Abstract

The invention relates to a fuel distribution block for an internal combustion engine that has a belt arrangement, said belt arrangement comprising a belt that is functionally connected to a belt pulley which is coupled to a shaft, in order to drive a unit, especially an engine unit, via a further belt pulley which is functionally connected to the belt. A belt deflecting device is arranged on the fuel distribution block to deflect the belt in order to minimize the physical size of the belt arrangement.

Abstract

The invention especially relates to a fuel pump for the compression of fuel, comprising at least two compressor pistons, an eccentric chamber which accommodates the at least two compressor pistons such that they can be displaced axially and which further accommodates an eccentric for driving the at least two compressor pistons, said eccentric being accommodated in the eccentric chamber such that it can rotate. The eccentric and the at least two compressor pistons are functionally interconnected such that the two compressor pistons are displaced axially for the compression of fuel. The eccentric chamber is at least partially filled with a lubricant.

Abstract

The invention relates to a rotary disk valve arrangement comprising a crankcase which accommodates a crank shaft, said crankcase having an inlet opening for fresh air, and at least two rotary disk valves for regulating the fresh air inlet into the crankcase, each of the at least two rotary disk valves having a rotational axis and being accommodated such that they can be rotated relative each other to release the inlet opening at least partially or close it, the at least two rotary disk valves being arranged on the crankcase on a coupling surface of said crankcase. The coupling surface has at least one further inlet opening and each of the at least two rotary disk valves has at least two rotary valve openings to release the at least two inlet openings at least partially.
