ABSTRACT:
A liquid-injected compressor with at least two cooperating compressor elements (2 and 3) is provided. The compressor elements are mounted in a housing (1). At least one of the compressor elements is rotatable and is bearing-mounted with a shaft end (7, 8, 13, 14) in the housing (1). The compressor is provided with an inlet (22) and an outlet (17-18-19) which are connected to the inside of the housing (1). The shaft end (14) of the rotatable compressor element (3) is situated in the outlet (17-18-19) in the housing (1). At least one body (20 or 41), made of material which is permeable to gas, is fixed on this shaft (14), forming a filter which practically entirely seals the outlet (17-18-19) and only lets the compressed gas through.
