Characteristic-map-regulated oil pump
A familiar pendulum slide cell pump is used as the oil pump. The pump shaft for the supply is seated off-center in the housing and the vanes are displaced radially during rotation. This means that the vane chambers form different volumes. When the volume rises, the oil is taken in; when the volume decreases, oil is pressed into the oil ducts.
