Abstract

A reciprocating-piston internal combustion engine has a drive-unit block 1 which consists of cylinders, cylinder heads, pistons, connecting rods, a crankshaft and its bearings. This drive-unit block 1 is mounted, insulated against solid-borne sound, in an external trough 2. Between the drive-unit block 1 and the upper edge of the external trough 2 is seated an elastically flexible force- free oil seal 5 surrounding the drive-unit block 1 in a frame-like manner. The oil seal 5 engages, in the region of the upper edge of the external trough 2, with pressed- in webs 7, into grooves 3, 4, 5, 6 which are arranged, on the one hand, in the drive-unit block 1 and, on the other hand, in the wall 2a of the external trough. In order to ensure that the oil seal performs its function for long periods of time in spite of pronounced relative movement of the drive-unit block 1 and of the external trough 2, the webs 6, 7 of the frame-like oil seal 5 are connected by means of a thin-walled bulged-out concertina 8. This concertina 8 has in each case, at the transitions of adjacent frame legs, a wave-like depression 11 running from one frame leg to the other. <IMAGE>
