An oil filler neck assembly is provided for an internal-combustion engine, which includes a hinged lid and a lock. The lock, in turn, includes a rotating device and a fixing device. The rotating device is rotatably arranged in the lid. The fixing device is arranged in an oil feed opening. The lock can also be used at poorly accessible locations and causes a high sealing force.

The invention relates to a cover plate ( ) for a crankcase ( ) of an internal combustion engine. Said cover plate ( ) extends over the entire surface area of the crankcase ( ). The auxiliary aggregates ( ) and filters are mounted on the cover plate ( ). In addition, the cover plate ( ) comprises channels for guiding media. The invention is advantageous in that it facilitates mounting.

The invention relates to a fuel injection system for an internal combustion engine, specially a diesel engine, comprising a crankcase and cylinder heads. Said system is provided with injectors to inject fuel into the combustion chambers of the internal combustion engine and a high pressure pump which supplies fuel to a common rail supplying fuel to the injectors via high pressure lines. According to the invention, the common rail is lodged in or on the walls of the crankcase. This arrangement of the common rail track and preferably also that of the fuel injectors and the high pressure lines in the housing of the internal combustion engine optimally protects the fuel injection system from external influence and damages while at the same time hermetically closing it from the outside by forming an internal leakage chamber.

Two components, such as an engine block (1) and a gear case (2), are coupled to each other by at least two flexible coupling links (7, 8) and by a rigid coupling link (10). One end of each flexible coupling link is connected to the engine block or gear case by a first screw connector (11, 11A, 11B) having a threaded bolt (13) passing through a twin cone (16) acting as a centering member. The conical surfaces of the twin cone centering member (16) cooperate with respective conical surfaces (12) in the gear case (2) and in an expander ring (17) bearing with its outer surface against an inner surface of a hole in the coupling link (7, 8) or an intermediate bushing in the coupling link, whereby the force transmitting connection is accomplished with radial clamping forces. The cooperation of the conical surfaces compensates for alignment tolerances and uneven stress distributions are avoided.

A fluid flow machine of the radial type of construction with adjustable guide blades in a radially extending annular channel of the fluid flow housing. The bearing support of the guide blades takes place in a guide blade carrier that represents a one-piece bearing cage with lateral flow surfaces for the guide blades. The guide blade carrier is composed of two bearing rings which are combined into one structural unit by way of fixed connecting webs disposed in the flow path. In this structural unit, the space for the guide blades can be machined very accurately in its axial width to maintain the tolerances which means small gap losses and correspondingly favorable efficiencies. Since the guide blade carrier is so arranged in the housing that expansions of the housing by reason of heat or pressure warping are not transmitted, the gap tolerances can be selected correspondingly still smaller, and the efficiency can be still further improved. It is also significant that the fluid flow machine and its components can be constructed particularly simple from a constructive point of view and particularly reliable in operation by means of the housing-independent bearing support of the guide blades in the guide blade carrier.
