    A reciprocating internal combustion engine comprises an engine block, which includes cylinders, cylinder heads, pistons, connecting rods, a crankshaft and the mainshaft bearings for the crankshaft. That engine block is held in an outer pan by means of annular supporting elements, which are provided at both ends of the engine block and are coaxial to the crankshaft and insulate against a transmission of structure-borne noise. The engine block is sealed to the upper edge portion of the outer pan only by an oil seal. The outer pan consists of two parts, which are connected by screws. To prolong the service life of the annular supporting elements and to reduce the manufacturing costs, the outer pan has a parting plane which contains the axis of the crankshaft. The supporting elements are secured in the outer pan merely by being clamped between the two parts of the pan.

    The invention relates to mechanical engineering, in particular, engine-building, namely, to oil-sealing devices, isolating the case noise of an internal combustion engine.
    The aim of the invention is to increase the durability of an oil seal device that insulates the case noise of an internal combustion engine.
    Fig. 1 shows a fragment of an internal combustion engine; figure 2 - the internal combustion engine, end view; on fig.Z - variant of the internal combustion engine according to figure 1, section.
    The internal combustion piston engine contains a power unit consisting of cylinders, 1Ц1 LINDROE heads, pistons, connecting rods, a crankshaft 1 with corona bearings, and is installed in the external bath 2 with help of oil-tight, annular, insulating support elements 3, made of elastic material, located coaxially to the crankshaft 1 on the front sides of the power unit in the external bath 2, made of two parts 4 and 5 connected by screws 4, sealing along the upper edge of the bath 2 and the power block ka (not shown) holds only oil-tightness, with the connector 4 connected with screws plane 7

    Parts 5 and 6 of the external bath 2 are made along the axis of the crankshaft 1, and supporting elements 3 are fixed between parts 5 and 6 of the external bath
    5 2 using the outer rings 8 associated with them. From the side of the crankshaft 1, the supporting elements 3 rest on the inner rings 9, the outer 8 and inner 9
    10 rings are connected to the support element 3 by vulcanization. The inner rings 9 are connected to the power unit or to the main bearings 10 of the crankshaft 1.
    15 According to FIG. 3, the supporting elements 3 are supported on the inner rings 9 and clamped in cylindrical grooves (not shown in both parts 5 and 6 of the outer bath. 2.
    20 Execution of the plane 7 of the connector passing through the axis of the crankshaft 1 allows the supporting elements 3 to be held with the outer rings 8 only by clamping with screws 4
    25 parts 5 and 6 of the external bath 2, i.e. allows to exclude the use of special screws for engine flanges. Since the support elements 3 are not fixed through the flanges,
    3Q possible. when processing, large tolerances with respect to the axis of the crankshaft, which are compensated by the device, excluding the stresses inside the bearing elements, which increases their service life. It is possible to use the device without an outer ring 8.
