Abstract

Die Erfindung betrifft eine Brennkraftmaschine mit zwei in deren Zylinderkopf' (1) nebeneinander angeordneten Nockenwellen (4, 5), an denen jeweils eine Vorrichtung (8, 9) zum Variieren der Steuerzeiten der Gaswechselventile der Brennkraftmaschine befestigt ist. Die Zu- und Abführung des hydraulischen Druckmittels zu und von den Vorrichtungen (8, 9) erfolgt durch jeweils ein elektromagnetisches Steuerventil (15, 16) welches jeweils aus einem in eine Ventilaufnahme (19, 20) einsteckbaren Cartridge und aus einem mit diesem verbundenen Elektromagneten (23, 24) mit einem an dessen freier Stirnseite (25, 26) angeordneten elektrischen Steckkontakt (27, 28) besteht.The invention relates to an internal combustion engine with two in the cylinder head ' (1) side-by-side camshafts (4, 5), each with one Device (8, 9) for varying the timing of the gas exchange valves Internal combustion engine is attached. The supply and discharge of the hydraulic Pressure medium to and from the devices (8, 9) takes place in each case electromagnetic control valve (15, 16) which each from a Valve holder (19, 20) insertable cartridge and from one with this connected electromagnets (23, 24) with one on its free end face (25, 26) arranged electrical plug contact (27, 28).

Erfindungsgemäß sind die Ventilaufnahmen (19, 20) als gesonderte Flanschhalterungen ausgebildet, welche direkt oberhalb der Radiallager der Nockenwellen (4, 5) derart auf dem Zylinderkopf der Brennkraftmaschine angeordnet sind, dass die Steuerventile (15, 16) mit ihrem Cartridge voneinander wegweisend und mit ihren Elektromagneten (23, 24) sich gegenüberliegend auf einer gemeinsamen, quer zur Längsachse der Nockenwellen (4, 5) verlaufenden Längsachse nebeneinander angeordnet sind.

Figure 00000001
According to the invention, the valve receptacles (19, 20) are designed as separate flange brackets, which are arranged directly above the radial bearings of the camshafts (4, 5) on the cylinder head of the internal combustion engine in such a way that the control valves (15, 16) point the way away from one another with their cartridge their electromagnets (23, 24) are arranged opposite each other on a common longitudinal axis running transversely to the longitudinal axis of the camshafts (4, 5).
