Abstract
The invention discloses an internal combustion engine in which the open housing oil pressure pump (1) is closed by securing it directly onto the cylinder head (5), the moving elements of the pump being fixed to the camshaft (20) by means of an axial abutment (29). Sealing is assured on the one hand by means of an O ring (25) between the pump (1) and the head (5), on the other hand by means of a lip seal (45) and a breather (51). The axial play (44), also affecting the sealing, is maintained at the desired amount by means of the levelled washer (47). The application is to all engines for which reduction in weight, volume and maintenance cost is sought.
