Claims
- 1. An oil separator for separating oil from oil-charged air, said oil separator comprising a mounting member, a housing secured to said mounting member to form an enclosed chamber inside said housing, an inlet for admitting oil-charged air into said chamber, an air outlet for discharging filtered air from said chamber, an oil outlet for discharging separated oil from said chamber, a filter unit in said chamber interposed between said inlet and said air outlet, said filter unit comprising a support body, a coalescer element supported on a surface of said support body, and first and second end gaskets in which respective axial ends of said support body and said coalescer element are received, said end gaskets fastening said coalescer element to said support body and sealing said filter unit in said chamber, each of said first and second end gaskets comprising a molded component configured as a lipped gasket, and said coalescer element being releasable from said support body by separating said end gaskets, whereby said coalescer element can be disposed of separately from said support body.
- 2. An oil separator according to claim 1, wherein each of said first and second end gaskets comprises a molded component in which respective axial ends of said support body and said coalescer element are embedded to bond the coalescer element to the support body.
- 3. An oil separator according to claim 2, wherein each of said first and second end gaskets is a two component element comprising a first component which penetrates into the coalescer element to seal and bond the coalescer element to the support body and a second component which forms an elastomeric seal.
- 4. An oil separator according to claim 1, wherein said filter unit is mounted inside said chamber so as to be spaced from said housing, said filter unit being held between said mounting member and an end plate with one of said end gaskets sealingly contacting the mounting member and the other of said end gaskets sealingly contacting the end plate, and said end plate being secured by a central threaded bolt extending therethrough, whereby the housing can be detached from the mounting member without releasing the filter unit.
- 5. An oil separator according to claim 1, wherein said coalescer element comprises a nonwoven web material.
- 6. An oil separator according to claim 1, wherein said coalescer element comprises a foam material.
- 7. An oil separator according to claim 1, further comprising a separating unit in said chamber interposed between said filter unit and said air outlet.
- 8. An oil separator according to claim 7, wherein said separating unit comprises a separating element supported on a support tube.
- 9. An oil separator according to claim 8, wherein said separating unit engages said mounting member independently of said filter unit, and said filter unit can be exchanged separately from said separating unit.
- 10. An oil separator according to claim 7, wherein said separating element comprises a nonwoven web material.
- 11. An oil separator according to claim 7, wherein said separating element comprises a foam material.
