In a fluid coupling with a baffle plate protruding on the side of an inner peripheral surface of a circulating circuit, a clutch chamber is defined between a back of a turbine impeller and a side cover covering the back of the impeller, to communicate with an outer periphery of the circulating circuit. The clutch chamber is divided by a clutch piston into an inner chamber portion on the side of the turbine impeller and an outer chamber portion on the side of the side cover. The clutch piston is axially movably connected to the turbine impeller, thereby constituting a lock-up clutch, so that a first oil passage leading to the outer chamber portion and a second oil passage leading to an inner periphery of the circulating circuit are put into alternate communication with a discharge portion of an oil pump and with an oil reservoir in a switched manner.

The printing unit according to claim 3, wherein said bearing device is formed by a perforated plate at least approximately following the curvature of said sheet bearing surface of said impression cylinder. 13. The printing unit according to claim 3, wherein said bearing device includes parallel sheet guide rails at least approximately following the curvature of said sheet bearing surface of said impression cylinder. 14. The printing unit according to claim 3, wherein said bearing device includes a lateral part for covering an interspace between said muffling element and said impression cylinder at least at one side of the conveying path. 15. The printing unit according to claim 3, wherein said bearing device includes a lateral part for shielding said impression cylinder at least at one end face thereof. 16. The printing unit according to claim 3, wherein said bearing device includes a lateral covering part for shielding said nip at least at one side of the conveying path. 17. The printing unit according to claim 16, including a further muffling element disposed at said lateral covering part. 18. A sheet fed rotary offset printing machine having at least one printing unit through which sheets pass in a processing direction along a conveying path, the printing unit comprising: an impression cylinder having a sheet bearing surface; a blanket cylinder, said blanket cylinder and said impression cylinder forming an impression nip, a first wedge-shaped space, with respect to the processing direction, upstream from said impression nip, and a second wedge-shaped space downstream from said impression nip; and at least one muffling element disposed within said second wedge-shaped space. 19. The printing unit according to claim 3, including a footstep for accessing the printing unit, said bearing device being attached to said footstep. 19910200, Miller et al., 180/197; US-5083986, 19920100, Teraoka et al., 475/086; US-5119298, 19920600, Naito, 180/248; US-5199325, 19930400, Reuter et al., 180/233; US-5215160, 19930600, Williams et al., 180/197; US-5251719, 19931000, Eto et al., 180/197
