16) in which a filter element (25) is affixed and a pipe or collector (26) that connects the interior (27) of the filter element (25) to an outlet (11) in the housing (15} for purified gas, whereby the oil separator (10) is provided with a drainage line (35) for the removal of the oil that has been filtered out, characterised in that the drainage line (35) ensures the removal of the oil that has been filtered out from the underside of the filter element (25) directly to an outlet (37) for oil in the housing (15).

Description

technical field [0001] The invention relates to an oil separator. [0002] More specifically, the present invention relates to an oil separator provided with a housing having an inlet for an oil-air mixture and delimiting a space closed by a cover, wherein said space a screen is provided, and a duct or collector in which the filter element is fixed and which connects the interior of the filter element to an outlet for purified gas in the housing, Therein, the oil separator is provided with a drain line for draining filtered oil. Background technique [0003] Such oil separators are already used in oil injected compressors, where the oil-gas mixture from the outlet of the compressor element is directed to the oil separator before being directed to a consumer, eg compressed gas. [0004] In an oil separator, the oil-gas mixture to be treated is brought into the space between the screen and the housing via an inlet in the housing through which the oil-gas mixture will flow, s...
