Claims
- 1. An oil filter unit for attachment to an aperture in a conduit of an accumulator in an air-conditioning system, said oil filter unit comprising:
- a thermoplastic frame having at least one peripherally disposed aperture and an open end;
- a filter material covering said at least one peripherally disposed aperture for filtering particles from the oil;
- a disk mounted within said thermoplastic frame, said disk having transverse extending portions having an opening therethrough; and
- a tube located in said opening of said transverse extending portions of said disk and extending into said defined thermoplastic frame at one end thereof and through said opening into said conduit at an opposite end thereof,
- whereby said tube when located in said opening of said transverse extending portions of said disk prevents collapsing of said transverse extending portions so as to ensure continuous communication of oil between said filter unit and said conduit of said accumulator.
- 2. An oil filter unit according to claim 1 wherein said tube consists of a metal material.
- 3. An oil filter unit according to claim 1 wherein said tube consists of an alloy.
- 4. An oil filter unit according to claim 1 wherein said tube consists of a thermoplastic material having a hardness higher than said material of said disk.
- 5. An oil filter unit according to claim 1 further comprising a conduit clamp for engaging an outer diameter of said apertured conduit for securing said oil filter unit to said conduit.
- 6. An oil filter unit as claimed in claim 5 wherein said oil filter unit is integrally joined to said conduit clamp.
- 7. An improved air-conditioning system of the type having an accumulator with a conduit having an aperture therein, an oil filter apparatus attached to said conduit surrounding said aperture, said oil filter apparatus including a filter unit, a conduit clamp joined with said filter unit and a disk member having transversely extended portions having an opening therethrough, one of said extended portions extending in a direction away from said disk member and into said aperture of said conduit, wherein the improvement comprises:
- a rigid hollow tubular support member located in said opening of said extended portions of said disk member, and passing into said aperture of said conduit so as to provide support for said extended portions of said disk member thereby preventing collapsing of said extended portions, said rigid hollow tubular support member further having an internal passage for ensuring continuous communication of oil between said filter unit and said conduit.
