A compressor drive (10) controls the driving connection between a vehicle engine (12) and an air compressor (14). The drive (10) includes a clutch disc pack (82) which is lubricated by lubricating fluid communicated through a passage (40) on the spindle (36) upon which the disc pack (82) is mounted. A sleeve (96) mounted in the passage (40) provides a flow-restricting orifice (102) which controls communication into an annular chamber (100) defined between the sleeve (96) and the passage (40). Axial-spaced apertures (104) permit fluid communication from the annular chamber (100) to each pair of plates (84, 86) in the disc pack (82).
