A pressure control valve serves to regulate the fuel pressure in a fuel system. The pressure control valve includes a valve housing, at least one inlet, at least one outlet, and at least one prestressed, electrically actuatable, and at least regionally ball-shaped valve member. The valve member cooperates with a valve seat structurally connected to the housing. To make it possible to achieve stable closed- and/or open-loop control properties of the pressure control valve, it is proposed that the valve seat widen conically toward the valve member, and the ball diameter of the valve member is selected such that with the valve closed, the valve member touches the valve seat in the vicinity of its farther end.

The invention joins the intake module or intake tube to the engine with the aid of a displaceable retaining element. The retaining element, which in the mounted state is under initial tension, is braced against an engine retention face associated with the engine and against at least one counterpart intake module retention face joined to the intake module or intake tube. Because of the displaceability of the retaining element, the expense and effort of mounting and dismantling the intake module or intake tube to the engine by screws are substantially reduced. The engine is intended in particular for motor vehicles.
