1. Flytande kolvtapp (2) tili förbränningsmotor med oljekyld kolv (1) av den typ som uppvisar en genomgäende passage som le-der kyloljan frän en i vevstaken upptagen kanal via dennas kolv-tappslager (4, 5) tili koiven via minst en av kolvens kolv-tappslager, kännetecknad därav, att tappen (2) är till-verkad i ett stycke och att nämnda passage utgörs av i förbindelse med varandra stäende frän tappens periferi i höjd med dennas lagring i vevstakens kolvtappslager (9) tili tappens periferi i höjd med ätminstone dess ena lagring (4, 5) i koiven genom tappens i övrigt massiva centrala kärna diagonalt dragna kana- ler (19-24).
2. Flytande kolvtapp enligt patentkravet 1, kännetecknad därav, att de kanaler (19-24), som löper diagonalt frän tappens periferi i höjd med dennas lagring i vevstakens kolvtappslager (9) tili tappens periferi vid en och samma av dess lagringar i koiven skär varandra kring tappens centrallinje där de i tappen uppkomna belastningsväxlingarna är minsta.
3. Flytande kolvtapp enligt patentkravet 1 eller 2, kännetecknad därav, att de kyloljekanaler (19-24) som löper diagonalt genom tappen parvis utgär frän gemensamma öppningar (16, 17, 18) i tappens periferi i höjd med dennas lagring i vevstakens kolvtappslager och därifrän utgär raot tappens periferi vid vardera av dess respektive ändar i höjd med tappens lagringar (4, 5) i koiven.
4. Flytande kolvtapp enligt patentkravet 3, kännetecknad därav, att vardera paret av de parvis frän gemensamma öppningar utgäende kanalerna (19, 20, 21, 22, 23, 24) löper diagonalt genom ett och samma tappens centralaxel lagda del-ningsplan.
